Samsung Develops World’s Highest Density DRAM

Samsung, already pleased with itself for introducing DDR, DDR2 and DDR3 RAM, said it has created the first-ever 4-gigabit (1 GB) SDRAM chip. Throw eight of these on a laptop memory stick and you’ve got twice the RAM that is currently available. It’s also more efficient than regular DDR3 memory thanks to a 50 nanometer manufacturing process, with an estimated 20 percent power savings of 2-gigabit sticks.  Transfer speeds reach 1.6 gigabits per second. Samsung doesn’t say when these chips will be commercially available, but the International Data Corporation  estimates that “over 2 gB” DDR3 RAM will comprise 3 percent of the market this year and more than half the market by 2012.
