Rambus' XDR™2 DRAM is a high-performance, power-efficient memory, optimized for high-bandwidth applications such as gaming, graphics and multi-core computing. Initial devices are capable of 9.6Gbps data rates providing up to 38.4GB/s of bandwidth from a single 4-byte-wide device. The roadmap for XDR2 extends to 12.8Gbps data rates providing 51.2GB/s of bandwidth per device.
The XDR2 DRAM uses a traditional 8-bank CMOS DRAM core, with standard and micro-threaded operating modes. XDR DRAM support device densities from 512Mbit to 4Gbit with initial devices targeting 1 Gbit density. In addition to using Rambus micro-threading, XDR2 DRAM also incorporates other Rambus innovations such as Flexlink™C/A: the industry's first full-speed, scalable point-to-point command/address channel. Flexlink C/A, combined with programmable DRAM width and Enhanced Dynamic Point-to-Point (DPP), allows for highly scalable memory system capacity and access granularity, making XDR2 the ideal solution for a wide range of applications.Micro-threading is a new operating mode available in XDR2 DRAM which effectively doubles the number of individually addressable, simultaneously accessible banks. A standard 8-bank core can thus perform effectively as a 16-bank memory device, reducing column access granularity and increasing usable bandwidth to the controller.
