Licensing As a company with no chip production facilities of its own, Rambus conducts business by filing patents, and then licensing technologies. For example, Nintendo licensed Rambus memory for the N64 console. However, the most famous agreement was with Intel Corporation in 1996, under which Intel became obligated to use RDRAM as the primary memory technology for all Intel platforms until 2002.

In exchange for this, Intel was given a cut of Rambus's royalties, which Intel management anticipated would be a lucrative source of high margin revenue. In reality, the RDRAM standard did not prove to be popular, and motherboard manufacturers simply bought chipsets which supported SDRAM technology from VIA Technologies rather than more expensive RDRAM chipsets from Intel. Ironically in this manner, one of the most enduring achievements of Rambus was to facilitate the rise of VIA Technologies by creating a lucrative market vacuum. A motherboard is the central or primary circuit board making up a complex electronic system, such as a modern computer. ...

As the market for RDRAM was overtaken, Rambus developed new memory interfaces for high speed activity and has continued to license these. Rambus has targeted the graphics card industry and licensed its technology to Sony for incorporation into Cell Technology as implemented with Play Station 3. It also developed PCI Express interfaces and in 2006 it licensed its XDR DRAM memory controller to Toshiba.[2] The PlayStation 3 (PS3) will be Sonys seventh generation era video game console in the PlayStation series. ...

Technology The first PC motherboards with support for RDRAM debuted in 1999. They supported PC800 RDRAM, which operated at 800 MHz and delivered 1600 MB/s of bandwidth over a 16 bit bus using a 184 pin RIMM form factor. This was significantly faster than the previous standard, PC133 SDRAM, which operated at 133 MHz and delivered 1066 MB/s of bandwidth over a 64 bit bus using a 168 pin DIMM form factor. Bandwidth is the difference between the upper and lower cutoff frequencies of, for example, a filter, a communication channel, or a signal spectrum, and is typically measured in hertz. ...

Some downsides of RDRAM technology, however, included significantly increased latency, heat output, manufacturing complexity, and cost. PC800 RDRAM operated with a latency of 45ns, compared to only 7.5ns for PC133 SDRAM. RDRAM memory chips also put out significantly more heat than SDRAM chips, necessitating heatsinks on all RIMM devices. RDRAM also includes a memory controller on each memory chip, significantly increasing manufacturing complexity compared to SDRAM, which used a single memory controller located on the northbridge chipset. RDRAM was also two to three times the price of PC133 SDRAM due to a combination of high manufacturing costs and high license fees. DDR SDRAM, introduced in 2000, operated at an effective clockspeed of 266 MHz and delivered 2100 MB/s over a 64-bit bus using a 184 pin DIMM form factor. RAM Latency is the amount of wait time that a computer experiences when trying to access data in its RAM. RAM latency is measured in front side bus clock cycles. ...

With the introduction of the i840 chipset, Intel added support for dual-channel PC800 RDRAM, doubling bandwidth to 3200 MB/s by increasing the bus width to 32 bit. This was followed in 2002 by the i850E chipset, which introduced PC1066 RDRAM, increasing total dual-channel bandwidth to 4200 MB/s. Also in 2002, Intel released the E7205 Granitebay chipset, which introduced dual-channel DDR support for a total bandwidth of 4200 MB/s, but at a much lower latency than competing RDRAM. In 2003, Intel released the i875P chipset, and along with it dual-channel DDR400. With a total bandwidth of 6400 MB/s, it marked the end of RDRAM as a technology with competitive performance.

Rambus survived the obsolesence of RDRAM and moved to support DDR and DDR2 in the area of video card technology and in particular, PCI Express. Rambus developed and licensed its XDR RAM technology. XDR DRAM is a high performance RAM Interface like SDR-SDRAM and DDR-SDRAM. The XDR solution was engineered to be effective in small high-bandwidth consumer systems as well as in high-performance main memory applications. ...
Lawsuits In the early 1990s, Rambus was invited to join the Joint Electron Device Engineering Council. Rambus had been trying to interest memory manufacturers in licensing their proprietary memory interface, and numerous companies had signed non-disclosure agreements to view Rambus’ technical data. During the later Infineon v. Rambus trial, Infineon memos from a meeting with representatives of other manufacturers surfaced, including the line “[O]ne day all computers will be built this way, but hopefully without the royalties going to Rambus”, and continuing with a strategy discussion for reducing or eliminating royalties to be paid to Rambus. As Rambus continued its participation in JEDEC, it became apparent that they were not prepared to agree to JEDEC’s patent policy requiring owners of patents included in a standard to agree to license that technology under terms that are ‘reasonable and non-discriminatory’,[3] and Rambus withdrew from the organization in 1995. Memos from Rambus at that time showed they were tailoring new patent applications to cover features of SDRAM being discussed, which were public knowledge (JEDEC meetings were not considered secret) and perfectly legal for patent owners who have patented underlying innovations, but were seen as evidence of bad faith by the jury in the first Infineon v. Rambus trial. The Federal Court of Appeals rejected this theory of bad faith in its decision overturning the fraud conviction Infineon achieved in the first trial (see below). JEDEC stands for Joint Electron Device Engineering Council and is the semiconductor engineering standardization body of the Electronic Industries Alliance (EIA), a trade association that represents all areas of the electronics industry. ...

In 2000, Rambus began filing lawsuits against the largest memory manufacturers, claiming that they owned SDRAM and DDR technology. Seven manufacturers, including Samsung, quickly settled with Rambus and agreed to pay royalties on SDRAM and DDR memory. When Rambus sued Infineon Technologies, however, Micron and Hynix joined forces with Infineon to fight the lawsuit, countersuing with claims of fraud. This trio of memory manufacturers became known as “The Three Amigos”. In May 2001, Rambus was found guilty of fraud for having claimed that they owned SDRAM and DDR technology, and all infringement claims against memory manufacturers were dismissed. In January 2003, the Federal Court of Appeals overturned the fraud verdict of the jury trial in Virginia under Judge Payne, issued a new claims construction, and remanded the case back to Virginia for re-trial on infringement. In October 2003, the US Supreme Court refused to hear the case. Thus, the case returned to Virginia per the Federal Court of Appeals ruling.

In January 2005, Rambus filed four more lawsuits against memory chip makers Hynix Semiconductor, Nanya Technology, Inotera Memories and Infineon Technology claiming that DDR 2, GDDR 2 and GDDR 3 chips contain Rambus technology. In March 2005, Rambus had its claim for patent infringements against Infineon dismissed. Rambus was accused of shredding key documents prior to court hearings, the judge agreed and dismissed Rambus’s case against Infineon. This sent Rambus to the settlement table with Infineon. Infineon has agreed to pay Rambus quarterly license fees of $5.9m and in return, both companies ceased all litigation against each other. The agreement runs from November 2005 to November 2007. After this date, if Rambus has enough other agreements in place, Infineon may make extra payments up to $100m. Currently, cases involving Micron and Hynix remain in court. In June 2005, Rambus also sued one of its strongest proponents, Samsung, the world's largest memory manufacturer, and terminated Samsung's license. Samsung had promoted Rambus's RDRAM and currently remains a licensee of Rambus's XDR memory. XDR DRAM is a high performance RAM Interface like SDR-SDRAM and DDR-SDRAM. The XDR solution was engineered to be effective in small high-bandwidth consumer systems, high-performance main memory applications, and flagship GPUs. ...
In May 2002, the United Stated Federal Trade Commission filed charges against Rambus for antitrust violations. Specifically, the FTC complaint asserted that through the use of patent continuations and divisionals, Rambus pursued a strategy of expanding the scope of its patent claims to encompass the emerging SDRAM standard. The FTC’s antitrust allegations against Rambus went to trial in the summer of 2003 after the organisation formally accused Rambus of anti-competitive behaviour the previous June, itself the result of an investigation launched in May 2002 at the behest of the memory manufacturers. The FTC’s chief administrative-law judge, Stephen J. McGuire, dismissed the antitrust claims against Rambus in 2004, saying that the memory industry had no reasonable alternatives to Rambus technology and was aware of the potential scope of Rambus patent rights, according to the company. Soon after, FTC investigators filed a brief to appeal against that ruling. FTC headquarters, Washington, D.C.

In 2004, Infineon plead guilty to price-fixing in an attempt to bury Rambus and force RDRAM out of the market. They later paid a fine of $160 million dollars. Hynix and Samsung followed suit in 2005 and paid $185 million and $300 million respectively. Elpida is the most recent company to plead guilty and paid a fine of $85 million, the lowest of all memory manufacturers. It is widely believed that the evidence collected during the FTC’s investigation of Rambus led directly to the guilty pleas. On August 2, 2006, the Federal Trade Commission overturned McGuire’s ruling, stating that Rambus illegally monopolized the memory industry under section 2 of the Sherman Antitrust Act, and also practiced deception that violated section 5 of the Federal Trade Commission Act.[4] is the 214th day of the year (215th in leap years) in the Gregorian calendar. ...

February 5, 2007, U.S. Federal Trade Commission issued a ruling that limits maximum royalties that Rambus may demand from manufacturers of dynamic random access memory (DRAM), which was set to 0.5% for DDR SDRAM for 3 years from the date the Commission’s Order is issued and then going to 0; while SDRAM's maximum royalty was set to 0.25%. The Commission claimed that halving the DDR SDRAM rate for SDRAM would reflect the fact that while DDR SDRAM utilizes four of the relevant Rambus technologies, SDRAM uses only two. In addition to collecting fees for DRAM chips, Rambus will also be able to receive 0.5% and 1.0% royalties for SDRAM and DDR SDRAM memory controllers or other non-memory chip components respectively. However, the ruling did not prohibit Rambus from collecting royalties on products based on (G)DDR2 SDRAM and other JEDEC post-DDR memory standards.
