XDR DRAM (extreme data rate dynamic random-access memory) is a high-performance dynamic random-access memory interface. It is based on and succeeds RDRAM. Competing technologies include DDR2 and GDDR4. XDR was designed to be effective in small, high-bandwidth consumer systems, high-performance memory applications, and high-end GPUs.

XDR2 DRAM was a proposed type of dynamic random-access memory that was offered by Rambus. It was announced on July 7, 2005 [1] and the specification for which was released on March 26, 2008. [citation needed] Rambus has designed XDR2 as an evolution of, and the successor to, XDR DRAM.

The Rambus XDRn architectures are complete memory subsystem solutions, including PHYs and DRAMs, that achieve higher performance at lower power, while requiring the fewest number of memory devices in a wide range of applications.
