Litigation between Rambus and NVIDIA are drawn from the summer of 2008 : the first company accused the second in the illegal use of its development. In the initial version the suit featured 17 patents Rambus, relating to the use of memory type DDR, DDR2, DDR3, LPDDR, GDDR, GDDR2, GDDR3, GDDR4 and partially GDDR5. Last summer, the conflicting parties signed a license agreement , under which NVIDIA pledged to pay 1% of the cost of each product with the support of SDR memory, and 2% of cost of each product with support for all other memory types .
Duration of the agreement is five years, simultaneously Rambus declared the withdrawal of all claims to NVIDIA.
In January this year, Rambus company lost in litigation with Micron and Hynix, the amount in dispute is $ 4 billion. Moreover, some of the most popular of patents that Rambus blackmailed market participants, was designed to profile the American authorities as invalid. This has forced Rambus to review the license agreement with NVIDIA, which, however, were not disclosed. It is assumed that now NVIDIA will pay Rambus for the use of GDDR5 memory type , and production of graphics processors that support this standard at the level of the memory controller.
AMD and NVIDIA did not express any interest in using XDR memory type , which Rambus has been trying to market. Related Products :
