Elpida Develops 50nm DDR3 SDRAM

Elpida Memory Inc has completed development of a 50nm process DDR3 SDRAM. The DRAM product features what it said is the lowest power consumption in the industry, 2.5Gbps ultra high speed and a 1.2V low voltage operation based on the industry's smallest chip size.

Developed using 193nm (ArF) immersion lithography technology and copper interconnect technology, the 50nm process DDR3 SDRAM has a chip size of less than 40mm².

In addition, the eco-friendly SDRAM operates on not only DDR3 standard 1.5V supply voltage but even lower voltages of 1.35V and 1.2V. It contributes to the low-power operations of high-density memory systems such as servers and data centers.

The DDR3 SDRAM will initially find applications in high-end desktop PCs. The company said applications are possible elsewhere based on the current shift away from DDR2 SDRAMs in notebook PCs and server equipment.

Mass production of the 50nm DDR3 SDRAM is scheduled to begin in the first quarter of 2009.
