SAMSUNG Electronics recently secured the technology to produce high-density, low-power DDR2 memory. DDR2 DRAM is a 1.55V product and saves 30% more energy compared with the old 1.8V product. In addition, SAMSUNG Electronics developed the technology for low-power (1.5V) DD3 memory and super-low-power (1.35V) DD3 memory and plans to put them into production from in 2010. These products offer the greatest energy efficiency of all high-density memory products currently in use on servers. With server capacity expanding sharply, and electricity use in data centers rapidly increasing, server manufacturers are demanding components with high energy-efficiency. When low-power memory is applied to data centers that operate 24/ 7, considerable power can be saved, lowering costs while reducing global warming.
