Toshiba has moved up the volume introduction date for Rambus Yellowstone memory technology from 2006 to 2005 as said it was sampling a 512-Mbit DRAM in a format based on the XDR interface developed by Rambus, which it claims has the fastest sustained data transfer of any memory. The DRAM has a data transfer speed of 3.2-GHz (sic) with cycle times of 40 or 50 nanoseconds and latencies of 27 or 35-ns. XDR — formerly known as Yellowstone — DRAMs are designed for broadband applications, including digital consumer electronics, network systems and graphic systems.
