IDF Spring 2004 Japan: again about DDR2/DDR3 prospects

At IDF Spring 2004 Japan they discussed issues related to implementation of the future DDR2 memory. Actually this session resembled the one held at IDF Spring 2004 in California, so if you need the basics, please read IDF Spring 2004: FB-DIMM and Memory Implementers Forum. The nearest future of DDR2. And we´ll proceed to the new details unveiled.

The new memory roadmap is more or less known: before 2004 ends we should expect DDR2-400/533 implementation, while DDR2-667/800 solutions are to go on mass sale next year, because these days they finish DDR2-667 specs development and specify DDR2-800 interchannel compatibility. DDR3 is scheduled to 2006 and later time.

The current situation around DDR2-400/533 is that most makers have already validated their server and desktop modules and launched the mass production. At the moment only SO-DIMM DDR2-400/533 modules are to be validated. Therefore, by the moment three vendors are ready to support Grandsdale chipsets with their Unbuffered DIMMs, while server Lindenhurst is already supported by Registered DIMMs of five companies.

As you know, desktop Alderwood and Grandsdale support both DDR333/400 and DDR2-400/533. Neither vendors, nr analysts do not expect DDR2 to become wide-spread in the nearest future. DDR-2 market expansion and replacement of DDR-1 might last for about a couple of years. Most likely, DDR2-400/533 sales will be additionally boosted by mobile Alviso-based Centrino platform in H2 2004.

The most interesting speech at IDF Japan was made by Elpida that outlined its future memory roadmap generally identical to Intel´s.
