Samsung claims industry's smallest 2Gb DDR3 chips

Get ready for speedy 16GB DDR3 modules. Samsung says it has developed the industry's smallest 2Gb (256MB) DDR3 memory chips using 50nm process technology. The chips support data speeds of up to 1333MHz at "1.5 or 1.35 volts," and Samsung claims they allow for 40% power savings compared to their 1Gb siblings. That comparison presumably refers to DDR3 modules of the same density, since you need fewer 2Gb chips than 1Gb ones to reach, say, 4GB.

Once the 2Gb chips hit mass production later this year, you can expect to find them in 8GB desktop and server DIMMs, 4GB SO-DIMMs for laptops and small-form-factor PCs, and 16GB registered DIMMs. The latter option will require dual-die packages, though, so it will likely cost an arm and a leg (and cater only to builders of high-end database servers and the like).

Samsung expects to rely primarily on its 50nm process to make DRAM chips next year. According to numbers from IDC, though, the Korean firm may have to wait a couple of years for 50nm 2Gb memory chips to go mainstream. 2Gb chips should represent just 3% of the market next year and 33% in 2011.
