Elipda, Rambus introduce 4.8GHz XDR DRAM

Intel may have ditched Rambus memory back in the Pentium 4 days, but Rambus itself is still alive and kicking. Fresh from the adoption of its XDR DRAM memory in Sony's PlayStation 3 console, the firm has teamed up with Elpida to introduce 512Mb XDR memory chips rated for operation at an effective 4.8GHz. That's a good 50% faster than the 3.2GHz XDR chips used in the PS3.

As DigiTimes reports, each of Elpida's 512Mb 4.8GHz XDR DRAM chips is capable of shoveling data at 9.6GB/s thanks to an octal data rate technology that enables eight data transfers per clock (the chips' "actual" clock speed is just 600MHz). Rambus claims it takes six DDR2-800 memory chips to achieve the same data transfer rate.

According to DigiTimes, Elpida's new XDR chips will find their way into "high-performance applications such as high-definition TV (HDTV), game console, PC, server and workstation."
