Elpida Memory has announced that it completed development of a 4Gb DDR3 SDRAM, which it claims is the highest density DDR3 in the DRAM industry.
Based on an advanced 40nm process, Elpida's 4Gb DDR3 uses about 30% less power compared to two 40nm 2Gb DDR3 SDRAMs (4Gb equivalent) and enables servers, data centers and other large capacity memory systems to reduce power consumption, the company said. It can operate at not only standard DDR3 1.5V but also 1.35V to allow greater system power savings.
Elpida said its 4Gb DDR3 SDRAM will be shipped for 32GB registered DIMM (72 4Gb DDR3 SDRAMs installed in 36 double-density packages) and new standard LRDIMM for servers, 8GB ECC unbuffered DIMM (18 4Gb DDR3 SDRAM installed) for workstations, 8GB SO-DIMM (16 4Gb DDR3 SDRAM installed) for notebooks and digital consumer electronic products.
Elpida has begun sample shipments of 4Gb DDR3 SDRAM in the second quarter of calendar 2010, and expects to commence mass production in the third quarter. Its fab in Hiroshima is preparing to handle manufacturing, according to the company.
