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.
XDR2 DRAM is intended for use in high-end graphics cards and networking equipment.
As a fabless semiconductor company, Rambus only produces a design; it must make deals with memory manufacturers to produce XDR2 DRAM chips, and there has been a notable lack of interest in doing so.[2]
Taiwanese memory makers all but publicly shunned XDR2, and none have publicly acknowledged talks with Rambus to adopt the technology. Available for licensing today, XDR2 simply has no serious takers.
