Samsung begins mass production of Worlds First low-power 40nm-class 4Gigabit DDR3


Samsung has begun mass producing the industry’s first low-power (green) four gigabit (Gb) DDR3 devices using 40 nanometer (nm) class process technology. The high-density memory is expected to bring significant power savings to data centers, server systems and high-end notebooks. Samsung’s 40nm-class Green DDR3 is optimized to enhance energy-efficiency ratings for servers seeking to comply with or exceed new Energy Star power consumption specifications. Production of the 4Gb DDR3 raises the amount of memory for use in servers to 32Gigabytes (GB) per module, which is twice the maximum density achieved with modules based on 2Gb components.


The new 40nm-class 4Gb DDR3-based module consumes a mere 36W, which represents about 83 percent savings over the 60nm-class 1Gb DDR2 module. With growing concern about energy costs in data centers, these memory power savings translate into an overall reduction in server power of 10 percent per system. By applying Samsung’s 40nm 4Gb DDR3-based modules to existing server systems, DRAM density can raised at least two-fold and system life-time can be extended sharply to prolong server life span in reducing new system investment.
