Samsung recently announced it has successfully validated the first 40nm 1Gbit DDR2 chip and a 1GB DDR2 SODIMM module.

Today it raised the bar even further, saying it would mass produce 40nm DDR3 chips by the end of the year. There's not much info on the new upcoming 40nm DDR3 products, we just know it will be a 2Gb DDR3 part, and that it should enter mass production in late 2009.

The new 40nm process promises power savings of about 30 percent and is a major step toward a transition to DDR4.
