Rambus has announced that Qimonda has started shipping XDR DRAM in volume for the PLAYSTATION 3 (PS3) computer entertainment system.
Qimonda started to ship first samples of the 512Mb XDR DRAM in January 2008. The XDR memory solution extends the Qimonda specialty RAM portfolio to better serve high-performance and high-bandwidth applications for the fast growing global computing and consumer electronics markets.
The XDR memory architecture is said to be proven in high-volume, cost-competitive applications. Qimonda’s XDR DRAM, operating at 3.2Gbps, provides 6.4GB/s of peak memory bandwidth with a single, 2-byte wide device. With a roadmap extending to 6.4Gbps, providing 12.8GB/s of bandwidth per device, XDR DRAM provides an order of magnitude higher performance than today's standard memories. With XDR DRAM, designers can achieve unprecedented performance with the fewest devices.
Backed by comprehensive engineering support services that range from chip design to system integration, the award-winning XDR memory architecture features key enabling technologies built on patented Rambus innovations that include low-voltage, low-power Differential Rambus Signaling Level (DRSL); Octal Data Rate (ODR) technology that transfers eight bits of data each clock cycle; FlexPhase circuit technology for precise on-chip alignment of data with clock; and Dynamic-Point-to-Point (DPP) for both enhanced signal integrity and scalability.
