DDR3 Will be Cheaper, Faster in 2009

From DailyTech: New 50nm DDR3 DIMMs from Samsung and Elpida are entering mass production this month. The chips will feature higher densities and speeds while lowering latencies, power consumption, and costs.

Elpida's new 50nm process uses 193nm argon fluoride immersion lithography combined with copper interconnect technology, providing a 25 percent speed boost over standard aluminum interconnects. A standard chip size of less than 40mm2 means that there will be more dies produced per wafer, lowering costs once the line matures and yields are maximized.

The new chips are capable of 2.5Gb/s at a standard 1.5v, but can also be used at 1.2v up to 1.6Gb/s. Initial production will be at 1Gb densities. This enables new usage models in the mobile and server application space.

Corsair's Dominator GT 2GHz CL7 DDR3 DIMMs were shown at CES, and they may enter production this month using Elpida's latest.
