Samsung Electronics Develops First GDDR4 Graphics DRAM

Samsung Electronics has developed the industry's fastest computer graphics memory and has shipped it to major graphics card manufacturers for testing. The first GDDR4 developed is a 256Mb chip that runs at 2.5Gbps.

Samsung Electronics has used DBI (Data Bus Inversion) and Multi-Preamble in the development of GDDR4 to eliminate data transmission delays. The result is a transmission speed claimed to be 56% faster than graphics products on the market today.

GDDR4 retains a design virtually identical to that of GDDR3, today's graphics DRAM of choice. This minimizes inconvenience to graphics card and chipset manufacturers in developing new products.

Samsung plans to introduce samples of 2.8Gbps GDDR4 by the end of this year with mass production to follow by the second quarter of 2006.
