XDR DRAM

Rambus XDR™ DRAM is a high-performance memory capable of 4.0 GHz data rates which can provide up to 8 GB/s bandwidth with a single 2-byte-wide device. The roadmap for XDR DRAM extends to 8 GHz data rates which would provide 16 GB/s of bandwidth per device. Designed for both high-bandwidth and cost-sensitive systems like graphics, compute and consumer electronics applications, XDR DRAM is a key component of the Rambus XDR memory architecture.

The XDR DRAM device uses an 8-bank DRAM core implemented in standard CMOS DRAM process technology and is currently in production at 512Mb density. 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 memory technologies, thus making XDR memory the ideal solution for today’s bandwidth intensive compute and consumer electronics applications.
