The company added that it is now involved in all areas of the DRAM market such as commodity DRAMs, GDDR
for the graphics market, high-speed XDR DRAM and Mobile RAM for mobile equipment.
In August Elpida announced plans to enter the graphics DRAM business based on its acquisition of GDDR
design assets from the German company Qimonda AG.
Because of its high-speed data transfer capability, GDDR
is well-suited to graphics processing, which makes it a popular engineering solution among makers of advanced game consoles.
As the speed of DDR and GDDR
SDRAM devices increases, and the design margins become smaller, the performance of the probing system becomes ever more critical.
The accused products include NVIDIA products that incorporate DDR, DDR2, DDR3, LPDDR, GDDR
2, and GDDR
3 memory controllers, including graphics processors, and media and communications processors.
The lawsuit alleges that a number of NVIDIA products with memory controllers for SDR, DDR, DDR2, DDR3, GDDR
, and GDDR
3 SDRAM infringe 17 Rambus patents.
Being first to market with GDDR
in our next-generation architecture, AMD is able to deliver incredible performance using more cost-effective GPUs," said Rick Bergman, Senior Vice President and General Manager, Graphics Product Group, AMD.
