MEMORY VENDOR Micron has produced its first working DDR4 DRAM module with implementation expected in 2013.
Although JEDEC has yet to finalise the DDR4 specification, Nanya and Micron have been forging ahead designing and now fabricating 30nm 4Gbit DDR4 chips that will be part of the two firms' DDR4 product range that will include registered and low-voltage registered DIMMs and SODIMMs. According to Micron, it is already sampling DDR4 modules and expects its customers to support quick implementation in 2013.
Brian Shirley, VP of Micron's DRAM Solutions Group said, "With the JEDEC definition for DDR4 very near finalization, we've put significant effort into ensuring that our first DDR4 product is as JEDEC-compatible as it can be at this final stage of its development. We've provided samples to key partners in the market place with confidence that the die we give them now is the same die we will take into mass production."
Micron said it expects enterprise and micro-servers will be the first to use DDR4, though it is widely expected that Intel's upcoming Haswell architecture will continue to use DDR3. With AMD also saying it will stick with Socket G34 and continue to use DDR3 for its upcoming Piledriver Opteron processors, it could be a while before DDR4 modules see widespread use in servers.
Nevertheless Micron said it expects to have JEDEC complaint DDR4 parts soon after the standard is agreed, with volume production planned for the fourth quarter of 2012. µ
