Elpida Memory, one of the leading suppliers of dynamic random access memory (DRAM), has announced that it had completed development of a 4Gb DDR3 SDRAM, the highest density DDR3 DRAM in the industry. The company will use 40nm manufacturing process to make the product.

Elpida’s 4Gb DDR3 chip can operate at 1600MHz with not only standard 1.5V voltage, but also 1.35V to allow greater system power savings. The chips will be available with 4-bit, 8-bit and 16-bit data width in 78-ball (x4/x8) and 96-ball (x16) packages.

Elpida plans to ship 4Gb DDR3 chiips for applications to the industry's highest density 32GB registered DIMM (72 4Gb DDR3 chips installed in 36 Double Density Packages [DDP]) and high-speed/high density new standard LR DIMM (load reduced DIMM) for servers, 8GB ECC unbuffered DIMM (18 4Gb DDR3 chips installed) for workstations, 8GB SO-DIMM (16 4Gb DDR3 SDRAM installed) for notebook PCs and digital consumer electronic products.

The number of DRAM suppliers offering a 4Gb DDR3 SDRAM product line-up is limited to Samsung Electronics and Elpida Memory at the moment. In entering this market, Elpida is expected to help steady the supply of high density memory modules for severs and notebook PCs.

Elpida plans to begin sample shipments of 4Gb DDR3 chips the second quarter of 2010 and commence mass production in the third quarter. The company's fab in Hiroshima is preparing to handle manufacturing.

While that's all well and good for servers and workstations, considering 1600 and 1866 will be the new standards next year, I still am waiting on Elpida to produce their 40nm 2Gb chips in products. That mass production commenced late last year.

This product, in reality, is likely a year beyond when the 2Gb chips reach market. So...Don't anyone hold their breath. While 4Gb for the future is a good sign, I would hope the other manufacturers opt for a higher density process for their products, like Samsung on 30nm, and Micron on something likely around 34nm.
