Micron Technology has begun sampling its first DDR4 DRAM module, with plans to begin volume product in Q4 2012. Codeveloped by Nanya and based on Micron's 30-nm technology, the 4-Gb DDR4 x8 part is the first piece of a portfolio that eventually will include RDIMMs, LRDIMMs, 3DS, SODIMMs, and UDIMMs (standard and ECC). Components in x8, x16, and x32 also will be available, featuring initial speeds up to 2400 megatransfers per second (MT/s) and then increasing to the JEDEC-defined 3200 MT/s.
"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," said Brian Shirley, vice president for Micron's DRAM Solutions Group. "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."
The company expects the enterprise micro-server, ultrathin, and tablet markets to adopt the technology. For more information, visit www.micron.com.
