A new line of low power, low thermal dissipation memory modules, the DDR3L memory modules from Virtium Technology not only reduce total power for systems that use multiple memory modules, but because they reduce thermal dissipation up to 10°C on the DRAM surface, they also benefit systems that must run above 85°C.

JEDEC stipulates that systems running memory beyond 85°C must double the memory self-refresh rate. Compared to other current DDR3 designs, Virtium DDR3L memory modules are able to facilitate a considerable increase in system performance by removing the double refresh rate requirement. Virtium engineering solved this issue using a combination of its screening technique for lowest total electrical current (IDD), incorporating thermal-relief copper pour methodology PCB design, reducing the chip count, and utilizing 1.35V DDR3L DRAM.

Virtium DDR3L memory modules are available in 4 Gbyte and 8 Gbyte densities in a wide range of form factors including standard height, VLP and ULP low profile ECC SODIMM, RDIMM, UDIMM and Mini DIMM configurations. The company’s internal test data shows that depending upon the components used, Virtium DDR3L modules can significantly reduce power resulting in increased performance in many embedded systems.
