Rambus licenses Yellowstone and Redwood to Sony and Toshiba

Rambus signed a contract with Sony Corporation, SCEI (Sony Computer Entertainment) and Toshiba providing the latter with licenses and the right to use Yellowstone and Redwood high-speed interfaces. According to provisional data, both interfaces will be used in the Cell project ("supercomputer-on-a-chip”, developed by IBM Microelectronics, to be made using 0.10-micron and smaller process technology. Sony plans to use the Cell architecture in its PlayStation 3 game console).

There is much information about Yellowstone or Yellowstone Octal Data Rate (ODR) present for now: the new memory bus is expected to raise the throughput and performance, and also the production expenses due to lower pincount and more economical circuitry and PCB.

As for the Redwood technology, defining the high-speed parallel interface for inter-chip data transfers, Rambus claims it will provide higher-degree performance and lower latencies than current buses and will be used the Cell project as well.

Cell superchips, expected in the market in the late 2004 – early 2005, will represent the highly integrated multifunctional chips with up to 1 trillion mathematical operations per second performance (surpassing 2.5GHz Pentium 4 by about 100 times).

Returning to the today´s deal, it’s worth mention it ensures Rambus receives about $28 million within 18 months.
