TOKYO Toshiba Corp. has begun sampling a 512-megabit XDR DRAM part for the first time among Rambus XDR licensees.
XDR DRAM features an octal data rate, which transfers eight blocks of data per one clock cycle. The first generation XDR achieves a 3.2-GHz data rate per pin using a 400-MHz clock cycle, the world's fastest speed for any memory device, Toshiba claimed.
"Toshiba has been playing a leadership role in realizing XDR DRAM technology," said Shozo Saito, a Toshiba technology executive with its semiconductor unit. "In October 2002, we were first to license Rambus' most advanced technologies, and we have promoted their development ever since. Our efforts have borne fruit, as we are first in the world to sample XDR DRAM, and do so well ahead of our original schedule."
Saito said Toshiba will aim for volume production in 2005.
Along with Toshiba, Rambus has licensed XDR technology to Elpida Memory Inc. and Samsung Electronics. Elpida plans to begin sampling of its XDR part in spring 2004. Samsung has not yet disclosed its plan.
