XDR™ Memory Architecture

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, 4-byte-wide, 6.4Gbps XDR DRAM component provides 25.6GB/s of peak memory bandwidth.

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 7.2Gbps data rates providing up to 28.8GB/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.
