Rambus, a technology licensing companies specialising in high-speed memory architectures, has demonstrated its XDR memory system running at data rates up to 7.2 Gbps. The demonstration comprised memory-manufacturer Elpida’s recently announced 1 Gbit XDR DRAM device and an XIO memory controller transmitting realistic data patterns.
Elpida claims the XIO memory controller is up to 3.5 times more power efficient than a GDDR5 controller, and says the total memory system can provide up to two times more bandwidth than GDDR5 at equivalent power. In addition, the XIO memory controller demonstrated bi-modal operation with support for both XDR DRAM as well as next-generation XDR2 DRAM.
“Future graphics and multi-core processors require significantly higher memory performance under extremely challenging power and thermal constraints,” says Martin Scott, senior vice president of Research and Technology Development at Rambus. “This technology demonstration highlights the outstanding power efficiency of the XDR and XDR2 memory architectures at performance levels from 3.2 to 7.2 Gbps with scalability to well over 10 Gbps.”
The XDR memory architecture has been adopted in products including the Sony PlayStation 3, DLP projectors and, Toshiba’s Qosmio portable PCs and HDTV chip sets.
