IN THE MATTER OF RAMBUS INCORPORATED
Docket 9302; File No. 0110017
Initial Decision, February 24, 2004
INITIAL DECISION
Before: Stephen J. McGuire, Chief Administrative
Law Judge

One is the introduction, which includes a summary of
the allegations contained in the Complaint; the
defenses asserted in Respondent’s Answer; the issues
presented; the procedural background; a comment on
the evidence; and a summary of the decision. Part
Two contains the separately numbered findings of
fact. Part Three contains the analysis and conclu
sions of law, which provides an overview of the legal
theories asserted by Complaint Counsel; sets forth
the applicable law on each of the elements necessary
to find a violation; and then applies the law to the
facts established at trial. Part Four contains the
summary of the conclusions of law and the Order of
the Court.
I FEDERAL TRADE COMMISSION
COMPLAINT
The Federal Trade Commission (“FTC”) issued its
Complaint in this matter on June 18, 2002. The
Complaint charges that Respondent, Rambus Inc., a
corporation, violated Section 5 of the Federal Trade
Commission Act (“FTC Act”), as amended. 15 U.S.C.
§ 45.
417a
The Complaint charges Respondent with three vio-
lations. The first violation charges that Respondent
engaged in a pattern of anticompetitive and ex-
clusionary acts and practices, whereby it obtained
monopoly power in the synchronous DRAM technol-
ogy market and narrower markets encompassed
therein, in violation of Section 5 of the FTC Act.
(Complaint J 122). The second violation charges that
Respondent engaged in a pattern of anticompetitive
and exclusionary acts and practices with a specific
intent to monopolize the synchronous DRAM techno!-
ogy market and narrower markets encompassed
therein, resulting, at a minimum, in a dangerous
probability of monopolization in each of the markets,
in violation of Section 5 of the FTC Act. (Complaint
{ 123). The third violation charges that Respondent
engaged in a pattern of anticompetitive and exclu-
sionary acts and practices, whereby it unreasonably
restrained trade in the synchronous DRAM technol-
ogy market and narrower markets encompassed
therein, which acts and practices constitute unfair
methods of competition in violation of Section 5 of the
FTC Act. (Complaint J 124).
The Complaint alleges that Respondent partici-
pated in the work of the JEDEC Solid State Tech-
nology Association (“JEDEC”), an industry standard
setting organization in which Respondent was a reg-
ular participant, without making it known to JEDEC
or to its members that Respondent sought to ob-
tain patents on technologies adopted in the relevant
JEDEC standards. (Complaint {7 2, 43, 44, 45, 46).
Respondent’s alleged scheme further entailed perfect-
ing its patent mghts over these same technologies
and then, once the standards had become widely
adopted within the DRAM industry, enforcing such
patents worldwide against companies manufacturing
418a
memory products in compliance with the JEDEC
standards. (Complaint {J 2, 43, 44, 45, 46).
Respondent is alleged to have concealed informa-
tion in violation of JEDEC’s operating rules and
procedures which Complaint Counsel argue imposed
upon JEDEC members an obligation to “disclose any
patents, or pending patent applications, involving
the standard-setting work.” (Complaint {J 20, 21, 24,
79). In addition, the Complaint alleges a “basic rule”
of JEDEC to avoid anticompetitive activity and a
commitment to avoid, where possible, incorporation
of patented technologies. (Complaint {If 17, 18, 19,
20, 22). The Complaint alleges that Respondent
violated these duties by conveying to JEDEC the
materially false and misleading impression that it
possessed no relevant intellectual property mghts.
(Complaint {{ 2, 80).
The Complaint further alleges that Respondent’s
conduct caused anticompetitive effects including in-
creased royalties, increase in the price of synchronous
DRAM and products incorporating synchronous
DRAM, decreased incentives to produce memory
using synchronous DRAM technology, and harms to
standard setting organizations and activities. (Com-
plaint 79 119, 120).
il. RESPONDENT’S ANSWER
In its Answer filed on July 29, 2002, Respondent
alleged as an affirmative defense that the Complaint
failed to state a claim under Section 5 of the FTC Act.
The Answer denied the material allegations of the
Complaint and asserted that the evidence would
show that JEDEC’s rules and policies did not impose,
and were not commonly understood to impose, the
419a
disclosure obligations set out in the Complaint.
(Answer, pp. 1-2).
Respondent asserted in its Answer that the
evidence would show that it did not have, until after
it left JEDEC, any undisclosed patents or patent
applications that contained claims reading on de-
vices manufactured in accordance with any JEDEC
standard. (Answer, p. 2). Respondent also asserted in
its Answer that the evidence would show that
JEDEC did not rely on any purported silence on
Respondent’s part at JEDEC meetings and instead
chose to adopt certain technologies because of the
cost/performance advantages of those technologies
and the absence of reasonable alternatives. (Answer,
p. 2).
Respondent’s Answer asserted that in light of the
absence of a duty to disclose, in light of the absence of
pending claims reading on JEDEC standards, and in
light of the other evidence to be considered at trial, it
would be clear that Respondent’s alleged failure to
disclose its potential intellectual property claims had
no anticompetitive effect in any market and that
Respondent had not violated Section 5. (Answer, pp.
1-3).
Ill. ISSUES PRESENTED
The issues presented in this case are:
(1) whether Respondent engaged in a pattern
of deceptive, exclusionary conduct by subverting
an open standards process;
(2) whether Respondent utilized such conduct
to capture a monopoly in technology-related
markets;
420a
(3) whether Respondent’s challenged conduct
violated principles of antitrust law; and
(4) whether Respondent’s conduct resulted in
anticompetitive injury.
IV. PROCEDURAL BACKGROUND
On June 18, 2002, the Commission issued its
Complaint. This case was initially assigned to Ad-
ministrative Law Judge (“ALJ”) James P. Timony.
Rambus filed a motion to stay the proceeding until
the Federal Circuit issued its decision in Rambus Inc.
v. Infineon Technologies, an appeal of a jury verdict
against Rambus. The Federal Circuit reversed the
jury verdict of fraud and remanded the case, as
discussed more fully in Part III, Section I.C. An
Order Denying Motion for Stay was issued in this
case on July 18, 2002. On July 29, 2002, Rambus filed
its Answer in this matter.
On February 26, 2003, ALJ Timony issued an
Order On Complaint Counsel’s Motions For Default
Judgment and For Oral Argument which imposed
seven rebuttable presumptions against Rambus
based on a finding of intentional destruction of evi-
dence. This Order is discussed in Part III, Section
I.B.
On February 28, 2003, ALJ Timony retired from
federal service. Stephen J. McGuire was _ subse-
quently appointed FTC Chief Administrative Law
Judge and assigned the Rambus matter.
Trial in this proceeding commenced on April 30,
2003. The 54 day administrative hearing produced a
voluminous evidentiary record including 44 live wit-
nesses, 1,770 admitted exhibits, nearly 12,000 pages
of trial transcript, and hundreds of pages of depo-
42la
sition transcripts. The last day on which testimony
was received was August 1, 2003. The parties then
filed Post-Trial Briefs, Proposed Findings of Fact,
and Conclusions of Law, and replies thereto. Closing
arguments and oral examination by the Court was
conducted on October 8, 2003. Following the closing
arguments, the hearing record was closed pursuant
to Commission Rule 3.44(c), by Order dated October
9, 2003. Due to the exceptional circumstances of the
complexity of the issues presented, the volumes of
evidence introduced at trial, and review of the com-
prehensive proposed findings of fact and post-hearing
briefs, it was necessary to extend the deadline for
filing the Initial Decision within one year of the
issuance of the Complaint. By Order dated December
23, 2003, the Commission also extended the time for
filing the Initial Decision within 90 days of the close
of the hearing record until February 17, 2004.
V. EVIDENCE
The Initial Decision is based on the transcript of
the testimony, the exhibits properly admitted in
evidence, and the proposed findings of fact, briefs,
conclusions of law, and replies thereto filed by the
parties. Once a finding of fact is established, it is
cited to in subsequent sections or in the analysis by
the designation “F.”’
' This opinion uses the following abbreviations for citations:
Comp. - Complaint
F. - Finding of fact
CX - Complaint Counsel Exhibit
RX - Respondent Exhibit
JX - Joint Exhibit
422a
The parties submitted extensive post-trial briefs
and reply briefs. The Initial Decision addresses only
material issues of fact and law. Proposed findings of
fact not included in the Initial Decision were rejected,
either because they were not supported by the
evidence or because they were not dispositive to the
determination of the allegations contained in the
Complaint. The Commission has held that Admin-
istrative Law Judges are not required to discuss the
testimony of each witness or all exhibits that are
presented during the administrative adjudication. Jn
re Amrep Corp., 102 F.T.C. 1362, 1670 (1983). Fur-
ther, administrative adjudicators are “not required to
make subordinate findings on every collateral con-
tention advanced, but only upon those issues of fact,
law, or discretion which are ‘material.” Minneapolis
& St. Louis Ry. Co. v. United States, 361 U.S. 173,
193-94 (1959).
Many of the documents and parts of the oral
testimony were received into the record in camera.
Where an entire document or where certain trial
testimony was given in camera treatment for trial,
but the portion of the document or the trial testimony
utilized in this Initial Decision does not rise to the
level necessary for in camera treatment, such infor-

Decision, pursuant to Commission Rule 3:45(a) (the
ALJ “may disclose such in camera material to the
extent necessary for the proper disposition of the
proceeding”). In accordance with 16 C.F.R. § 3.45(f),
material that has been given in camera treatment is

VI. SUMMARY OF THE DECISION
Complaint Counsel have failed to sustain their
burden of proof with respect al] three of the violations
alleged in the Complaint. First, the evidence at trial
establishes that Complaint Counsel failed to prove
the facts they alleged in the Complaint. Second, an
analysis of the legal theories advanced by Complaint
Counsel demonstrates that there is no legal basis for
finding a violation of Section 5 of the Federal Trade
Commission Act, either as based on other antitrust
laws or solely as an unfair method of competition.
Third, an application of the facts established at trial
to the legal theories asserted leads to the conclusion
that Complaint Counsel have failed to prove their
case.
The evidentiary record demonstrates that: (1) the
EIA/JEDEC patent policy encouraged the early, vol-
untary disclosure of essential patents and Respon-
dent did not violate this policy; (2) the case law upon
which Complaint Counsel rely to impose antitrust
liability is clearly distinguishable on the facts of this
case; (3) Respondent’s conduct did not amount to
deception and did not violate any “extrinsic duties,”
such as a duty of good faith to disclose relevant
patent information; (4) Respondent did not have any
424a
undisclosed patents or patent applications during the
time that it was a JEDEC member that it was
obligated to disclose; (5) amendments to broaden
Respondent’s patent applications while a member of
JEDEC were not improper, either as a matter of law
or fact; (6) by having a legitimate business justi-
fication for its actions, Respondent did not engage in
exclusionary conduct; (7) Respondent did not inten-
tionally mislead JEDEC by knowingly violating a
JEDEC disclosure rule; (8) there is no causal link
between JEDEC standardization and Respondent's
acquisition of monopoly power; (9) members of
JEDEC did not rely on any alleged omission or
misrepresentation by Respondent and, if they had,
such reliance would not have been reasonable; (10)
the challenged conduct did not result in anticom-
petitive effects, as Complaint Counsel did not
demonstrate that there were viable alternatives to
Respondent’s superior technologies; (11) the chal-
lenged conduct did not result in anticompetitive ef-
fects as the challenged conduct did not result in
higher prices to consumers; and (12) JEDEC is not
locked in to using Respondent’s technologies in its
current standardization efforts.
For these reasons, Complaint Counsel have failed
to sustain their burden to establish liability for
the violations alleged. Accordingly, the Complaint is
DISMISSED.
PART TWO: FINDINGS OF FACT
I. DRAM AND THE INVENTIONS OF DRS.
FARMWALD AND HOROWITZ
A. DRAM _ Applications in Computer
Systems
1. DRAM Defined
reenter
425a
1. DRAM stands for “dynamic random ac-
cess memory.” (Rhoden, Tr. 266). DRAM is a
type of electronic memory. (Rhoden, Tr. 266).
DRAM is “dynamic” because it needs to be
refreshed every fraction of a second. (Rhoden,
Tr. 266-67).
2. The primary use for DRAM is in com-
puter systems. (Rhoden, Tr. 267-68; Gross, Tr.
2272-73).
3. DRAMs are also used in a wide range of
other products involving computer systems.
(Sussman, Tr. 1362). These products include
printers, PDAs (personal digital assistants),
and cameras. (Kellogg, Tr. 4986-87; Tabrizi,
Tr. 9126-27; Krashinsky, Tr. 2770-71; Farm-
wald, Tr. 8206-07; Gross, Tr. 2272-73).
4. Typically, multiple DRAM chips are
placed on a memory module, which is a small
printed circuit board. (Rhoden, Tr. 272-73).
The module containing the DRAM chips
connects to a motherboard. (Rhoden, Tr. 270,
273). In some applications, such as graphics
cards, the DRAM chips are not put in memory
modules. (Wagner, Tr. 3871-72).
5. A DRAM is made up of a number of cells.
(Rhoden, Tr. 359). Information is stored in the
cell capacitor as either a high or low voltage.
(Rhoden, Tr. 359). The cells of the DRAM are
divided into an array via a series of rows and
columns with the cells located at the
intersections of those rows and columns.
(Rhoden, Tr. 359-60). Access to the cell
capacitor is made by activating a transistor,
which transfers the voltage in the capacitor to
426a
a column, also known as a bit line. (Rhoden,
Tr. 359-60).
6. In order for a DRAM to have any value, it
must be compatible and interoperable with the
other components in the same specific system
that include the DRAM. (Peisl, Tr. 4410; CX
1075 at 1; Heye, Tr. 3655-65; Jacob, Tr. 5562-
66).
2. The Production of DRAMs
a. The DRAM Manufacturing Process
7. The starting point in the manufacturing
process is a bare silicon wafer. (Becker, Tr.
1116-17).
8. During the course of the manufacturing
process, successive layers are built up on the
silicon wafer. (See generally Becker, Tr. 1116-
32). DRAMs require as many as twenty-two
distinct layers. (Becker, Tr. 1131). Each layer
requires a series of manufacturing steps.
(Becker, Tr. 1131-32). Processing the wafer
takes about four hundred manufacturing steps.
(Becker, Tr. 1118, 1131).
9. The manufacturing process is nonlinear,
meaning that a wafer will reenter different
processing areas of the fab a number of times.
(Becker, Tr. 1118). A processed wafer contains
hundreds of individual DRAM chips. (Becker,
Tr. 1117).
10. The processed wafer is electrically tested
in order to find the good chips. (Becker, Tr.
1132-34). Such testing, however, does not
identify all of the die with disqualifying
defects. More stringent testing is only possible
427a
after the die have been packaged. (Geilhufe,
Tr. 9570).
11. After testing, the wafer is cut into
individual DRAMs. (Becker, Tr. 1132-34). The
individual chips are then bonded to a metal
lattice like structure called a lead frame and
are covered with a black hard plastic mold
compound. (Becker, Tr. 1132-34).
12. After packaging, the good chips are built
into components and tested again. (Becker, Tr.
1135-36).
13. The tested components may also be as-
sembled onto circuit boards to create modules
and are further tested. (Becker, Tr. 1135; see
generally Becker, Tr. 1132-36 (describing the
process of how the chips are built into com-
ponents and connected to modules)).
14. The largest part of a DRAM, approxi-
mately ninety percent of the active area,
consists of the memory array, that is the
memory cells and related circuitry. (Geilhufe,
Tr. 9560). The remaining ten percent consists
of peripheral circuitry. (Geilhufe, Tr. 9560).
Circuitry for implementing the four features at
issue here — programmable column address
strobe (“CAS”) latency, programmable burst
length, dual edge clocking, and on-chip delay
lock loop (“DLL”) — are found in the peripheral
circuitry. (Geilhufe, Tr. 9559).
15. The vast majority of DRAM develop-
ment costs is spent on the memory array
portion of the DRAM, including the manufac-
turing process and equipment development.
(Geilhufe, Tr. 9560-61). Development costs for
428a
the peripheral circuitry are much lower. (Geil-
hufe, Tr. 9560-61).
b. The Various Phases of DRAM
Development
16. The development of the DRAM proceeds
along a number of “phases” and milestones.
Those are the design phase, the layout phase,
the simulation phase, the verification phase,
tape out, initial silicon, the validation phase,
internal qualification phase, and the produc-
tion phase. (Shirley, Tr. 4141-42; Reczek, Tr.
4306-41).
17. In the design phase, the DRAM design-
ers implement the DRAM specification as a set
of circuit designs or schematics. (Shirley, Tr.
4142-43).
18. In the layout phase, the layout designers
take the circuit designs created in the first step
and create a representation of the circuit de-
signs. (Shirley, Tr. 4143).
19. In the simulation phase, the design
engineers simulate the designs in order to
verify that the chips will perform as intended
before they are first manufactured. (Shirley,
Tr. 4144).
20. The verification phase involves ensuring
that the schematics created in the design
phase are in fact represented by the work done
in the layout phase. (Shirley, Tr. 4144-45;
Reczek, Tr. 4309).
21. Tape out involves the process of trans-
ferring the DRAM layout onto masks that will
be used in the fabrication of the DRAM.
429a
(Shirley, Tr. 4145). The collection of individual
masks necessary to fabricate a DRAM design
comprises a mask set. (Shirley, Tr. 4147).
22. A mask contains an image that is
transferred to the wafer through a process of
using light to expose the wafer to the image
pattern in the mask and using gasses to etch
the resulting pattern into the wafer. (Becker,
Tr. 1122-24).
23. At some DRAM manufacturers, includ-
ing Micron Technologies, Inc. (“Micron”), the
physical creation of masks is done by special-
ized firms that provide che service to the
DRAM manufacturers. (Shirley, Tr. 4145-46).
Other DRAM manufacturers, including Infin-
eon Technologies (“Infineon”), produce their
own masks. (Reczek, Tr. 4312).
24. The mask set, once it is received, is used
to create the first physical manifestation of the
DRAM chips on wafers. Those wafers repre-
sent a milestone and are referred to as “initial
silicon.” (Shirley, Tr. 4147).
25. Initial silicon is then tested in the
validation and internal qualification phases to
ensure that the DRAM on the wafers operate
the way they were intended (the validation
phase) and that the DRAM on the wafers
operate appropriately in the expected environ-
ments (the qualification phase). (Shirley, Tr.
4148-49).

c. Design Modification During
DRAM Production
26. The DRAM industry transitions between
different versions of DRAM quite frequently.
As a witness from Micron explained:
Switching from one product to another,
while still using the same core technology,
involves only changing priorities in design
and product engineering and may mean
some differences in our assembly and test
equipment purchases. SDRAM, SLDRAM,
nDRAM all use the same fab equipment
and core DRAM technology. In short, while
the flavors might change, it’s still a DRAM.
(RX 836 at 3) (emphasis added).
B. The Memory Bottleneck Problem
27. Dr. Michael Farmwald, one of the two
founders of Rambus, received his bachelor’s
degree in mathematics from Purdue University
in 1974. (Farmwald, Tr. 8058). He then earned
a Ph.D. in computer science from Stanford
University in 1981. (Farmwald, Tr. 8059).
While a graduate student at Stanford, Dr.
Farmwald was in charge of a supercomputer
project at Lawrence Livermore National Labs.
(Farmwald, Tr. 8059). After obtaining his
Ph.D, he continued to work at Livermore for
four years and then founded a company called
FTL (which stood for “Faster Than Light”),
whose goal was to build very fast computers.
(Farmwald, Tr. 8060-61). In 1988, Dr. Farm-
wald went to the University of Illinois to teach
in the computer science department. (Farm-
wald, Tr. 8063-64).
43la
28. While working as a professor at the
University of Illinois, Dr. Farmwald realized,
and it was a general perception in the DRAM
industry, that developments in microprocessor
technology would lead to significant speed in-
creases in microprocessors while memory chip
performance would not keep up. (Farmwald,
Tr. 8063, 8067). He recognized that the result
of these trends would be a “bottleneck” —
memory technology would limit computer
system performance. (Farmwald, Tr. 8068-69).
29. Moore’s law, named after Gordon Moore,
founder of Intel Corp. (“Intel”), predicts that
processor speeds will increase by a factor of
four every three years. (Farmwald, Tr. 8068).
This “law” has held true for over the last two
decades. (Farmwald, Tr. 8068). The perform-
ance of DRAMs, however, was increasing at a
lesser rate; while DRAMs were fast in com-
parison to microprocessors in the early 1980s,
as an historical matter, DRAM performance
had increased very slowly over time. (Farm-
wald, Tr. 8072).
30. Graphing predicted microprocessor
speeds against memory performance, Dr.
Farmwald predicted an ever increasing gap
between microprocessor performance and
DRAM performance. (Farmwald, Tr. 8071-73).
31. Assuming that the predicted DRAM
speeds were not improved, Dr. Farmwald
projected that the number of DRAMs needed
to support future microprocessors would be-
come extremely large over time. (Farmwald,
Tr. 8073).
432a
32. The increasing number of DRAMs
needed to support faster computers was also
consistent with Dr. Farmwald’s experience
that microprocessors were demanding higher
and higher bandwidth memory systems
(“bandwidth” being the amount of information
that can be transferred over a specific period of
time). (Farmwald, Tr. 8076-79).
33. Dr. Farmwald also plotted the projected
price for computers, which showed that the
cost for computer systems was dropping over
time. (Farmwald, Tr. 8074-75). Comparing
these projected costs with the number of
DRAMs that would be required to support the
bandwidth needs of faster microprocessors, Dr.
Farmwald knew that “there was something
broken” — the costs of the thousands of DRAMs
needed at higher microprocessor speeds would
prevent the decline of computer system prices.
(Farmwald, Tr. 8075-76).
34. Later, a 1992 Rambus “Corporate Back-
grounder” described the issue: “[o]ne of the
most serious problems is the chronic speed
mismatch between processors and main mem-
ory. Designers refer to this as the memory
bottleneck. The data transfer rates of memory
ICs [integrated circuits] lag far behind a proc-
essor’s ability to handle the data.” (RX 81 at 4).
35. To meet the higher bandwidth needs of
microprocessors without the overwhelming
cost of thousands of DRAMs, DRAM perform-
ance had to increase at a higher rate. (Farm-
wald, Tr. 8076).
433a
36. Years later, Dr. Farmwald’s 1988 ob-
servations were recognized by others in the
industry. For example, an April 1992 internal
memorandum of Siemens AG (“Seimens”)
states that “[ajs a result of the trend toward
increasingly faster RISC and CISC processors,
the DRAM interface has become more and
more of a problem for system ‘developers. In
order to eliminate this data transmission rate
bottleneck, various competing concepts regard-
ing the design of newer DRAMs have emerged
....” (RX 285A at 1).
37. Similarly, an Octobe- 1992 article pub-
lished in the Institute of Electrical and
Electronic Engineers, Inc. (“IEEE”) Spectrum
warned, “[i]f the price-to-performance ratio of
computer systems is to keep improving, the
gap in speed between processors and memory
must be closed.” (RX 329 at 1). IEEE Spectrum
is the overall general magazine for the IEEE, a
professional organization of electronic and
electrical engineers. (Prince, Tr. 8972-73). The
article went on to explain that “the accepted
dynamic RAM (DRAM) architectures and
solutions have been pushed to their limits. A
basic change in architecture seems the only
way to obtain an urgently needed increase in
memory speed.” (RX 329 at 1). This article
reflected a general discussion within the in-
dustry in 1992 that computer companies
needed faster DRAMs. (Prince, Tr. 8977-78).
38. Another article in the October 1992
IEEE Spectrum stated, “[i]f dynamic RAMs
and processors are to trade data at close to top
speed, the interface between them must be re-
434a
engineered. .. . None of the types of interfaces
now popular can do this while conserving
power and cost to the desired degree.” (RX 333
at 1).
39. In February 1994, Dr. Betty Prince, a
long-time consultant in the DRAM industry
and the author of five books on DRAM
technologies (Prince, Tr. 8970-72), wrote in an
article published in IEEE Spectrum that “[t]he
mismatched bandwidths of fast processors and
the slower memory chips they must employ are
a problem of long standing. Processors now as
always require more data per unit time than
many standard memory chips have been de-
signed to provide.” (RX 465 at 1). She also
provided a graph showing that this perform-
ance gap was increasing over time. (RX 465
at 1). Dr. Prince agreed that the performance
gap she wrote about created a bottleneck.
(Prince, Tr. 8990-91).
40. Intel saw the memory bottleneck coming
in 1995, and the recognition of this bottleneck
prompted Intel to investigate various memory
technologies in an effort to remedy the situa-
tion. (MacWilliams, Tr. 4929-30).
C. Farmwald’s and Horowitz’s Inventions
Solve the Memory Bottleneck Problem
by Addressing Numerous Issues
41. In 1988, Dr. Farmwald conceived the
general idea of a new memory interface and
protocol (an organization of the bits and timing
of bits transferred by a memory chip) that
would allow a single DRAM chip to have
higher performance than a board Dr. Farm-
435a
wald had designed containing 320 existing
DRAM chips. (Farmwald, Tr. 8086-88).
42. In order to progress beyond his initial
ideas Dr. Farmwald realized that he needed
the assistance of an ex ert in circuit design.
(Farmwald, Tr. 8089). Dr. Farmwald sought
the help of a former colleague — Dr. Mark
Horowitz, a professor at Stanford. (Farmwald,
Tr. 8089-90).
43. Dr. Horowitz had completed both his
bachelors and masters degrees in electrical
engineering from MIT in four years, receiving
the degrees in 1978. (Horowitz, Tr. 8477). After
working for a year at Signetics, he then earned
a Ph.D. in integrated circuit design from
Stanford University in 1983. (Horowitz, Tr.
8477-80). Dr. Horowitz has been a professor
in the electrical engineering and computer
science departments at Stanford University
since the mid-1980’s. (dorowitz, Tr. 8476). Dr.
Horowitz currently holds two endowed chairs
at Stanford. (Horowitz, Tr. 8482).
44. Dr. Farmwald convinced Dr. Horowitz to
take a year’s leave from Stanford to further
explore their ideas. (Farmwald, Tr. 8092-93).
Starting in the spring of 1989, the two worked
from Dr. Horowitz’s Palo Alto home. (Farm-
wald, Tr. 8093-94).
45. Dr. Horowitz’s goal was to build the
fastest possible DRAM interface. (Horowitz,
Tr. 8486). Drs. Horowitz and Farmwald deter-
mined that 500 megahertz (“MHz”) DRAM
operation might be possible, and they worked
toward that goal. (Horowitz, Tr. 8505-06).
436a
46. In creating their inventions, Drs. Farm-
wald and Horowitz had to solve numerous
problems. (Horowitz, Tr. 8487). They realized
that current memory interfaces could not run
at high speeds as a result of electrical issues,
clocking issues, and issues relating to the
protocol, and that they would need innovations
in each of these areas in order to meet their
goal. (Horowitz, Tr. 8487-88).
1. Electrical Issues
47. With respect to electrical issues, Drs.
Farmwald and Horowitz needed to develop
driver and receiver circuitry that could gen-
erate very high-speed signals, and they also
needed to develop a bus that would allow the
signals to propagate. (Farmwald, Tr. 8118-20;
Horowitz, Tr. 8488).
48. Drs. Farmwald and Horowitz developed
a number of solutions to the electrical issues
that arose. First, they realized that reflected
signals from the end of the bus lines would be
a serious problem at high speeds and conceived
the idea of introducing resistors to “terminate”
the bus lines and reduce reflections. (Horowitz,
Tr. 8492-93).
49. Second, Drs. Farmwald and Horowitz
realized that the high voltage signaling then in
use would generate too much power at high
speeds, and they developed low voltage signal-
ing using a particular kind of driver called
a “current mode” or “current source” driver.
(Farmwald, Tr. 8119, 8144-45; Horowitz, Tr.
8494-95; RX 82 at 9).
437a
50. Third, Drs. Farmwald and Horowitz
realized that they could not build a 500 MHz
DRAM with current technology and so, to
transmit data at the highest possible speed,
they conceived the idea of transmitting and
receiving data on both edges of a 250 MHz
clock. (Farmwald, Tr. 8118; Horowitz, Tr.
8495-97).
2. Clocking Issues
51. With respect to clocking issues, Drs.
Farmwald and Horowitz realized from per-
sonal experience that, although current mem-
ory chips were asynchronous, they would have
to develop a synchronous device with mech-
anisms for exercising very tight control over
timing with respect to the clock to make sure
that each bit of data — traveling at a very high
speed — was sampled at the right time. (Horo-
witz, Tr. 8488-89; see infra F. 52-53, 284 for
discussion of asynchronous versus synchronous
devices).
52. Drs. Farmwald and Horowitz decided to
design a synchronous system since the timing
reference provided by a clock could be used to
limit timing uncertainties in the system and
allow for high speed performance. (Horowitz,
Tr. 8499-502).
53. Even in a synchronous system there
remain some timing uncertainties; for exam-
ple, expected delays of the buffers may vary
from DRAM to DRAM due to differences in
their fabrication. (Horowitz, Tr. 8503-04). In
order to have the highest speed possible, Drs.
Farmwald and Horowitz wanted to minimize
438a
this remaining uncertainty to the extent pos-
sible; they therefore came up with the idea of
using a delay locked loop (DLL) or a phase
locked loop (PLL) on-chip. (Farmwald, Tr.
8118; Horowitz, Tr. 8504).
3. The Memory Interface Protocol
54. With respect to the design of the pro-
tocol, additional optimizations developed for
high speed operation included returning a
variable amount of data in response to a
request rather than a single bit of data and by
putting registers and associated control cir-
cuitry directly on the DRAM. (Farmwald, Tr.
8115; Horowitz, Tr. 8489-90).
55. With respect to the protocol, Drs. Farm-
wald and Horowitz again came up with various
innovations. As one example, they decided to
put registers on the DRAM to make the
interface more efficient. (Farmwald, Tr. 8115-
16; Horowitz, Tr. 8506). These registers would
be programmed with parameters, such as the
address range that a particular DRAM would
respond to or the access time of the DRAM.
(Horowitz, Tr. 8507, 8509-10). |
56. Drs. Farmwald and Horowitz wanted to
make the access time variable for two reasons.
First, if the bus were improved so that it could
operate at a faster clock frequency, the access
time of the DRAM could be adjusted so that it
would operate with that faster clock. Second, a
variable access time would allow the access
times of all the DRAMs in a system to be ad-
justed to have the same access time. (Horowitz, _
Tr. 8510-11).
439a
57. As another example of an innovation
related to the protocol, Drs. Farmwald and
Horowitz allowed the response to a request to
include a variable amount of data, a feature
known as “variable block size” or “variable
burst length.” (Farmwald, Tr. 8116-17, 8146;
Horowitz, Tr. 8512; RX 82 at 9).
II. RAMBUS: COMPANY DEVELOPMENT AND
PUBLIC PROMOTION OF TECHNOLOGY
A. The Founding of Rambus
58. Drs. Farmwald and Horowitz founded
“Rambus Inc.” in March of 1990. (CX 545 at 5;
RX 81 at 19). By 1992, its headquarters were
located in Mountain View, California, in Sili-
con Valley. (RX 81 at 1, 3).
59. Rambus is, and at all relevant times has
been, a corporation as “corporation” is defined
by Section 4 of the Federal Trade Commission
Act, 15 U.S.C. § 44; and at all relevant times
has been and is now engaged in commerce as
“commerce” is defined in that same provision.
(Answer, {J 5, 6).
60. Rambus designs, develops, licenses, ar.a
markets both nationally and internationally,
high-speed chip connection technology to en-
hance the performance of computers, consumer
electronics, and communications systems. (An-
swer, J 5). Rambus is a pure-play licensing
company; it does not manufacture DRAM, but
rather uses research and development to in-
vent new DRAM technologies and makes its
money by licensing its technology to others.
(Teece, Tr. 10350-51).
440a
61. For the fiscal year that ended on Sep-
tember 30, 2001, Rambus reported revenues of
approximately $117 million. (Comp., J 5; An-
swer, ¥ 5).
62. Rambus’s founders intended to improve
memory performance through multiple invent-
tions based on modifications of standard
DRAMs (see CX 533 at 2), which could be used
separately or in combination(s). The greatest
performance gains would be realized by using
these inventions in combination. Rambus
DRAM or “RDRAM” is the name for the “revo-
lutionary DRAM architecture and high speed
chip-to-chip data transfer technology” that
incorporates several of Rambus’s inventions,
including its proprietary bus technology. (RX
81 at 3). Each of the various generations of
RDRAM are manufactured in accordance with
specifications established through a collabo-
ration among Rambus and its DRAM partners.
(Farmwald, Tr. 8149, 8241).
63. Early on, Rambus realized that it was
important to its business strategy to protect
the intellectual property rights to its tech-
nology. (CX 535 at 1). Part of its early strategy
to do this was to pursue an application for “a
basic, broad patent filed in all major industrial
nations” and thereafter “follow up with addi-
tional patents on inventions created during the
development of the technology.” (CX 535 at 1).
It was also important to Rambus to enter into
nondisclosure agreements with companies
exposed to its technology. (CX 535 at 1).
64. The only business model that “made any
sense” to Rambus co-founder Michael Farm-
44la
wald “was to patent [the technology], convince
others to build it, and charge them royalties”
because “[w]hen we were first formed, it was
my view that we could not possibly raise
enough money to build DRAMs. DRAM fabs
cost, even back then they cost, [sic] order of
a billion dollars. You couldn’t really build
DRAMs without owning your own fab, and so a
business plan which involved actually building
and selling DRAMs was hopeless, and so from
the very beginning we were a royalty-based
company.” (Farmwald, Tr. 8095; CX 2106 at 27
(Farmwald, Dep.)).
65. Rambus’s primary objective was to com-
mercialize the revolutionary inventions Drs.
Farmwald and Horowitz had created in the
form of an open industry de facto standard,
and to ensure that the standard “didn’t go off
in incompatible directions.” (Farmwald, Tr.
8110, 8125-26, 8148).
66. Rambus contemplated that it would
earn its income by working with DRAM com-
panies to implement the Rambus interface in
their products, and, for that work, get paid
consulting fees (for the time its engineers
spent working with partners) and royalties for
the use of Rambus’s intellectual property that
would be incorporated into DRAM companies’
products. (Farmwald, Tr. 8150).
67. To become and remain a viable com-
pany, it intended to charge low single digit
royalties, which it believed to be fair in light of
the importance of Rambus’s intellectual prop-
erty contribution to the product and the large
442a
size of the DRAM market. (Farmwald, Tr.
8128; CX 1282 at 5).
68. Rambus founder Farmwald knew that
companies never like to pay royalties unless
they have to and they can not “get out of it.”
(CX 2106 at 27 (Farmwald, Dep.)).
1. Securing Venture Capital Funding
69. In an effort to receive funding for the
start-up of Rambus Inc., the founders ap-
proached various venture capital firms: Klei-
ner Perkins, one of the largest venture capital
firms in the world; Merrill Pickard Anderson
and- Eyre; and Mohr Davidow. (Farmwald,
Tr. 8099). As part of the meetings with the
venture capital firms, the founders prepared
presentations and showed them documents,
such as early business plans. (Farmwald, Tr.
8100). These meetings occurred around the
time of a June 1989 RamBus Business Plan.
(Farmwald, Tr. 8100-01; see CX 533).
70. The start-up had significant financial
considerations and according to the June 1989
business plan, “RamBus” founders (Michael
Farmwald, Mark Horowitz), were able to in-
vest $75,000 in “seed money” and were seeking
an additional $1.5 million in equity invest-
ment. (CX 533 at 4). This amount would only
fund the company through “the completion of a
prototype and to the development of [its] initial
DRAM vendor partnerships.” (CX 533 at 4).
Until it signed with its revenue producing
partners, estimated expenses were $100,000
per month. (CX 533 at 5).
443a
71. In March 1990, Rambus Inc. was born
after receiving venture capital funding of $1.86
million from three firms. (CX 545 at 5; RX 81
at 19).
2. Early Business Plan for’ the
Farmwald/ Horowitz Inventions
72. As a 1989 draft business plan explained,
Farmwald and Horowitz hoped to establish a
de facto standard “by offering all interested
DRAM and central processing unit (“CPU”)
vendors a sufficiently low licensing fee (2%)
that it will not be worth their time and effort
to attempt to circumvent or violate the
patents.” (RX 15 at 9).
73. Dr. Farmwald explained, “{wle were
going to try and find customers for our parts,
big customers, and we were going to try and
license all the DRAM makers to build our part
to supply those customers,” which would lead
to de facto standardization. (Farmwald, Tr.
8124-25).
74. The founders intended to use a program
of phased licensing and promotion of its
proprietary RDRAM technology in order to
convince the industry to adopt its proprietary
technology as the industry standard. (Farm-
wald, Tr. 8297).
75. The plan was for their technology to be
an “open standard”; they refused to license its
technology on exclusive terms. (Farmwald,
Tr. 8185; RX 25 at 16).
76. An “open standard” in the DRAM in-
dustry is a standard for which any patents
4444
that apply to it are available on reasonable and
nondiscriminatory terms. (Bechtelsheim, Tr.
5897; CX 2112 at 190-91 (Mooring Dep.)).
77. Farmwald and Horowitz wanted to
avoid what happened to the Sony Betamax,
which was hampered in the market by re-
strictive licensing. (Farmwald, Tr. 8165-66).
Instead, their goal was to license the tech-
nology “openly and fairly to everybody so
everyone is on equal footing with a relatively
low royalty.” (Farmwald, Tr. 8165-66).
78. Their early business plans indicate that
they were aware that it would be necessary
early on to charge lower royalties in order to
foster acceptance of their proprietary tech-
nology. They recognized that there was a
“trade-off of royalty size vs. incentive to de-
velop alternatives” to their technology. (CX 533
at 14).
79. To ensure that the Farmwald/Horowitz
technology was standardized, i.e., that parts
from one manufacturer were interchangeable
with parts from another manufacturer, the
inventors planned to cooperate with their part-
ners (i.e., the licensees who would manufacture
the devices) to ensure that feedback was
propagated to all partners so that everyone
would use the same good ideas instead of cre-
ating customized parts. (Farmwald, Tr. 8148;
see RX 82 at 17).
80. Farmwald and Horowitz believed that
they had compelling, revolutionary ideas, that
their patents would be significant, and that a
small royalty would be palatable given the per-
445a
formance leap of the technology. (Farmwald,
Tr. 8112-13).
81. The key to success for Farmwald and
Horowitz was that they “had to find a number
of high-volume customers and high-volume
producers to produce the part so that it became
the part that everybody was using” in order for
their technology to become a de facto standard.
(Farmwald, Tr. 8140; CX 1750 at 1).
82. To this end, the inventions were de-
signed to be produced using existing DRAM
manufacturing technology. (Farmwald, Tr.
8142-43; RX 82 at 6).
B. The RDRAM Technology
83. Because from the start the founders
believed that “[rJoyalties are the lifeblood of
Rambus” (CX 2106 at 221 (Farmwald, Dep.)),
Rambus placed great importance on promoting
and protecting its proprietary technology. The
Rambus founders “felt we had a very sig-
nificant invention. We felt that the only way to
protect and to extract vaiue from that inven-
tion was to patent it.” (CX 2106 at 28 (Farm-
wald, Dep.)).
84. Rambus saw its proprietary Rambus
DRAM (“RDRAM”) technology as _ offering
dramatic improvements over existing memory
technology of the time. In 1992 it claimed that
RDRAM technology “achieves a ten-fold in-
crease in component throughput” and would
result in “dramatically increasing system
price/performance.” (RX 81 at 3). In addition,
Rambus claimed that use of the RDRAM
technology “assures a smaller system with
446a
fewer components, and provides the user with
a modular, scalable solution.” (RX 81 at 3).
85. The high-speed chip-to-chip data trans-
fer RDRAM technology was intended to be
used not only in memory chips themselves, but
also to be implemented in other chips including
memory controllers, processors, graphics/video
chips and other high performance components
used in virtually every computer system. (RX
81 at 3). The proprietary Rambus technology
was targeted at mainstream applications from
consumer digital video products to desktop
computers and graphics up to massively par-
allel computers. (RX 81 at 3).
86. The RDRAM technology in the early
1990’s included numerous inventions relating
to the bus, the interface between the bus and
computer chips, and the DRAM. The 1992 Cor-
porate Backgrounder makes clear that the
Rambus “solution is comprised of three main
elements: the Rambus Channel, the Rambus
Interface, and the RDRAM.” (RX 81 at 6). The
Rambus Channel refers to the bus, while the
Rambus Interface and RDRAM refer to other
Rambus innovations separate from the bus.
(RX 81 at 7). Each of these elements contain a
number of independent inventions. (RX 81 at
8-11).
87. RDRAM narrow bus technology contem-
plates the use of circuitry on the chips at either
end of the bus connection to optimize the
signals flowing across the connection. (Horo-
witz, Tr. 8488-90). This circuitry contains high-
level logic which implements a protocol for the
447a
chip-to-chip information transfer. (Horowitz,
Tr. 8489-90).
88. One of the ways that RDRAM tech-
nology achieves a high-speed data transfer
over the narrow bus is through “multiplexing,”
which means that the bus can carry different
pieces of information at different points in
time. (Horowitz, Tr. 8620-21). This aspect of
the RDRAM interface protocol means that over
several clock cycies the bus can carry a combi-
nation of address and control and data signals
on one or more of the same bus lines. (Horo-
witz, Tr. 8620-21; see Rhoden, Tr. 402-03).
89. Another aspect of the RDRAM technol-
ogy is the use of a “packetized” data transfer
protocol. (Horowitz, Tr. 8621; Rhoden, Tr.
403-05). This term means that information
is bundled and the bundle may be sent over
multiple clock cycles rather than transmitted
all at once. (Jacob, Tr. 5465; Rhoden, Tr. 403-
04).
90. The RDRAM technology also contains
various other distinctive aspects, including a
clocking system, sometimes referred to as a
loop clock, to assist in controlling the syn-
chronization of the data transfer between chips
(Rhoden, Tr. 404; Horowitz, Tr. 8647), and a
method of physically packaging the RDRAM
memory chips so that multiple chips could be
vertically mounted on one another to occupy a
small space. (Horowitz, Tr. 8623).
91. The RDRAM technology was sufficiently
distinctive that it was widely considered “revo-
lutionary” in the industry and was promoted
448a
as such by Rambus. (Horowitz, Tr. 8571;
Gross, Tr. 2291; Heye, Tr. 5686-87).
C. The 1990 Business Plan
92. Early Rambus investors were informed
that “[t]he primary business of the RamBus
Company” would be to license proprietary
technology “to manufacturers of DRAM chips
and microprocessors”; that “[t]he DRAM mar-
ket is ... highly sensitized to the concept of
standardization”; and that market conditions
were such that there is “the ability to set world
wide standards for the next generation of
DRAM chips and memory systems.” (CX 533
at 9).
93. The purpose of this early draft of its
business plan was to encourage investment by
explaining to investors why Rambus’s technol-
ogy would enable Rambus to be successful in
the existing and future DRAM market. (See
generally CX 533 at 9-10).
94. Investors were told that “the patented
RamBus technology .. . has the opportunity to
establish a single high performance DRAM
standard,” that in part due to “[t}he DRAM
industry’s penchent [sic] for standardization,”
once the Rambus technology was licensed to
“all major vendors,” it would be “extremely
unlikely that any potential competitor would
be able to gain critical mass enough to chal-
lenge” Rambus; and that such considerations,
including the existence of “strong barriers
to entry” restraining “potential competitors,”
made Rambus an “exceptionally attractive
investment opportunity.” (CX 533 at 9).
449a
95. The strength of Rambus’s_ business
model depended also on the strength of its
technological innovations. Indeed, Rambus’s
early filed broad patent application and the
advantage its technology was seen to enjoy by
virtue of being “faster, denser, lower power and
cheaper than any other approach” were touted
to investors as the most significant barriers to
entry for potential, follow-on competitors. (CX
533 at 9). It was the “stiff competition” pre-
sented by Rambus innovative technology as
well as its marketing strategy of licensing all
of the major vendors that it claimed made it
less pervious to competitors than other poten-
tial investment opportunities. (CX 533 at 9):
96. Rambus hired its first (and to date only)
Chief Executive Officer — Geoffrey Tate — who
joined Rambus in May 1990. (CX 545 at 5).
D. RDRAM Promotion and _ Licensing
Strategy
97. By November 1990, Rambus had begun
its efforts to promote and protect its tech-
nology. (CX 535 at 4-5). At that date Rambus
had filed for, but not yet obtained, a base
patent on its technology (CX 535 at 3) and had
entered into license contracts that compelled
partners to use Rambus technology patents
and trade secrets only for use in RDRAM-
compatible chips. (CX 535 at 4-5).
98. By June 1992, Rambus had signed tech-
nology license agreements with NEC Corp.
(“NEC”), Toshiba Corp. (“Toshiba”), and Fu-
jitsu Laboratories, Ltd. (“Fujitsu”). (CX 543A
at 11). By January 1994, Rambus had signed
450a
license agreements with Hitachi, Ltd. (“Hi-
tachi”), Oki Electric Industry Co. (“Oki”),
Lucky Goldstar, and Intel. (CX 547 at 12).
These agreements invoived substantial inter-
action between Rambus and the licensees.
(Farmwald, Tr. 8241).
99. In the course of negotiating with DRAM
manufacturers and others, Rambus encoun-
tered resistence to its business model, and
specifically to royalties. (CX 711 at 13, 61). “A
few systems companies and IC [integrated
circuit] companies have had a very negative
reaction to our business model. Some believe
that it is not ‘fair’ that we are wanting to
charge a royalty on ICs that incorperate our
technology. Others believe our royalty will
make ICS incorporating our technology ‘too
expensive.’ Two specific examples are Sun and
Tseng.” (CX 543A at 14).
100. Rambus limited the use of its license
agreements to so-called RDRAM compatible
uses only. Most companies accepted this term.
Samsung Electronics Co., Ltd. (“Samsung”),
however, insisted on an agreement without
field of use restrictions. (CX 767).
101. In 1994, Samsung recognized that
Rambus’s inventions could be used in non-
compatible Rambus parts, i.e. in parts without
Rambus’s proprietary bus technology. (CX
767). Moreover, Rambus made it clear to
Samsung that Rambus’s intellectual property
rights were not limited to the RDRAM product.
(CX 2078 at 116 (Karp, Dep.)).

E. Presentation of the Rambus Inventions
to the DRAM Industry
1. Rambus Visits to DRAM Manu-
facturers and Systems Companies
102. In 1989-90, Drs. Farmwald and Horo-
witz made visits to many DRAM manufac-
turers and systems companies to try to con-
vince them about the benefits of their approach
and to get feedback from them. (Horowitz, Tr.
8515).
103. Among the DRAM manufacturers that
Drs. Farmwald and Horowitz visited in 1989-
90 were Texas Instruments, IBM, Toshiba,
Fujitsu, Mitsubishi Electric Corp. (“Mitsu-
bishi”), NEC, Matsushita Elect. Indus. Co.,
Ltd. (“Matsushita”), Micron, and Siemens
(whose former semiconductor division is now
Infineon Technologies). (Horowitz, Tr. 8515;
Farmwald, Tr. 8166).
104. Among the systems companies that Drs.
Farmwald and Horowitz visited in 1989-90
were IBM (both a DRAM manufacturer and a
systems company), Sun Microsystems (“Sun”),
Motorola, Apple Computer (“Apple”), SGI, and
Tandem. (Horowitz, Tr. 8515; Farmwald, Tr.
8166-67).
105. The response to the early presentations
in 1989-90 was “just disbelief” that Drs. Farm-
wald and Horowitz would be able to achieve a
500 megabit per second DRAM data rate.
(Horowitz, Tr. 8516). People who listened to
these presentations were also skeptical about
many of the specific features of the technology.
For example, it was felt that putting registers
452a
on a DRAM was too expensive for a commodity
part and that one could not put a phase locked
loop or a delay locked loop on the DRAM itself.
(Horowitz, Tr. 8517).
106. The four inventions at issue in this case
were described in these early presentations.
For example, one of the early presentations
that Dr. Horowitz gave, with slides dated
January 31, 1990, states that the Rambus
interface “allows ‘block mode’ transfer from an
individual DRAM” with “1-1024 byte long
blocks supported.” (RX 29 at 9; Horowitz, Tr.
8518-20). This describes variable block size or
variable burst length. (Horowitz, Tr. 8520).
107. The January 31, 1990 presentation also
describes the use of a delay locked loop on the
DRAM to reduce clock skew. (RX 29 at 33-34;
Horowitz, Tr. 8521-22).
108. The January 31, 1990 presentation also
refers to the dual-edge clock or double data
rate technique. (RX 29 at 34; Horowitz, Tr.
8522-23).
2. Preparation and Description of the
Rambus Inventions Through Various
Technical Publications
109. In the 1990-91 period, Dr. Horowitz
prepared detailed technical descriptions of
the Rambus technology. (Horowitz, Tr. 8523).
These documents were for Rambus’s internal
use and were also used with customers and
potential customers to convince them of the
merits of Rambus technology and to help them
build it. (Horowitz, Tr. 8523-24). These docu-
ments disclose all four of the relevant product
453a
markets in this case: dual-edge clocking, on-
chip DLL, programmable CAS latency, and
programmable burst length.
a. The May 1990 Technical
Description
110. One of these technical descriptions is
dated May 7, 1990 and was generated at about
that time. (RX 63; Farmwald, Tr. 8168-69;
Horowitz, Tr. 8524-25).
111. The May 7, 1990 technical description
described all four of the technological features
at issue in this case. (Horovitz, Tr. 8525-29).
112. For example, the technical description
described dual-edge clocking in a figure with
two input receivers, one clocked by a signal
designated “CLK” (clock) and the other clocked
by the complement of CLK (clock bar), a signal
that is zero when clock is one and vice versa.
(RX 63 at 10; Horowitz, Tr. 8525-26). This
means that one receiver samples an input
when the clock goes high (the rising edge of the
clock) and the other when the clock goes low
(the falling edge). (Horowitz, Tr. 8526).
113. The May 7, 1990 technical description
also described a delay-locked loop on the
DRAM (on-chip DLL feature). (Horowitz, Tr.
8527-28). A figure in the technical description
shows two delay locked loops generating the
internal clocks for Rambus’s design. (RX 63 at
14; Horowitz, Tr. 8527).
114. The May 7, 1990 technical description
also described programmable latency. (Horo-
witz, Tr. 8528). In the “device registers” section
454a
of the document, an “access time” or latency
register is listed. (RX 63 at 18; Horowitz, Tr.
8528). “Latency” refers to the time between
request and response. (Horowitz, Tr. 8530).
The document explains that a fixed value for
latency “does not allow for technology improve-
ments,” and, consequently, the Rambus system
“set[s] the time between request and response
during system reset.” (RX 63 at 5-6; Horowitz,
Tr. 8530-31). In other words, the value in the
access time or latency register would be fixed
when the system was started up and probably
would not be changed after that time. (Horo-
witz, Tr. 8531).
115. The May 7, 1990 technical description
also described variable burst length. (Horo-
witz, Tr. 8528-29). The document contains a
table showing a variable number of bytes in
the block size or burst length depending on the
value in the “BlockType” field. (RX 63 at 21;
Horowitz, Tr. 8528-29).
b. The November 1990 Technical
Description
116. A later Rambus technical description,
dated November 5, 1990, was’ generated
around that time. (RX 94; Farmwald, Tr. 8169;
Horowitz, Tr. 8535).
117. The November 5, 1990 technical de-
scription was sent to Siemens (now Infineon).
(RX 99; Farmwald, Tr. 8169-70).
118. The November 5, 1990 technical de-
scription described dual-edged clocking. First,
the document contains the same figure relating
to inputting data on both edges of the clock as
455a
in the May 7, 1990 description. (RX 63 at 10;
RX 94 at 15; Horowitz, Tr. at 8535-36). Second,
the document shows that the output data is
also being transmitted on both edges of the
clock. (RX 94 at 19; Horowitz, Tr. 8536).
119. The November 5, 1990 technical de-
scription described two alternatives for the
DRAM clock circuitry. One alternative was to
use a phase locked loop. (RX 94 at 45; Horo-
witz, Tr. 8536-37). The other alternative was to
use delay locked loops. (RX 94 at 46; Horowitz,
Tr. 8537).
120. The November 5, 1990 technical de-
scription described variable latency using a
data delay field in the request packet. (RX 94
at 59; Horowitz, Tr. 8537-38).
121. The November 5, 1990 technical de-
scription described variable block size or burst
length with a table similar to that in the May
7, 1990 technical description. (RX 63 at 21; RX
94 at 60; Horowitz, Tr. at 8538).
c. Siemens Responds With a List of
Questions About Rambus Tech-
nology
122. Both Dr. Farmwald and Dr. Horowitz
received feedback from Siemens regarding the
November 5, 1990 technical description. (RX
102; RX 117; Farmwald, Tr. 8171-72; Horowitz,
Tr. 8541-42).
123. A fax from K. Horninger of Siemens to
Dr. Farmwald, dated December 7, 1990, con-
tained a detailed list of questions relating to
456a
the November 5, 1990 technical description.
(RX 102; Farmwald, Tr. 8171-73).
124. A fax from H.J. Neubauer of Siemens to
Dr. Horowitz, dated January 29, 1991, stated
“Dear Dr. Horowitz, concerning the RAMBUS
Technical Description some basic items re-
mained open. In the following we present a list
of detailed questions to you which we would
like to get answered.” (RX 117 at 2; Horowitz,
Tr. 8542).
125. A number of the questions in the fax
that Siemens sent to Dr. Horowitz related to
the four features of Rambus technology at
issue in this case. (See RX 117).
126. Question number one in the Siemens
fax asked about the details of how eight bits of
data would be transmitted by the DRAM and
relates to Rambus’s variable block size feature.
(RX 117 at 2; Horowitz, Tr. 8543-44).
127. Question number two in the Siemens
fax asked about the implementation of variable
latency in the Rambus technology. (RX 117 at
2; Horowitz, Tr. 8544).
128. Another question in the Siemens fax
referenced Figure 13 on internal page 14 of the
November 5, 1990 technical description. (RX
117 at 4). That figure showed dual-edge clock-
ing or double data rate on the output. Dr.
Horowitz’s understanding was that Siemens’s
question related to the implementation of
the double data rate drivers as shown in the
November 5, 1990 technical description. (RX
94 at 19; RX 117 at 4; Horowitz, Tr. 8546).
457a
129. Another question in the Siemens fax
referenced Figure 28 on internal page 41 of the
November 5, 1990 technical description. (RX
117 at 4). That figure shows a delay locked
loop and Siemens’s question was about the
delay locked loop. (RX 94 at 46; RX 117 at 4;
Horowitz, Tr. 8546).
d. The April 1991 #£Technical
Description
130. A still later Rambus technical de-
scription was released on April 1, 1991 and
was a more complete version with many more
technical details. (RX 130; Farmwald, Tr. 8171;
Horowitz, Tr. 8538).
131. The April 1, 1991 technical description
described dual-edged clocking. (RX 130 at 36;
Horowitz, Tr. at 8539).
132. The April 1, 1991 technical description
described using a phase locked loop on the
DRAM. (RX 130 at 56; Horowitz, Tr. 8539).
133. The April 1, 1991 technical description
described programmable latency through the
use of a “read delay” or latency register. (RX
130 at 94; Horowitz, Tr. 8539-40).
134. The April 1, 1991 technical description
described variable block size or burst length,
with the value in a “count” field representing
the number of bytes to be transferred. (RX 130
at 64; Horowitz, Tr. at 8539).
F. The March 1992 Press Events
135. On March 9, 1992, Rambus held simul-
taneous events in the Silicon Valley and in
Tokyo to publicly announce its technology and
458a
its business plan. (Farmwald, Tr. 8182-84;
RX 67 at 1). Prior to this date, Rambus had
presented its technology to companies on an
individual basis and had secured licenses from
three of the top five DRAM manufacturers:
Fujitsu, NEC, and Toshiba. (RX 67 at 2).
136. The press release announcing these
events stated that Rambus’s_ revolutionary
technology would offer a tenfold improvement
over traditional DRAMs and would solve the
memory bottleneck. (RX 67 at 1). The press
release also described Rambus’s business plan
as licensing its technology in return for license
fees and royalties. (RX 67 at 2). By controlling
the Rambus interface standard, Rambus would
ensure compatibility. (RX 67 at 2). The press
release also made it clear that Rambus’s “open
standard” would be “available for license by
any IC [Integrated Circuit] company.” (RX 67
at 2; see also Farmwald, Tr. 8185).
137. At the events, Rambus made available a
“Corporate Backgrounder” that provided an
overview of Rambus’s business strategy and its
technology. (RX 81; Farmwald, Tr. 8186). The
Backgrounder explicitiy detailed Rambus’s in-
tellectual property strategy: “Rambus Inc. is
fully protecting the intellectual property rights
of its technolegy by filing basic, broad patents
in all major industrial nations around the
world.” (RX 81 at 3).
138. Later in this same public document,
there are descriptions of Rambus’s technology.
(RX 81 at 8-11). The Backgrounder states
that Rambus’s “dramatic performance im-
provements were achieved through numerous
459a
technical breakthroughs” and then proceeds to
describe “[s]ome of the major technical high-
lights of the Rambus solution.” (RX 81 at 8).
The technology descriptions included the use of
dual-edge clocking: “[a]n innovative electrical
interface permits the Rambus Channel to oper-
ate at 500 Megabytes/second by using both
edges of a 250 MHz clock.” (RX 81 at 8).
Moreover, the technology descriptions explic-
itly state that Rambus used the on-chip
PLL/DLL technology: “[c]lock skew and capa-
citive loading are minimized by a phase lock
loop circuit on board both the master and the
RDRAM.” (RX 81 at 8).
139. The Backgrounder also made it clear
that Rambus’s technology was divided into
three distinct elements of the memory system:
the Rambus Channel (the high-speed bus); the
Rambus Interface (the circuitry that connects a
device, such as a controller or DRAM, to the
bus); and the Rambus DRAM (the memory
itself). (RX 81 at 7; Farmwald, Tr. 8188-90).
140. The Backgrounder also stated that
Rambus’s business strategy was to license its
technology, work with the licensee to help
implement the technology, and to receive fees
and royalties in return. (RX 81 at 3; see also
Farmwald, Tr. 8186-87).
141. Later that year, at the invitation of
Betty Prince, a long-time consultant in the
DRAM industry (Prince, Tr. 8970-72, 8986-87),
Dr. Farmwald and David Mooring of Rambus
published an article in the October 1992 issue
of IEEE Spectrum, which gave a brief de-
scription of the Rambus technology and stated
460a
that the “technology behind the architecture
can be licensed for a royalty fee comparable to
that for other patented technologies.” (RX 332
at 1).
142. During the early 1990’s Rambus’s busi-
ness model was well known in the industry.
Brett Williams, a JEDEC Solid State Tech-
nology Association (“JEDEC”) representative
for Micron testified that in 1992, “I knew it
was [Rambus’s] business model to patent their
technology, and that’s how they would gain
their revenues.” (Williams, Tr. 857). Similarly,
Martin Peis] of Infineon stated that he was
aware of Rambus’s business model in the early
1990’s and expected Rambus to get patents to
cover its technology. (Peisl, Tr. 4505).
143. According to Andreas Bechtelsheim,
formerly of Sun Microsystems, Rambus made
very clear to Sun that it intended to seek
patent coverage for all of its inventions and
developments, and Rambus explained to vari-
ous companies, including Sun, that it was seek
ing patent coverage for its inventions because
it intended to obtain revenue or earn revenue
through licensing its technology to both mem-
ory manufacturers and system manufacturers.
(Bechtelsheim, Tr. 5819).
G. Press Coverage: The March 1992
Microprocessor Report Article
144. In connection with the public announce-
ment of Rambus’s technology and its business
plan in March 1992, Rambus provided infor-
mation to the press regarding Rambus’s inven-
46la
tions, and numerous articles about Rambus
appeared. (RX 1446).
145. Many of these articles provided a sig-
nificant amount of technical detail. For exam-
ple, an article entitled “Rambus Unveils Revo-
lutionary Memory Interface” in the March 4,
1992 Microprocessor Report describes Ram-
bus’s technology in some depth and described
three of the four features of Rambus technol-
ogy at issue here, as well as aspects of the
fourth. (RX 1446 at 22-26).
146. The article states that the “Rambus
Channel is a 500-Mbyte/s interface, operating
with a 250-MHz clock and transferring a byte
of data on each clock edge” and that a “phase-
locked loop on each Rambus device limits clock
skew within the chip.” (RX 1446 at 22, 23).
147. The article also states that the “six-byte
request packet encodes a 36-bit address, a 4-bit
operation code, and 8-bit transfer length count
(in bytes). Byte addressing and block sizes of
up to 256 bytes are supported.” (RX 1446
at 24).
148. The article also notes that “control
registers” on the DRAM can be used to specify
certain parameters. (RX 1446 at 23).
H. Rambus’s Disclosure of Inventions
Through Public Documents
1. The 1992 Marketing Brochure
149. In early 1992, Rambus produced and
distributed its first marketing brochure about
Rambus technology. (RX 2183; Horowitz, Tr.
8547). The 1992 marketing brochure describes
462a
the four features of Rambus technology at
issue here. (Horowitz, Tr. 8547-48).
150. The 1992 marketing brochure states
that the “heart of [the Rambus] Interface is
high performance PLL (phase-locked-loop) cir-
cuitry which provides the clocks for trans-
mitting and receiving Rambus Channel data.”
(RX 2183 at 6).
151. The 1992 marketing brochure describes
variable burst length, because data transfers
could involve a variable amount of data, indi-
cating: “[t]ransfers of 1 to 256 Bytes per Re-
quest.” (RX 2183 at 7).
152. The 1992 marketing brochure describes
dual-edge clocking, stating that “[dJata effec-
tively transferred on both edges of the clock.”
(RX 2183 at 9).
153. The 1992 marketing brochure describes
programmable latency, stating that “the Read
Data Packet is returned a time ReadDelay
after the Request Packet” and that this delay
value is “programmed into the configuration
registers of all devices during system initial-
ization.” (RX 2183 at 11).
2. Publications Describing the First
Rambus DRAM
154. The first Rambus DRAM was a 4.5
megabit Rambus DRAM produced by Toshiba
in the 1991-92 time frame. (Horowitz, Tr.
8548-49).
155. A paper about the Toshiba 4.5 megabit
Rambus DRAM was presented at the 1992
International Symposium on VLSI Circuits
463a
(VLSI Circuits Symposium) and published in
the proceedings of that symposium. (RX 301 at
76-77; Horowitz, Tr. 8552-54).
156. The VLSI Circuits Symposium is held
annually and is one of the top two conferences
in the world for circuit designers. (Horowitz,
Tr. 8552). The “technical program committees”
of the Symposium read all the papers sub-
mitted and choose the better ones for pub-
lication at the conference. (Horowitz, Tr. 8552-
53). The technical program committees for the
1992 VLSI Circuits Symposium that selected
the paper about the Toshiba 4.5 megabit Ram-
bus DRAM included representatives from IBM;
Texas Instruments; Siemens AG; Sun Micro-
systems; Intel; Hitachi; Samsung; Matsushita;
Mitsubishi; Fujitsu Laboratories, Ltd.; Sanyo
Electric Co., Ltd.; Oki; and NEC. (RX 301 at 5).
157. The paper published in the proceedings
of the 1992 VLSI Circuits Symposium about
the Toshiba 4.5 megabit Rambus DRAM dis-
cusses the four features of Rambus technology
at issue in this case. (Horowitz, Tr. 8554).
Figure 2 of the paper shows a block size trans-
fer and read latency. (RX 301 at 77; Horowitz,
Tr. 8555). Figure 3 of the paper shows double
data rate input receivers. (RX 301 at 77;
Horowitz, Tr. 8555). The paper also states that
“(tlo eliminate skew caused by the internal cir-
cuitry, the DRAM contains two PLLs.” (RX 301
at 76; Horowitz, Tr. 8555).
158. At the end of the 1992 VLSI Circuits
Symposium, the authors of the top papers were
invited to provide a longer version to be pub-
lished in the Journal of Solid State Circuits.
464a
(Horowitz, Tr. 8555-56). The Journal of Solid
State Circuits is the most widely read journal
for circuit-designers. (Horowitz, Tr. 8555-56).
The paper about the Toshiba 4.5 megabit Ram-
bus DRAM was selected, and a longer version
of that paper was published in the Journal of
Solid State Circuits in April 1993. (RX 385;
Horowitz, Tr. 8556).
I. Presentations of the Proprietary
RDRAM Technology and Nondisclo-
sure Agreements
159. Continuing for many years, Rambus
pursued a strategy of actively promoting its
proprietary RDRAM technology to companies
that were in a position to manufacture memory
chips or related chipsets. Rambus also pro-
moted RDRAM to others, including systems
companies. (See Crisp, Tr. 2931; CX 543A at 1,
3, 7-8).
160. Rambus’s efforts to promote adoption of
its proprietary RDRAM technology included
making presentations concerning the proprie-
tary RDRAM technology to memory chip man-
ufacturers and other firms. (E.g. CX 2107 at 63
(Oh, Dep.); Bechtelsheim, Tr. 5818-19; Kellogg,
Tr. 5052-53).
161. In connection with such efforts, Rambus
commonly entered into nondisclosure agree-
ments that prohibited the firms from disclosing
information concerning the proprietary Ram-
bus technology to others without the consent of
Rambus. (Bechtelsheim, Tr. 5818-19; Rhoden,
Tr. 521; Kellogg, Tr. 5052-53). Rambus’s pres-
entations often included a discussion of the
465a
patent protection Rambus was seeking for its
inventions. (CX 2079 at 83 (Mooring, Dep.); CX
2111 at 314-15, 316-18, 319-20, 320-21, 322-24
(Tate, Dep.)).
162. In April 1992, Gordon Kelley of IBM
attended a presentation by Rambus at IBM
comparing the proprietary Rambus RDRAM
technology with Synchronous Dynamic Ran-
dom Access Memory (“SDRAM”). (G. Kelley,
Tr. 2535).
163. Desi Rhoden was employed at Hewlett-
Packard (“HP”) when he began to learn about
the Rambus technology in the early 90’s.
(Rhoden, Tr. 396). Rambus came to HP to give
a presentation about its new memory that it
was developing. (Rhoden, Tr: 396). The presen-
tation was made pursuant to a nondisclosure
agreement between Rambus and HP. (Rhoden,
Tr. 521). Although Rambus did not say any-
thing at that presentation about pending
Rambus patent applications, Rhoden assumed
that Rambus probably did have patent appli-
cations. (Rhoden, Tr. 521).
164. Andreas Bechtelsheim, a Vice-President
for technology at Sun (Bechtelsheim, Tr. 5752),
was involved in presentations and discussions
with Rambus and understood that Rambus
had patent rights that covered its proprietary
RDRAM technology. (Bechtelsheim, Tr. 5828-
29; 5841-42). Rambus “made clear [to Bechtel-
sheim] that they were going to protect any
patent on their memory technology because
that was their business model.” (Bechtelsheim,
Tr. 5829).
466a
165. Mark Kellogg, an employee of IBM,
learned about Rambus technology through a
presentation by Rambus to IBM in the early
1990’s. (Kellogg, Tr. 5017, 5052-53).
166. Terry Lee, an employee at Micron,
learned about Rambus technology in part from
a meeting with Rambus held in 1995. (Lee, Tr.
6601-02). Following the meeting, he and a
colleague, Kevin Ryan, reviewed selected pa-
tent abstracts. (Lee, Tr. at 6607-08). Lee con-
cluded that the patents appeared to apply
specifically to the RDRAM bus structure. (Lee,
Tr. at 6610-11). In March of 1997, Lee ex-
pressed concerns to the JEDEC JC 42.3 com-
mittee that a double data rate SDRAM (“DDR
SDRAM”) presentation “looked like” one of the
Rambus patents he had reviewed in 1995.
(Lee, Tr. 6956-59).
J. The June 1992 Business Plan
167. By June 1992, Rambus CEO Geoffrey
Tate transmitted to the Rambus Board of
Directors a comprehensive five-year business
plan, which, he explained, was based on “in-
puts from ail of the executives.” (CX 543A
at 1). As reflected in the “Executive Summary”
of this June 1992 Business Plan, Rambus’s
strategy was to:
develop a breakthrough technology with
high value added in a large percentage of
computer, communications, and consumer
digital systems products;
establish strong intellectual property bar-
riers; ...
467a
to license the technology for integration
onto high volume ICs of all major IC com-
panies and to have license fees cover the
costs of technology and market develop-
ment;
to establish Rambus as the new interface
standard for systems requiring high per-
formance at low cost; .. .
to establish a very high profit stream of
technology royalties; [and]
to continually improve on Rambus Tech-
nology through minor and major enhance-
ments....
(CX 543A at 3).
K. Rambus Patent Applications
1. The ‘898 Patent Application
168. Rambus filed patent application serial
no. 07/510,898 (the ‘898 application) in the
United States Patent and Trademark Office
(“PTO”) on April 18, 1990. (CX 1451 at 1-2;
Nusbaum, Tr. 1507). The ‘898 patent appli-
cation included a descriptive portion, called the
“specification,” that was sixty-two pages long,
and included fifteen original drawings. (CX
1451 at 3-63, 140-50). The ‘898 patent appli-
cation contained one-hundred fifty claims. (CX
1451 at 64-125).
169. In connection with the prosecution of
its ‘898 patent application, Rambus was issued
a communication by the patent examiner at
the PTO containing a restriction requirement.
(Nusbaum, Tr. 1511).
468a
170. A restriction requirement reflects that
the examiner has reviewed the application and
determined that the application contains
claims describing multiple “independent and
distinct inventions.” The applicant is required
to elect which of the claimed inventions it
wishes to pursue in the application. (Nusbaum,
Tr. 1510).
171. The restriction requirement received by
Rambus was an eleven-way restriction require-
ment; Rambus responded by restricting its
original application and filing ten divisional
patent applications on March 5, 1992, all of
which claimed priority based on the filing date
of the original ‘898 application, April 18, 1990
(Nusbaum, Tr. 1511-12; First Set of Stipula-
tions, Stip. 22).
172. Over time, Rambus filed numerous
additional continuation and divisional patent
applications claiming priority based on the
filing date of the original ‘898 application. (See
First Set of Stipulations, Stip. 22).
173. Prior to June 1996, Rambus filed a total
of seventeen continuation and divisional pa-
tent applications claiming priority based on
the filing date of the original ‘898 application,
and had been issued six United States patents
on such applications. (First Set of Stipulations,
Stip. 22).
174. As of April 2003, Rambus had filed
sixty-three continuation and divisional patent
applications claiming priority based on the
filing date of the original ‘898 application, of
469a
which ten were still pending. (First Set of
Stipulations, Stip. 22).
175. As of April 2003, at least 43 United
States patents had been issued to Rambus
from continuation and divisional applications
claiming priority to the original ‘898 appli-
cation. (First Set of Stipulations, Stip. 13).
176. Over time, various of the Rambus
continuation and divisional patent applications
claiming priority to the ‘898 application em-
bodied changes and amendments to the claims
made in the original ‘898 application and came
to describe aspects of the original invention.
(See, e.g., Crisp, Tr. 2927-28).
177. The patents that Rambus has asserted
against DRAM manufacturers have all issued
from applications that are continuations or
divisionals stemming from the original ‘898
application and all share a specification with
that original application. (First Set of Stipu-
lations, Stip. 22; Nusbaum, Tr. 1513-14).
178. Pursuant to the “written description”
requirement for a patent’s validity, the PTO
determined that the claims of these patents
were supported by the specification of the orig-
inal ‘898 application. (Nusbaum, Tr. 1611-14).
2. The ‘703 Patent
179. Rambus’s first United States patent,
U.S. Patent No. 5,243,703 (“the ‘703 patent”),
issued on September 7, 1993. (RX 425). Ram-
bus disclosed the ‘703 patent to JEDEC during
a committee meeting in September 1993. (First
Set of Stipulations, Stip. 11). The ‘703 patent
470a
was subsequently added to the “patent track-
ing list” maintained by JEDEC, where it was
described as involving a “Sync Clock.” (JX 18
at 18).
180. The “703 patent can be traced back to a
divisional application of the original ‘898 ap-
plication. (RX 425 at 1; Fliesler, Tr. 8812).
181. The written description and drawings of
the ‘703 patent, like all the issued patents that
claim priority to the ‘898 application, are sub-
stantially the same as the written description
and drawings in the ‘898 application. (RX 425
at 1; CX 1451 at 1; Fliesler, Tr. 8812, 8817).
Thus, the “703 patent contains the same de-
scriptions of technologies as in the ‘898 appli-
cation and PCT application. (RX 425 at 7, 8, 9,
14-17, 21; Fliesler, Tr. 8819-20).
182. In addition to listing the original ‘898
application, the “703 patent’s written descrip-
tion also contains a list of the nine other
divisional applications stemming from the ‘898
application that were pending at the time. (RX
425 at 11; Fliesler, Tr. 8813-14).
3. The PCT Application
183. On April 16, 1991, Rambus filed an
international patent application pursuant to
the Patent Cooperation Treaty (the “PCT
application”). (CX 1454 at 1).
184. The PCT application is identical in all
material respects to the ‘898 application. In
particular, the PCT application contains the
same written description, drawings, and
47la
claims as the ‘898 application. (CX 1451; CX
1454; Fliesler, Tr. 8811).
185. The PCT application was published and
made publicly available as of October 31, 1991.
(CX 1454 at 1; First Set of Stipulations, Stip.
8). Several JEDEC members obtained the PCT
application in the early 1990’s, including Mit-
subishi and IBM. (RX 379A at 1; RX 201 at 1).
4. The ‘898 and PCT Applications
Describe Numerous Inventions
186. The ‘898 and PCT applications each
contain a lengthy disclosure consisting of a
sixty-two page written description, fifteen
drawings, and one hundred and fifty claims.
(CX 1451, CX 1454).
187. The written description of the ‘898 and
PCT applications contain numerous headings
and subheadings, such as “Device Address
Mapping,” “Bus,” “Protocol and Bus Opera-
tion,” “Retry Format,” “Bus Arbitration,” “Sys-
tem Configuration/Reset,” “ECC,” “Low Power
3-D Packaging,” “Bus Electrical Description,”
“Clocking,” “Device Interface,” “Electrical In-
terface - Input/Output Circuitry,” and “DRAM
Column Access Modification.” (CX 1451 at 18,
20, 21, 30, 32, 37, 40, 43, 45, 47, 54; CX 1454 at
18, 20, 21, 30, 32, 37, 41, 44, 46, 48, 55).
188. Although the applications describe how
an entire system is to be put together, they
also describe numerous technical features that
can be used independently of one another and
of the system. (Fliesler, Tr. 8788-89).
472a
189. The ‘898 and PCT applications note
that, although a preferred implementation of
the invention contains 8 bus data lines, “[p]er-
sons skilled in the art will recognize that 16
bus data lines or other numbers of bus data
lines can be used to implement the teaching
of this invention.” (CX 1451 at 10; CX 1454
at 10).
190. A person of ordinary skill in the art to
which the ‘898 and PCT applications pertain
would have an electrical engineering degree
and at least two to three years of experience in
designing computer memory circuits. (Fliesler,
Tr. 8779-80; Nusbaum, Tr. 1613).
191. It was Dr. Horowitz’s understanding
when the patent application was filed that the
various solutions to problems described in the
application could be used independently of one
another. Thus, if one did not want quite the
level of performance that Drs. Farmwald and
Horowitz envisioned, one could use only a sub-
set of the techniques described in the patent
application. (Horowitz, Tr. 8514-15).
192. Dr. Farmwald never thought of his
ideas as implementing a “narrow” bus. (Farm-
wald, Tr. 8143). Rambus originally used a 9-bit
wide bus because that corresponded to the
number of pins that could fit on the edges of
the chips that existed at the time; later
Rambus used wider buses because more pins
could be placed on the chip. (Farmwald, Tr.
8143-44). While some of the inventions of
Drs. Farmwald and Horowitz might enabie
narrower busses to work better, the inventions
473a
are not specific to a particular bus width.
(Farmwald, Tr. 8144).
193. A March 12, 1993 Mitsubishi memo-
randum begins by stating that a “need has
arisen to evaluate in detail all of the claims in
a patent being applied for by Rambus (1
patent, a total number of claims is 150).” (RX
2214A at 1). The memorandum goes on to list
guidelines for this evaluation, including “1) Do
not discuss Rambus interface. 2) Determine
whether or not any other areas contain tech-
nologies that will be important in increasing
memory speed in the future ” (RX 2214A at 1).
194. A June 10, 1993 Mitsubishi document
with the heading “RAMBUS Patent (summary
of responses)” states: “[i]n addition to the tech-
nologies of narrower bus width and communi-
cation by protocol that are described above, the
RAMBUS patent includes a variety of require-
ments such as memory system configuration,
packaging method, and device configuration,
and it can be achieved through a combination
of these factors.” (RX 406 at 4). The document
continues: “[t]he individual technologies that
appear in the RAMBUS patent will be used
independently in the future.” (RX 406 at 4).
a. Description of Access Time
Registers
195. The ‘898 application and the PCT
application describe access time registers that
store latency, that is tre amount of time be-
tween receiving a request and driving data
onto the bus in response to that request. (CX
1451 at 16, 23; CX 1454 at 16, 23; Jacob, Tr.
5481). The applications state that “|eJach slave
474a
may have one or several access-time registers,”
where “slave” can refer to a DRAM. (CX 1451
at 16; CX 1454 at 16; Jacob, Tr. 5649).
196. In common use, programmable CAS
latency in the mode register of an SDRAM is
set at initialization. (Jacob, Tr. 5648-49). The
‘898 application and PCT application state
with respect to the access time registers (and
other registers): “[m]Jost of these registers can
be modified and preferably are set as part of an
initialization sequence.” (CX 1451 at 16; CX
1454 at 16).
197. A Mitsubishi document headed “Assess-
ment of Rambus Patents (Second Half)” states
next to the numbers 95, 97 and 103: “Mod-
ifiable Access Time Register (Similar to
SDRAM latency control).” (RX 2213A at 25,
27). Claim 103 of the PCT application (and ‘898
application) refers to a “modifiable access-time
register.” (CX 1451 at 104; CX 1454 at 105).
198. In a claim-by-claim analysis of the PCT
application produced by Mitsubishi, a marginal
note identifies claim 103 of the application as
relating to latency and SDRAM. (RX 2213A at
7, 9). The analysis further indicates that
Mitsubishi determined that this claim relating
to latency in SDRAMs was particularly im-
portant, for Claim 103 was marked “A.” (RX
2213A at 7, 9). A later page of the document
explains that an “A” grade means that a
technology is “important for increasing DRAM
speed.” (RX 2213A at 27).
475a
b. Description of Block Size
199. The ‘898 application and the PCT
application describe varying the “block size,”
that is the amount of data transmitted in
response or received in response to a request.
(CX 1451 at 29-30; CX 1454 at 29-30; Jacob,
Tr. 5477-78). The applications each state that
“BlockSize [0:3] specifies the size of the data
block transfer.” (CX 1451 at 29; CX 1454
at 29). The applications each contain a table
showing the “Number of Bytes in Block”
corresponding to the value in the “BlockSize”
field. (CX 1451 at 30; CX 1454 at 30).
200. “Burst length,” as the term is used in
SDRAMs, refers to the amount of data to be
transferred per read or write transaction.
(Rhoden, Tr. 379-80; Jacob, Tr. 5396-97.)
Likewise, “block size,” encodes the amount of
data to be transferred per read or write
transaction. (Jacob, Tr. 5477). The two terms
describe the same function and are used inter-
changably. (Horowitz, Tr. 8661-62; Geilhufe,
Tr. 9643).
c. Description of Bus Clock
201. The ‘898 and PCT applications state:
“[cllock distribution problems can be further
reduced by using a bus clock and device clock
rate equal to the bus cycle data rate divided by
two, that is, the bus clock period is twice the
bus cycle period. Thus, a 500 MHz bus pre-
ferably uses a 250 MHz clock rate.” (CX 1451
at 49: CX 1454 at 50). If clock rate is half the
data rate on the bus, both edges of the clock
476a
must be used to transmit data. (Fliesler, Tr.
8801-02).
202. Figure 10 in the ‘898 and PCT appli-
cations shows two input receivers clocked by
“clock” and “clock bar” as in the Rambus tech-
nical descriptions. (CX 1451 at 147; CX 1454 at
148; Fliesler, Tr. 8799). If “clock bar” is high
when “clock” is low, and vice versa, data is
input on both the rising and falling edges of
clock. (Fliesler, Tr. 8799-800).
203. Figure 13 in the ‘898 and PCT ap-
plications shows a timing diagram with data
being input, as indicated by the arrows along
the bottom of the figure, on both the rising and
falling edges of the clock. (CX 1451 at 149; CX
1454 at 150). Howard Sussman, the JEDEC
representative for Sanyo and formerly the
JEDEC representative of NEC, testified that
Figure 13 of the PCT application shows to him
that “input being sampled on the high and low
edge of the clock” and that is “double data rate
input.” (Sussman, Tr. 1322, 1467-68).
d. Description of Variable Delay
Circuitry With a Feedback Loop
204. Figure 12 of the ‘898 and PCT ap-
plications describes variable delay circuitry
and a feedback loop. (CX 1451 at 148; CX 1454
at 149; Jacob, Tr. 5649-50).
205. When Joel Karp, then of Samsung,
reviewed Rambus’s PCT application in 1991,
Figure 12 “jumped out” at him as evidencing a
DLL. (CX 2078 at 119 (Karp Micron Dep.); CX
2114 at 276-77 (Karp Dep.)).
477a
206. In its license negotiations with Rambus
in 1994, Joel Karp felt that Samsung was
motivated to seek a non-assertion provision for
non-Rambus-compatible uses of Rambus’s in-
ventions because of the on-chip DLL shown in
Rambus’s PCT application. (CX 2078 at 107-
08, 119-20 (Karp, Micron Dep.)).
5. Review of the ‘898 or PCT
Application Should Have Raised
Concerns That Rambus Might Be
Able to Obtain Claims Over the Four
Technologies at Issue
207. A person of ordinary skill in the art or a
patent lawyer reviewing the ‘898 application
or PCT application would have realized that
Rambus might have claims broad enough to
cover programmable CAS latency, program-
able burst length, dual-edge clocking, and on-
chip DLL. (Fliesler, Tr. 8784-85, 8810-11).
208. An experienced DRAM designer review-
ing the PCT application would reach the
conclusion that there is considerable similarity
in form and function between programmable
latency, variable burst length, dual-edge clock-
ing, and on-chip DLL as described in the PCT
application and the corresponding features in
SDRAMs or DDR SDRAMs. (Geilhufe, Tr.
9556-57).
209. If an experienced DRAM designer work-
ing on designing an SDRAM incorporating pro-
grammable latency and burst length in the
early 1990’s had reviewed the PCT application,
he likely would have become concerned that
Rambus might have claims to those features
478a
and would have raised the issue with man-
agement. (Geilhufe, Tr. 9558).
210. A manager faced with this issue, in
light of the potential for substantial economic
consequences if a DRAM design infringes a
patent, would likely have gathered additional
technical analysis from specialists and, if there
remained a concern, would have taken the
issue to corporate counsel for a careful review.
(Geilhufe, Tr. 9558-59).
211. When Mitsubishi reviewed the PCT
application, it undertook an in-depth study. A
March 3, 1993 Mitsubishi memorandum re-
quests cooperation on evaluating Rambus’s
PCT patent application because they “realized
that the technology is related not only to
stand-alone semiconductor devices but also to
systems.” (RX 379A at 1).
212. A June 10, 1993 Mitsubishi document
stressed the need for expert analysis of Ram-
bus’s patent application to determine the scope
of the claims, particularly as to individual
technologies’ disclosed in the patent
application: “[t]here is a need to examine the
specifications of the patent claims to determine
whether individual technologies used
independently will infringe on the RAMBUS
patent, and for that we will have to obtain the
views and interpretations of experts.” (RX 406
at 4; see also RX 416A at 1).
213. An August 16, 1993 Mitsubishi docu-
ment again raised the issue of whether Ram-
bus could have claims on features separate
479a
from any particular bus architecture. (RX 419A
at 1).
214. A January 11, 1996 memorandum indi-
cates that Mitsubishi subsequently conducted
an “investigation of the US patents owned by
Rambus” that were granted by the end of
October 1995 and that eighteen patents met
that criteria. (RX 528A at 1).
215. Mitsubishi also maintained a chart
tracking all of Rambus’s issued U.S. patents.
For example, one version of this chart begins
with Rambus’s first issued U.S. Patent No.
5,243,703, at number one and concludes with
U.S. Patent No. 5,578,940 which issued on
November 26, 1996 at number twenty-seven. —
(RX 2216 at 2, 4). Rambus’s ‘3827 patent is
listed at number twenty-three on the chart.
(RX 2216 at 3).
216. A later version of the Mitsubishi chart
contains thirty-seven Rambus patents and in-
cludes patents that issued in early 1998. (RX
2218 at 3-6).
217. A Mitsubishi analysis of the claims of
the PCT application specifically calls out the
modifiable access time register and notes its
similarity to SDRAM latency control. (RX
2213A at 27).
218. An August 24, 1996 report on a Rambus
meeting states: “Rambus’ patents. Issued: 16,
filed: 80. For example, data is transferred at
both edges.” (RX 756A at 1).
219. As Complaint Counsel concede, Rambus
has obtained patent claims that cover pro-
Hil.
480a
grammable CAS latency, variable burst length,
dual-edge clocking, and on-chip DLL as those
features are used in SDRAMs and/or DDR
SDRAMs. (Complaint, 7 91). Rambus has as-
serted claims covering these four features
against SDRAMs and DDR SDRAMs. (Com-
plaint, J 92).
JEDEC IS A COLLABORATIVE STAN-
DARD SETTING BODY FOR THE SEMI-
CONDUCTOR INDUSTRY
A. Early History of JEDEC
220. JEDEC was founded in 1958 and
originally named the “Joint Electron Device
Engineering Council.” (CX 302 at 10; J. Kelly,
Tr. 1773-74 (““JEDEC has been active within
an EIA organization under the name JEDEC
since approximately 1958, and under other
names with slightly different functions for a
number of years prior to that, probably dating
back to the 1940s.”)).
221. The current name of JEDEC is the
“JEDEC Solid State Technology Association.”
(J. Kelly, Tr. 1750-51).
222. Between 1991 and 1996, JEDEC was an
activity within the Electronic Industries Asso-
ciation (“EIA”) Solid State Products Division,
which was itself a division of the EIA’s Com-
ponents Group. (CX 3092 at 14, 27; J. Kelly,
Tr. 2075).
223. EIA is a “broad-based association that
represents the electronics industry in the
United States, and it engages in a variety of
48la
different activities in support of that industry.”
(J. Kelly, Tr. 1750; CX 302 at 28).
224. In 1998, EIA changed its name to the
Electronic Industries Alliance and JEDEC
became a separate division of EIA. (CX 302
at 11). In 1999, JEDEC became independently
incorporated. (CX 302 at 11).
225. Both EIA and JEDEC are headquar-
tered in Arlington, Virginia. (J. Kelly, Tr.
1751).
B. The Purpose and Function of JEDEC
226. JEDEC seeks to create consensus based
standards which reflect the interests of DRAM
manufacturers and exists because of an in-
dustry need for standardization. (CX 2767 at 1;
J. Kelly, Tr. 1784; Landgraf, Tr. 1685).
C. The Organization of JEDEC
1. Member Companies
227. A company becomes a member of both
JEDEC and EIA by completing and submitting
an application and paying dues. (CX 601; J.
Kelly, Tr. 1801-02; Rhoden, Tr. 294-95). “Elig-
ible organizations can become members of
JEDEC by joining the EIA Solid State Prod-
ucts Division or by joining JEDEC directly,”
and paying annual dues. (CX 208 at 7).
228. During the time Rambus was a JEDEC
member, dues were paid to EIA. (CX 602 at
6, 7).
229. There was no contractual relationship
between JEDEC and Rambus. (J. Kelly, Tr.
2075).
482a
230. During the i990’s, JEDEC had approx-
imately two hundred fifty member companies
who sent approximately 1800 individuals to
participate in approximately fifty committees.
(J. Kelly, Tr. 1774-75).
231. In 1992, when Rambus joined JEDEC,
the membership application stated that:
“JEDEC Committee membership is limited to
companies and independent entities of com-
panies that (1) manufacture solid state prod-
ucts, or provide related services or equipment,
and (2) participate in the United States mar-
ket.” (CX 602 at 2).
232. JEDEC’s membership includes com-
panies from around the world. (Rhoden, Tr.
294 (noting companies from Korea, Germany,
Taiwan and Japan); see CX 302 at 8).
233. Membership entitles companies to
attend meetings, receive minutes, vote, and
receive copies of standards and other pub-
lications. (J. Kelly, Tr. 1805-06).
234. Companies not interested in the out-
come of a particular issue were encouraged to
abstain from voting. (Rhoden, Tr. 303-04).
235. During the early and _ mid-1990’s,
JEDEC minutes were regularly circulated to
all members. (Crisp, Tr. 3139). The minutes
were also available in the early 1990’s to non-
members, with the possible exception of a Rus-
sian company. (G. Kelley, Tr. 2622-23).
236. JEDEC manual 21-H gives committee
chairs discretion to allow guests to attend
meetings: “faJll JEDEC Committee meetings
483a
are open to members, their designated alter-
natives, and guests invited by the Committee.
Others may attend meetings only with prior
approval of the Chairman.” (RX 1211 at 10).
2. The JEDEC Council, Board of Direc-
tors and Officers
237. Today, the JEDEC Board of Directors is
the governing body of JEDEC. (J. Kelly, Tr.
1768; CX 214 at 1, 14). Prior to 1999, the
JEDEC Council was the governing body of
JEDEC. (J. Kelly, Tr. 1768).
238. Prior to 1998, the JEDEC Council could
not unilaterally set or change policies without
approval of the EIA Engineering Department
Executive Council (““EDEC”). (See J. Kelly, Tr.
2078, 2105).
239. The chairman of the board of directors
is elected by JEDEC members. (Rhoden, Tr.
286).
240. The JEDEC chairman is responsible for
“the business aspect of JEDEC, trying to make
sure that we [JEDEC] have office space, staff,
relationships with other organizations, and to
make sure that we take care of the business
aspects of the corporation itself.” (Rhoden, Tr.
286-87).
241. Desi Rhoden is the current Chairman of
the JEDEC Board of Directors. (Rhoden, Tr.
283).
242. John Kelly is the current President of
JEDEC. (J. Kelly, Tr. 1750-51).
243. John Kelly has also been the General
Counsel of EIA since 1990. (J. Kelly, Tr. 1754).
484a
244. The EIA General Counsel is “the legal
counsel for all of the operating units within
BIA, including JEDEC” (J. Kelly, Tr. 1754).
The EIA General Counsel is the person re-
sponsible for interpreting EIA rules and the
JEDEC rules, including the JEDEC patent
policy. (J. Kelly, Tr. 1939; Sussman, Tr. 1348-
49).
245. While the General Counsel may inter-
pret the policies and rules, EDEC establishes
what the policies and rules are. (J. Kelly, Tr.
2078).
246. Today, JEDEC employs a staff of ten
persons to facilitate the meetings of JEDEC
committees. (J. Kelly, Tr. 1792-93). During the
early to mid-1990’s, the size of JEDEC’s staff
was considerably smaller than the current
size. (J. Kelly, Tr. 1795).
3. The JC 42 Committee
247. JEDEC is organized into committees
and subcommittees. (Landgraf, Tr. 1687).
248. The members of each committee or
subcommittee elect a chairman. (J. Kelly, Tr.
1794).
249. The JC 42 committee is concerned with
developing standards for memory products.
The JC 42 membership consists of “[a]lmost all
of the DRAM memory companies, SRAM mem-
ory companies, logic companies, customers of
memory, as well as interconnect companies,
such as socket manufacturers,” and testing
companies. (Williams, Tr. 765-66; Rhoden, Tr.
288).
485a
250. The JC 42 Chairman is responsible for
coordinating all the activities in the JC 42
committee and subcommittees, including the
scheduling of meetings. (Rhoden, Tr. 288).
251. The JC 42 committee had several sub-
committees focusing on particular specialized
subject matters. (J. Kelly, Tr. 1769; Rhoden,
Tr. 285 (JC 42 included subcommittees devoted
to DRAM (42.3), SRAM (42.2), memory mod-
ules (42.5), flash memory and other types of
programmable devices)).
252. JEDEC’s JC 42.3 subcommittee devel-
ops standards relating to DRAM products.
(Peisl, Tr. 4381; Rhoden, Tr. 283-84).
253. In late 1991, approximately forty to fifty
companies were represented on the JC 42.3
subcommittee. (Rhoden, Tr. 340-41; JX 10 at
1-2).
254. The JC 42 committee and its related
subcommittees typically meet between four
and eight times per year. (Rhoden, Tr. 340).
255. Minutes of JC 42 committee and its
subcommittees are prepared by Ken McGhee, a
staff person. (Rhoden, Tr. 327). There is a
review process that goes on before the minutes
are made official and distributed to members.
(Rhoden, Tr. 591).
256. The minutes of JC 42 and its sub-
committees record the key decisions that are
made during the standard development proc-
ess, including motions and votes. (Rhoden, Tr.
327-28). The minutes were intended to be a
chronological statement of the events and
486a
occurrences in the meeting, although they
were not a transcript. (Rhoden, Tr. 590-91).
D. The Standard Development Process
257. The standard development process be-
gins with discussions among the participants
at a JEDEC meeting -oncerning subjects that
members may feel should be considered as
possible standards. (Rhoden, Tr. 406-07).
258. JEDEC entertains a number of pro-
posals by members when working toward a
standard for a new device. (Rhoden, Tr. 415).
259. JEDEC members decide which of these
ideas to pursue. (Rhoden, Tr. 415-416).
260. There is a first showing or first pres-
entation when proposals typically receive an
item number. (Calvin, Tr. 1025).
261. In some cases, discussions of possible
features generate a survey ballot that requests
the members to give their views concerning
different solutions. (Rhoden, Tr. 481, 516).
262. Following the conclusion of the second
or subsequent presentations, the committee
decides if it wants to create a ballot to vote on
the substance of a proposed standard. (Rhoden,
Tr. 406-07).
263. JEDEC participants often had signifi-
cant differences of opinion concerning the
development of a standard. These differences
of opinion drove heated debates concerning the
merits of the various solutions to the technical
challenges facing the JEDEC participants.
(E.g., CX 711 at 14; CX 711 at 33; CX 711 at
47; CX 680 at 1; CX 680 at 2; Rhoden, Tr. 434-
487a
35 (“if you give ten engineers a problem, you'll
probably get 12 or 14 solutions, and the same
is true inside the discussions inside the com-
mittee”)).
264. From time to time, ballots failed or were
put on hold in the JEDEC committees because
the committees did not reach a consensus. (JX
12 at 6, 12; JX 19 at 10; JX 26 at 5).
265. If it preferred, a committee could pass
items individually but place the individual
items on hold until an entire list of related
items that were needed to define a single
standard was complete, and once that group of
ballots wes complete and passed, then together
the committee could motion them to go to
Council for publication. (G. Kelley, Tr. 2554).
266. After a JEDEC committee approves a
standard, the proposed standard is sent by a
ballot to the JEDEC board of directors, which
then has to again by a consensus approve the
ballot in order for the proposal to become a
JEDEC standard. (J. Kelly, Tr. 1785; Rhoden,
Tr. 406-07).
267. JEDEC’s consensus based _ process
means that the board of directors will consider
any committee votes that were cast in
opposition to the proposed standard. (J. Kelly,
Tr. 1786).
268. JEDEC’s consensus based process often
requires years in order to adopt a new stand-
ard or change an existing standard. (Polzin,
Tr. 3977; Peisl, Tr. 4453 (“JEDEC is tra-
ditionally a very slowly moving consortium,
and there’s a reason for that, because there’s
488a
sO many companies involved, it’s basically the
whole industry that produces parts for the PC
and the laptop and the server business, so to
try to reach consensus at JEDEC, based on my
experience, have been incredibly hard and
tough. In the last decade, essentially there
were only two standards that emerged for SDR
and DDR.”)).
269. In order to create common parts that
are plug compatible during the 1990’s, JEDEC
standards became more detailed. (CX 35 at 14-
15; G. Kelley, Tr. 2390).
270. Formal standardization in the DRAM
industry benefits the entire industry. (Prince,
Tr. 9016-17).
271. JEDEC standards are very valuable to
manufacturers. (CX 707 at 1 (“JEDEC is a big
deal to them [Samsung] because it [JEDEC]
represents the big users.”); Peisl, Tr. 4383-84;
Bechtelsheim, Tr. 5790).
E. Rambus’s Involvement in JEDEC
1.Rambus’s Participation in JEDEC
272. The first Rambus employee to attend a
JEDEC mecting on behalf of the company was
William Garrett, who first attended a meeting
in early December 1991 at the invitation of
Toshiba. (CX 670 at 1). Garrett was later
replaced as the Rambus primary represen-
tative at the JC 42.3 Committee by Richard
Crisp, who then became Rambus’s represen-
tative at JEDEC. (Crisp, Tr. 2929).
273. In February 1994 Rambus renewed its
JEDEC membership for the 1994 calendar
~
489a
year and in April 1995 Rambus paid its dues to
renew its JEDEC membership for the 1995
calendar year. (CX 602 at 6-7).
274. The final JEDEC meeting attended by
Rambus was the meeting in December 1995.
(CX 2104 at 853-54 (Crisp, Micron Dep.)).
Rambus did not renew its membership for
1996. (CX 887).
2.Rambus Representatives Learn
About the EIA/JEDEC Patent
Policy
275. Jim Townsend, JC 42 Chairman and
IBM representative, made a presentation con-
cerning the patent policy and showed the
patent tracking list at most JEDEC meetings
attended by Crisp. (JX 12 at 5, 28-29; JX 13 at
4; CX 42A at 2; JX 15 at 4; JX 16 at 5; JX 17 at
3; JX 18 at 3, 15-18; JX 19 at 4; JX 20 at 4, 15-
18; JX 21 at 4, 14-18; JX 22 at 3, 12-16; JX 25
at 3, 18-26; CX 88A at 2; JX 27 at 4, 20-25).
276. At the May 1992 JEDEC meeting,
Chairman Townsend showed a copy of the
new American National Standards Institute
(“ANSI”) patent policy implementation guide
and secretary Ken McGhee spoke concerning
the EIA patent policies. (CX 34 at 3, 10-11; CX
34A at 2, 7).
277. At the September 1993 JEDEC meet-
ing, Townsend showed a draft of portions of
the revised JEP 21-I Manual. (JX 17 at 12; see
also CX 2092 at 63-64 (Crisp, Infineon Trial
Tr.)). The draft stated only that “the committee
Chairperson must have received written notice
from the patent holder” that the license would
490a
be made available on a reasonable and non-
discriminatory basis. (JX 17 at 12). The draft
did not impose an obligation to disclose intel-
lectual property and did not advise the Chair-
person to call attention to such an obligation.
(JX 17 at 12).
3. Rambus Continued to Stay Abreast
of JEDEC and SyncLink Activities
278. The minutes of JC 42.3 meetings are
publicly available. (G. Kelley, Tr. 2623).
279. Several sources provided information to
Rambus about JEDEC meetings after Rambus
withdrew from JEDEC. (Crisp, Tr. 3413).
280. In 1997, Richard Crisp, Rambus’s prin-
cipal JEDEC representative, received informa-
tion about JEDEC’s activities from a source
called “deep throat.” (Crisp, Tr. 3414; CX 929
at 1; CX 932 at 1 (Crisp June 1997 email: “My
‘deep throat’ (DT) source told me that the DDR
bandwagon is moving fast within JEDEC with
all companies participating.”)).
281. Crisp also received unsolicited infor-
mation relating to proceedings at JEDEC from
an anonymous source called “Mixmaster,” a
reporter Crisp called the “Carroll contact,” and
a source known as “Secret Squirrel.” (Crisp, Tr.
3414-17; CX 935 at 1).
282. Crisp shared JEDEC-related informa-
tion he received from Deep Throat, the Carroll
Contact, Mixmaster, and other sources with
Rambus executives and engineers. (Crisp, Tr.
3413-17; CX 935 at 1; CX 929 at 1; CX 973 at
1; CX 979 at 1; CX 1014 at 1).
49la
283. After June 1996, Rambus continued to
follow SyncLink’s activities. (Crisp, Tr. 3388-
89; Crisp, Tr. 3395-96; CX 711 at 183).
EARLY DEVELOPMENT AND ADOPTION
OF JEDEC DRAM STANDARDS
A. The Initial SDRAM Standard
1. Demand for a New Generation of
Memory
284. “Asynchronous DRAM” is a term that is
used to describe DRAMs that are driven off the
row address strobe (“RAS”) and column ad-
dress strobe (“CAS”) signals where the RAS
and CAS actually control the operation of the
DRAM rather than a clock. (Jacob, Tr. 5394).
285. Page mode and extended data out
(“EDO” DRAMs) are types of asynchronous
DRAM. (Sussman, Tr. 1469; Polzin, Tr. 4031).
In the late 1980’s page mode and EDO DRAMs
were commonly used in the industry. (Suss-
man, Tr. 1361). Page mode and EDO DRAMs
were standardized at JEDEC. (Sussman, Tr.
1362; Prince, Tr. 9020-21).
286. In order to respond to the fising
demand for performance and to ensure that
the new JEDEC standard would result in
common parts that were plug compatible, the
JC 42.3 subcommittee began to standardize
certain aspects of DRAM performance and
design relationships. (CX 35 at 14; G. Kelley,
Tr. 2388-91). Prior to that time, JC 42.3 work
had generally focused on standardizing the
location of pins, also known as pin-out dia-
grams. (G. Kelley, Tr. 2388).
492a
287. The JC 42.3 subcommittee subsequently
exceeded those boundaries and began stand-
ardizing certain technologies that are unre-
lated to interoperability. An on-chip DLL, for
example, as included in the DDR SDRAM
standard is not required for interoperability.
Rather, as Complaint Counsel’s technical ex-
pert, Professor Jacob, explained, the DLL used
in DDR SDRAMs is transparent to the DRAM
interface. (Jacob, Tr. 5617-18).
288. A new generation of memory was
needed because the industry anticipated that
microprocessor and computer speeds would
increase and the industry demanded memory
that could operate at the same speeds. (CX
2088 at 291-92 (Meyer, Infineon Trial Tr.)).
289. One option considered by the JC 42.3
subcommittee was to continue to develop a new
generation of EDO DRAMs. (CX 711 at 1).
290. Subsequently, “Burst EDO” was also
developed and standardized at JEDEC in mid-
1995. (Williams, Tr. 873, 879-80; RX 585 at 1).
291. Burst EDO failed in the marketplace in
competition with SDRAM. (Williams, Tr. 829).
As Dr. Oh of Hyundai Electronics Industries
Co., Ltd. (“Hyundai”) testified regarding Burst
EDO: “this is enhanced version of EDO, and
we wanted to convince our customers the
advantages of this part, but was not accepted
by our customers.” (CX 2108 at 236 (Oh Dep.)).
292. JEDEC also began to consider a DRAM
that had been developed by IBM called “High
Speed Toggle.” (G. Kelley, Tr. 2584-85). High
493a
speed toggle is also known as “HST.” (G.
Kelley, Tr. 2441).
293. According to the definition provided by
Complaint Counsel’s expert, HST was an
asynchronous part. Professor Jacob testified
that an asynchronous DRAM is one where
asynchronous RAS and CAS signals control the
operation of the DRAM rather than a clock.
(Jacob, Tr. 5394). Since RAS and CAS were
asynchronous in HST, it follows from Professor
Jacob’s definition that HST was asynchronous.
(Rhoden, Tr. 568; Kellogg, Tr. 5173). Indeed,
a January 1992 documer’ written by Willi
Meyer of Siemens states: “IBM presented gen-
eric high speed toggle mode in Sep ‘90 which
was asynchronous.” (CX 2431 at 1; Kellogg, Tr.
5173).
294. In HST, IBM proposed to transfer data
on both edges of the toggle signal. (Kellogg, Tr.
5173; Sussman, Tr. 1381; Rhoden, Tr. 436-37;
CX 2080 at 242 (Karp, Micron Dep.)). While
some witnesses loosely referred to this toggle
signal as a “clock,” it was not a free running
clock like the system clock in a synchronous
memory such as SDRAM or DDR SDRAM.
(Rhoden, Tr. 437; Sussman, Tr. 1471).
295. IBM and Siemens made HST presen-
tations at JEDEC during 1990 and 1991 which
were included in survey ballots. (JX 2 at 92; JX
3 at 56-57; JX 3 at 7; CX 316 at 1; CX 314).
296. At the May 9, 1991 JC 42.3 meeting, the
subcommittee passed a motion to ballot the
IBM HST presentation. (JX 5 at 12). At the
same meeting Siemens also made a HST pres-
494a
entation that was like the IBM HST except it
used a G/pin instead of a new toggle pin. (JX 5
at 12).
2.Proposal of a Fully Synchronous
DRAM
297. At the JEDEC JC 42.3 meeting in May
1991, Howard Sussman of NEC proposed a
fully synchronous DRAM to JEDEC for the
first time. (Sussman, Tr. 1364; CX 2088 at 272-
75 (Meyer, Infineon Trial Tr.)).
298. It is unclear whether Sussman proposed
during his initial proposal to use a single edge
clock to input and output data and a pro-
grammable mode register to set CAS latency
and burst length. (Sussman, Tr. 1365-67 and
1373-75). There was no documentation about
the NEC proposal attached to the May 1991
minutes. (See JX 5).
299. In 1991, Sussman held an unofficial
meeting of JEDEC members in Boxborough,
Massachusetts to discuss his synchronous
DRAM proposal. (Sussman, Tr. 1369-70; CX
20). A report about that meeting prepared by
Sussman was intended to provide “a consensus
of where we were.” (Sussman, Tr. 1370). The
description of the features of Sussman’s
synchronous DRAM proposal does not include
any mention of a mode register, programmable
CAS latency, or programmable burst length.
(CX 20 at 1). A report about the Boxborough
meeting prepared by Gordon Kelley of IBM
makes clear that Sussman was proposing a
fixed CAS latency at this time. (RX 173 at 3).
Kelley’s list of the main features of the NEC
495a
proposal makes no mention of a mode register
or programmable burst length. (See RX 173
at 3).
300. At the JC 42.3 meeting on September
18, 1991, the subcommittee voted in favor of
the IBM HST technology. There were four no
votes and a number of comments. (JX 7 at 8).
NEC and Samsung commented that the use of
a separate toggle signal can limit speed. (JX 7
at 8). The subcommittee decided to put the
ballot on hold until more resolution to the
comments could be made. (JX 7 at 9).
301. Also at the JC 42.3 meeting on Sep-
tember 18, 1991, Sussman made a second pres-
entation of NEC’s SDRAM proposal. (JX 7 at
13 and 160-62; CX 2088 at 276 (Meyer, In-
fineon Trial Tr.)).
302. A number of other companies also pre-
sented synchronous DRAM proposals at this
meeting, including Texas Instruments, Tos-
hiba, and Hewlett-Packard. (JX 7 at 13, 163-
77).
303. At the September 1991 JEDEC meet-
ing, NEC’s second showing of the synchronous
DRAM proposal does not mention a mode reg-
ister, programmable CAS latency, or program-
able burst length. (JX 7 at 160-62).
304. It was not until October 1991, at a
second unofficial meeting of JEDEC members
in Portland, Oregon, that Sussman’s presen-
tation materials indicated that latency and
burst length should be programmable. Both
programmable CAS latency and programmable
burst length are included in a list of key
496a
features of the proposed device. (JX 10 at 50;
Sussman, Tr. 1373-75). A timing diagram, a
version of which had been used by Sussman at
the August 1991 non-JEDEC meeting as well
as the September 1991 JEDEC meeting, had
the following language added to the right-hand
column when it was used at the non-JEDEC
meeting in October 1991: “Latency is program-
mable.” (Compare JX 10 at 51 with CX 20 at 3
and with JX 7 at 160).
305. Toshiba also made a presentation for a
synchronous DRAM including programmable
CAS latency (JX 10 at 67), causing Howard
Kalter of IBM to remark that “programmable
latency was the cleverest item Toshiba ever
created.” (RX 199 at 2). By this time, Toshiba
was a Rambus licensee and was working on
the design of the first RDRAM chip. (Horowitz,
Tr. 8548-49).
306. At the JEDEC JC 42.3 meeting on
December 4-5, 1991 (the first JEDEC meeting
attended by Rambus), Mark Kellogg of IBM
made a presentation comparing HST to syn-
chronous DRAMs. (JX 10 at 5 and 84; Kellogg,
Tr. 5172-73).
307. Also at the JC 42.3 meeting of Decem-
ber 4-5, 1991, Howard Sussman presented the
results of a non-JEDEC meeting that had been
held in Portland, Oregon on October 24, 1991
to discuss high bandwidth DRAM. (JX 10 at 4;
Sussman, Tr. 1373). The conclusion from that
meeting was that a fully synchronous DRAM
with all signals referenced to a single positive
clock edge would best meet system require-
ments. (JX 10 at 50).
497a
308. At the JC 42.3 meeting held on Feb-
ruary 27-28, 1992, NEC, Hitachi, Fujitsu,
Toshiba, Mitsubishi and Sun all made presen-
tations regarding synchronous DRAM devices.
(JX 12 at 39, 42, 60, 69, 76, 94, 110).
309. These companies continued to also
make presentations regarding asynchronous
DRAMs that they proposed to develop as well.
For example, at the February 1992 JC 42.3
meeting, Toshiba made two presentations
regarding “address compression” for asynchro-
nous DRAMs, Fujitsu made a presentation
regarding an asynchronous DRAM in a new
kind of packaging, and NEC made a presen-
tation regarding an asynchronous DRAM with
a “revolutionary pinout.” (JX 12 at 11).
310. No further action on HST was taken at
the February 1992 JC 42.3 meeting. High
Speed Toggle items continued to be listed,
however, on an active items list presented at
the February 1992 meeting by the Subcom-
mittee Chairman. (JX 12 at 19; JX 12 at 20).
311. At a DRAM Task Group meeting on
April 9-10, 1992, NEC, Fujitsu, Toshiba,
Samsung, Hitachi and Mitsubishi presented
proposals for a fully synchronous DRAM. (CX
34 at 30, 33-36).
312. At the April 1992 DRAM Task Group
meeting, IBM proposed a slightly modified
version of its HST technology. (CX 34 at 32;
Kellogg, Tr. 5175).
313. Following the April 1992 DRAM Task
Group meeting, the JC 42.3 *subcom-
mittee decided to pursue a fully synchronous
498a
DRAM rather than IBM’s toggle mode. (G.
Kelley, Tr. 2515). The JC 42.3 subcommittee
also continued to develop various asynchro-
nous DRAMs while it was standardizing
synchronous DRAMs.
314. By the time Rambus attended its first
JEDEC meeting in December 1991, Howard
Sussman was reporting the consensus that a
“fully synchronous DRAM with all signals
referenced to a single (positive) clock edge
would best meet system requirements.” (JX 10
at 50).
315. The only evidence of consideration of
dual-edge clocking that Complaint Counsel
presented after this time is HST which actu-
ally proposed an asynchronous DRAM with
output data on both edges of a “toggle signal.”
(See CX 2431 at 1; Kellogg, Tr. 5173).
3. Inclusion of Programmable CAS
Latency and Burst Length
316. At the JC 42.3 meeting of December 4-
5, 1991, NEC presented the results of a
separate meeting in Portland, concluding that
the latency of data to the clock and the burst
length should be programmable. (JX 10 at 50).
317. At the same meeting, Texas Instru-
ments made a revised presentation of its
SDRAM proposal that also included _pro-
grammable CAS latency and programmable
burst length. (JX 10 at 4, 56; Rhoden, Tr. 419-
20).
318. Toshiba made a second showing that
included programmable CAS latency and burst
499a
length. (JX 10 at 67; Rhoden, Tr. 424). Wrap
length and burst length are the same thing.
(Rhoden, Tr. 419-20; Williams, Tr. 812-13;
Sussman, Tr. 1374-75). Neither of the ‘first
showings” at the September 1991 meeting
included programmable CAS latency and pro-
grammable burst length. (See JX 7 at 163-77).
319. The JC 42.3 Subcommittee considered a
number of alternative methods of determining
the CAS latency and burst length, including
using a fixed burst length, using pins to set the
CAS latency and burst length, and using fuses
to set CAS latency and bu™st length. (Rhoden,
Tr. 425-34; Kellogg, Tr. 5099-102 and 5130-31).
The alternative methods considered at JEDEC
were rejected. Complaint Counsel did not pre-
sent sufficient evidence to find that they ever
made it past the “first showing” stage. (See JX
10 at 5, 64, 71; Rhoden, Tr. 425-34; Kellogg, Tr.
5099-102).
320. At the December 1991 JC 42.3 meeting,
Samsung presented a proposal! for SDRAMs
that included fixed CAS latency and burst
length. Samsung proposed using a single CAS
latency of 2 and a single burst length of 8. (JX
10 at 71; Rhoden, Tr. 425-28; Kellogg, Tr.
5099-101). The Samsung proposal also in-
cluded a fuse option to select between two
different burst options. (JX 10 at 71; Rhoden,
Tr. 427-28).
321. At the December 1991 JC 42.3 meeting,
Mitsubishi presented a proposal for an
SDRAM that would use two pins, BT and WP,
to set the burst length and burst type. (JX 10
at 74; Kellogg, Tr. 5102). In its proposal,
500a
Mitsubishi provided for two burst length
options, a burst length of 4 and 8. (JX 1 at 74;
Rhoden, Tr. 430-34). The Mitsubishi presen-
tation was designated as a “first time presen-
tation.” (JX 10 at 5).
322. At the December 1991 JC 42.3 meeting,
Texas Instruments presented a proposal using
the WCBR cycle to program the mode register
to determine burst length and CAS latency.
(JX 10 at 50, 56).
323. WCBR indicates a situation where the
write signal is low and a CAS signal is sent
before the RAS signal. While common in a test
or refresh operation, CAS before RAS differs
from a normal read or write operation where
the RAS would be sent before the CAS.
(Kellogg, Tr. 5107-09).
324. At the JC 42.3 meeting of February 27-
28, 1992, NEC, Hitachi, Fujitsu, Toshiba and
Mitsubishi all made SDRAM proposals that
included programmable CAS latency and burst
length. (JX 12 at 39, 42, 60, 69, 76, 91, 94;
Sussman, Tr. 1382-83). At the same meeting,
Sun presented comments on what features it
would like to see included in SDRAMs, in-
cluding programmable CAS latency and burst
length. (JX 12 at 110).
325. At a DRAM Task Group meeting of
April 9-10, 1992, NEC, Fujitsu, Toshiba, Sam-
sung, Hitachi, Mitsubishi and IBM presented
proposals that included programmable burst
length. (CX 34 at 30, 32-35).
326. At the next meeting of JC 42.3 on May
7, 1992, the minutes of the April DRAM Task
50la
Group’s meeting were presented to the full JC
42.3 subcommittee. (CX 34 at 4 and 30-37).
327. At the May 1992 meeting of the JC 42.3
Subcommittee, Samsung, NEC, Toshiba, Hi-
tachi and Mitsubishi all made SDRAM presen-
tations that included programmable CAS
latency and burst length. (CX 34 at 44, 63, 83,
85, 99, 108, 140).
328. At the May 1992 JC 42.3 meeting, Cray
Corporation (“Cray”) gave a presentation that
proposed the use of fuses to select between a
set of features for a single bank configuration
and a set of featurers for a dual bank con-
figuration, where the feature set included,
inter alia, the CAS latency value and burst
length value. The Cray presentation was not
identified as a first showing in the minutes (see
CX 34 at 3-12), and there is no evidence that it
ever progressed to a first showing. (See Suss-
man, Tr. 1388; Kellogg, Tr. 5103-05).
329. On June 11, 1992, four SDRAM ballots
were sent out to all members. (CX 252A at 1).
One ballot sought approval for use of a
particular implementation of a mode register
which was used to program CAS latency and
burst length, as well as other features. (CX
252A at 1, 3; Crisp, Tr. 3075-76; Rhoden, Tr.
448; Williams, Tr. 811-12).
330. Richard Crisp was present at the July
1992 JC 42.3 meeting and participated for
Rambus in the discussion and the vote on the
proposals, including the mode register pro-
posal. (JX 13 at 1, 9-10). David Mooring of
Rambus also was present. (JX 13 at 2).
502a
Rambus voted “no” to the proposals. (JX 13 at
9-10; CX 2112 at 78-79 (Mooring, Dep.)).
Rambus’s comments cited technical reasons for
voting against it. (JX 13 at. 9-11). These were
the only votes cast by Rambus for or against
any JEDEC proposals.
331. The results of the vote on the mode
register ballot were presented at the next JC
42.3 meeting on July 21, 1992. (JX 13 at 9-12;
Sussman, Tr. 1393). The initial tally showed
fourteen members in support of the proposal,
five against and seven abstentions. (JX 13 at
10). Various subcommittee members offered
comments, especially with respect to the need
for a CAS latency of 4. (JX 13 at 10-11).
Finally, it was agreed to re-ballot the mode
register proposal with an optional latency
mode of 4. (JX 13 at 11).
332. At the September 16-17, 1992 JC 42.3
meeting, Sun made an SDRAM presentation
that included programmable CAS latency and
burst length. (CX 42 at 39-40).
333. On January 21, 1993, the DRAM Task
Group made minor technical edits to the NEC
mode register that included programmable
CAS latency and burst length and had pre-
viously been balloted as “Proposed Standard
for 16M Bit x 4 Sync DRAM Mode Register”
JC 42.3-92-85 (item 376.3). The DRAM Task
Group decided that a _ re-ballot was not
necessary and added the ballot to the pass-hold
category. (CX 47 at 3).
503a
4. Presentations of Additional
Technologies
a. Low Voltage Swing Signaling
334. During 1992, JEDEC work included a
number of presentations that included low
voltage swing signaling. At the February 27,
1992 JC 42.3 meeting, NEC, Fujitsu, Mosaid
Technologies Inc. (“Mosaid”), Sun and Intel all
made proposals that included low-voltage
swing signaling. (JX 12 at 39, 76, 104, 111,
113; Crisp, Tr. 3045-46). At this same meeting,
the JC 42.3 Committee discussed GTL tech-
nology for use with SDRAM. (JX 12 at 36, 56-
58, 60, 101-02, 104, 111).
335. At the April 8, 1992 Special SDRAM
Task Group meeting, the JC 42.3 Subcom-
mittee considered SDRAM proposals that in-
cluded low voltage swing signaling. (CX 34 at
32 (IBM), 33 (NEC, Fujitsu), 35 (Samsung,
Hitachi), 36 (Mitsubishi)).
336. At the May 7, 1992 JC 42.3 meeting, the
Subcommittee considered SDRAM proposals
that included low voltage swing signaling. (CX
34 at 59 (NEC), 122-123 (Fujitsu)).
337. At the September 16-17 1992, JC 42.3
meeting, the Subcommittee considered Sun’s
15 meg SDRAM specification which included
low voltage swing signaling. (CX 42 at 31).
338. Complaint Counsel did not present
evidence sufficient to find that these low
voltage swing signaling presentations were
ever balloted or that they were incorporated
into the SDRAM standard.
504a
b. Dual Bank Design
339. During 1992 and 1993, JEDEC work
included a number of presentations that in-
cluded dual bank design. At the February 1992
JC 42.3 meeting, the Subcommittee addressed
the topic of multiple active subarrays in two
presentations (JX 12 at 34, 37) and multibank
or dual bank design in other presentations.
(See, e.g., JX 12 at 60). The Subcommittee
considered proposals for multibank, or dual
bank, design from NEC, Mitsubishi, Fujitsu,
and Sun. (JX 12 at 39, 60, 76, 110).
340. At the May 7, 1992 JC 42.3 meeting, the
Subcommittee considered SDRAM proposals
that included dual bank design. (CX 34 at 59
(NEC), 122-123 (Fujitsu)).
341. During that meeting, Kelley of IBM,
prompted by Meyer of Siemens, asked Crisp
whether Rambus might have patent claims
that related to dual bank design. (CX 2089 at
i30, 133-37 (Meyer, Infineon Trial Tr.). “The
way how Mr. Kelley formulated the question
was: Do you want to give a comment on this?”
(CX 2089 at 136 (Meyer, Infineon Trial Tr.)).
Rambus declined to comment. (CX 2089 at 136
(Meyer, Infineon Trial Tr.)).
342. At the September 16-17 1992, JC 42.3
meeting, the Subcommittee considered Sun’s
15 meg SDRAM specification which included a
dual bank design. (CX 42 at 30 (“The 4M x 4
device is organized internally as two banks.”)).
343. Complaint Counsel did not present
evidence sufficient to find that these dual bank
design presentations were ever balloted or that
505a
they were incorporated into the SDRAM
standard.
c. Auto-Precharge
344, At a number of meetings during the
course of 1992, the JC 42.3 Subcommittee
discussed using the auto-precharge technology
in the SDRAM standard. (February 1992: JX
12 at 37, 39 (NEC), 76 (Fujitsu), 94 (Toshiba),
108 (Sun); April 1992: CX 34 at 32 (IBM), 33
(NEC), 35 (Hitachi); May 1992: CX 34 at 6,
150).
345. At the September 16-17, 1992 JC 42.3
meeting, the Subcommittee considered Sun’s
15 meg SDRAM specification which included
an “autoprecharge” option. (CX 42 at 45). Auto-
precharge was incorporated as a feature in the
JEDEC SDRAM 21-C standard, issued in
November 1993. (JX 56 at 115).
346. Complaint Counsel did not present
evidence sufficient to find that these auto
precharge presentations were ever balloted or
that they were incorporated into the SDRAM
standard.
d. Source Synchronous Clocking
347. At the April 1992 JC 42.3 Special Task
Group meet
