XDR™ Memory Architecture

RDRAM®, Rambus' first mainstream memory architecture, has been implemented in hundreds of millions of consumer, computing and networking productsfrom leading electronics companies including Cisco, Dell, Hitachi, HP, Intel, Panasonic, SiS, Sony, Texas Instruments, and Toshiba.

RDRAM is no longer in high-volume production, but RDRAM components and RIMM modules are available from suppliers such as Samsung, Kingston, and Viking Components. For general information about RDRAM components and RIMM modules, see the page.

The Rambus' next-generation solution for high-performance, high-bandwidth consumer and computing applications. XDR DRAM is currently in volume production, and is available from

The XDR™2 memory architecture is the world's fastest memory system solution capable of providing twice the peak bandwidth per device when compared to a GDDR5-based system. Further, the XDR2 memory architecture delivers this performance at 30% lower power than GDDR5 at equivalent bandwidth.

Designed for scalability, power efficiency and manufacturability, the XDR2 architecture is a complete memory solution ideally suited for high-performance gaming, graphics and multi-core compute applications.

Initial systems can achieve memory bandwidths of over 500GB/s into an SoC. Each XDR DRAM can
