Rambus on Friday said that Samsung Electronics would offer a 1Gb XDR DRAM memory device. Samsung's 1Gb XDR DRAM device will broaden the availability of XDR technology for gaming, computing and consumer electronics applications.

 

"Samsung's market leadership means system manufacturers can be assured of a reliable supply of our XDR DRAM. With XDR memory's world-leading bandwidth performance, designers can meet their system requirements with fewer devices and greater power efficiency," said Sharon Holt, senior vice president of licensing and marketing at Rambus.

At present, XDR memory is used inside Sony PlayStation 3 computer entertainment system, certain DLP projectors, Teradici PC-over-IP computing systems, Toshiba's Qosmio laptop PCs with SpursEngine processors inside as well as Toshiba’s HDTVs featuring SpursEngine chip. Now that Qimonda has stopped production, Elpida Memory and Samsung Electronics are the only suppliers of XDR.

Sony Computer Entertainment has so far shipped around 23 million, or slightly more, PlayStation 3 game systems, each of which features four 512Mb XDR memory chips, or 256MB of XDR memory in total. Therefore, 92 million XDR chips, the vast majority of the supplied amount, have been installed into the PS3. Other consumer electronics and computing applications consumed considerably less amount of XDR DRAM.

XDR DRAM can operate at 3.20GHz to 6.40GHz clock-speeds.
