The Rambus XDR DRAM device is a high-performance memory device
capable of 3.2 and 4.0 GHz data rates with a roadmap supporting
4.8, 6.4, and 8.0 GHz in the future. Geared toward high bandwidth
and cost-sensitive systems like graphics processing, consumer
electronics, networking, and servers, the XDR DRAM device is a key
component of the Rambus XDR memory solution. It uses an 8-bank DRAM
core implemented in standard CMOS DRAM process technology and is
currently in production with bit densities of 256Mb and 512Mb.
Unlike other DRAM devices, the x16 XDR DRAM device implements
programmable width and supports data busses that are 8, 4, and in
some cases 2 bits wide. With this and many other architectural
enhancements, the XDR DRAM device boasts much higher efficiency and
throughput when compared with other memoriy technologies. The XDR
memory solution gives bandwidth-hungry products the performance
they need to succeed in today's demanding markets.
