Elpida Memory Inc. unveils a 2Gb GDDR5 graphics DRAM. The 50nm process EDW2032BABG is a high-density, high-speed, low-power consumption device using copper interconnects. The device, which is the first graphics DRAM designed by Elpida, was developed at the company's Munich Design Center in Germany.

The EDW2032BABG is configured as a 64Mb x 32, 8-bank device. It has two I/O configurationsx32 and x16that customers can use in a variety of systems. And to save mass manufacturing testing costs Elpida's proprietary test method is used, making an ultra-high speed tester unnecessary.

Applications for the device used with a GPU include game consoles and PC graphics cards and in equipment that require high-performance computing for use in such areas as science and technology, physical simulation, digital image processing and video conversion. Using 2Gb GDDR5 in these applications can double the frame buffer size of each GPU compared with 1Gb memory products.

Thus, the GPU can perform high-speed processing without exchanging large-volume image data with the main memory, enabling realistic PC graphics images. Also, the use of 2Gb GDDR5 in science & technology computing and physical simulations is expected to improve system performance because systems installed with the new graphics DRAM can handle larger amounts of data and more thread processing.

Elpida is planning to produce the device at its Hiroshima Plant to provide timely and flexible response to anticipated future growth in graphics DRAM demand.

Sample shipments are scheduled in July 2010, and mass production is expected to begin in Q3 2010.
