JEDEC to drive DDR 2 to 800Mbps

Devising versions for notebooks and handhelds too

Memory standards organisation JEDEC has founded a team to investigate how to extend the current DDR 2 SDRAM spec. to 400MHz and a per pin data throughput of 800Mbps.

It has also approved a preliminary specification for a DDR 2-based mini-DIMM replacement for today's notebook-oriented SO-DIMM format. It is looking to expand the usage of DDR 2 to handheld devices like PDAs and cellphones.

Memory manufactures are currently sampling DDR 2 parts offering 400Mbps and 533Mbps data rates - 667Mbps DDR 2 is starting to appear too. JEDEC wants to follow these up rates quickly with 800Mbps, EBN reports. DDR 2 is expected to begin shipping in volume early next year, primarily aimed at server applications. Desktop-oriented products should appear during Q2 2004, with chips for notebooks following in the second half of the year.

By then, JEDEC should have its mini-DIMM standard in place. Market acceptance will depend on the availability of solid notebook chipsets that support DDR 2.

DDR 2 for handhelds will appear sooner than that, with a final standard being put in place by June, manufacturers anticipate. The standard will incorporate power-saving technologies that complement DDR 2's low core voltage (1.8V). ®
