Two Samsung 2-gigabit (Gb) DDR3 solutions have been validated by Intel to work with its new Core i7 (Nehalem) PC platforms, the South Korean company announced today.

The 2Gb DDR3 devices that have passed Intel?s validation program are a DDR3 SDRAM chip (x8), and a 4-gigabyte (GB) 1066Mbps DDR3 module for desktop PCs.

The newly validated DDR3 solutions are based on 50 nanometer (nm) class technology and 2Gb memory components developed last September. By utilizing 50nm-class technology, Samsung?s 2Gb DDR3 modules can consume considerably less power than conventional 1Gb DDR3 modules, up to a maximum of 40 percent less at 1333Mbps.

According to market research firm IDC, DDR3 is expected to account for 29 percent of the total DRAM market in units sold in 2009, and attain a 72 percent DRAM market share by 2011. In addition, the DDR3 segment made up of 2Gb devices is forecast to grow from 3 percent in 2009 to 33 percent in 2011.
