Elpida will begin shipping 800MHz 256Mb DDR 2 SDRAM chips in two months' time - the "industry's first" DDR 2 devices to reach 800Mbps operation - the memory maker said today.

The chips will be available in 8- and 16-bit widths ready for incorporation into DIMMs. Elpida is sampling the 8-bit parts now, and expects to offer 16-bit chip samples next month. Volume production will commence in May, it said. Both versions are fabbed at 110nm.

The devices operate at 1.85V and CAS Latency - the length of time between the chip receiving a command to read data, and the first piece of data being sent back - of 5, Elpida said.

The company is pitching the memory at high-end PCs with a frontside bus of 800MHz and up, though there's not yet any chipset that will cope with DDR 2 clocked above 667MHz.

Elpida said it had made a 1Gb 800MHz DDR 2 part last November. It provided no guidance on availability, but with 256Mb versions only coming on steam now, commercial 1Gb parts are some way off yet. ®
