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.
