Samsung Develops 1.25Volt Green DDR3 Modules


Samsung has developed double data rate-3 (DDR3) registered dual inline memory modules (RDIMMs) designed for use in low-power enterprise server systems at a 1.25 voltage.

Utilizing four gigabit (Gb) DDR3 components based on 30 nanometer (nm) class process technology, Samsung's new DDR3 modules deliver greener memory solutions for servers than conventional 1.5 volts alternatives or the previous 1.35V version, while providing higher performance.

In case of a 1.25V 16GB RDIMM, the module consumes only 3.7 watts (W) per hour, while operating at a bandwidth of up to 1.333Mbps. This is an approximate 15 percent power savings compared to a 1.35V 16GB RDIMM using 30nm-class 4Gb DDR3 chips and an approximate 60 percent savings compared to a 1.35V 16GB RDIMM using 40nm-class 2Gb DDR3 chips.

Samsung plans to begin mass producing the modules in densities of four, eight and 16 gigabytes (GBs), after they are qualified with OEMs. Starting next year, the 1.25V RDIMMs are expected to elicit a high degree of interest in data centers and enterprise server systems, where there is the most concern for reducing energy costs and improving efficiency.
