Elpida to produce 4-gigabit DRAM

ntttttttttttt

Elpida Memory Inc will begin producing 4-gigabit DRAM later this month in response to growing demand for information technology equipment accompanying a surge in data center construction.

Using 45-nanometer process technology established in the second half of last year, the company was able to increase chip capacity to 4G, double that of its previous largest-capacity chips.

The new DRAM will be compatible with the new DDR3 standard, which has a 1.5-volt supply voltage. The company’s 2G DRAM chips use the same processing technology. Capacity was increased by altering materials that store the electric charge and by re-engineering internal circuitry.

The 4G chips are expected to be used in servers and personal computers. Elpida will likely offer memory modules composed of several 4G chips. This will enable chip count per module to be reduced, thereby helping cut power consumption.
