October 16, 2007 // 1:50 pm - The Rambus XDR™ memory architecture is a total memory system solution that achieves an order of magnitude higher performance than today's standard memories while utilizing the fewest ICs. Perfect for compute and consumer electronics applications, a single, 2-byte wide, 4.0 GHz XDR DRAM component provides 8.0 GB/s of peak memory bandwidth.

Video can be seen here. Key components enabling the breakthrough performance of the XDR memory architecture are:

XDR DRAM is a high-speed memory IC that turbo-charges standard CMOS DRAM cores with a high-speed interface capable of 4.0 GHz data rates providing up to 8 GB/s of bandwidth with a single device.

XIO controller IO cell provides the same high-speed signaling capability found on the DRAM, but adds additional enhancements like FlexPhase™ technology that eliminates the need for trace length matching.

XMC memory controller is a fully synthesizable logical memory controller that is optimized to take advantage of innovations like Dynamic Point-to-Point which provides for capacity expansion while delivering the signal integrity benefits of point-to-point signaling.

XCG clock generator provides the system clocks with four programmable outputs and is guaranteed to meet the clocking requirements for the XIO and XDR DRAM devices.
