Rambus has formed business tie-ups with three Japanese firms -- Sony Computer Entertainment(SCE), Sony and Toshiba in interface technology for next-generation LSIs.
This collaboration will enable Rambus to provide its two new high-speed interfaces to the three electronics firms.
The interfaces are known by their development codenames: "Yellowstone" is a DRAM interface and "Redwood" is for processor bus applications.
Specifically, the interfaces will be used with a microprocessor (codenamed "Cell"), which is now under development, in electronic devices designed for broadband.
IBM is also involved in the development of the Cell processor, but is not a part of the tie-up. However, according to Norihiko Naono, Rambus Japan president, IBM will gain access to the interface technology through its work with such companies as Toshiba and SCE.
Yellowstone was developed in order to achieve high-speed data rates of 3.2Gbps to 6.4Gbps per pin. Toshiba signed a licensing agreement to use the interface in its DRAM products in November 2002.
As concerns Redwood, Rambus has only revealed that it is a parallel interface capable of transferring data ten times faster than the latest processor bus products. For comparison, the Pentium 4 processor bus operates at a maximum transfer rate of 4.3Gbps.
Yellowstone's special feature is that it has "FlexPhase," a phase modulator that automatically compensates for skew between signals.
