Technology licensing company Rambus Inc. announced that it has signed a patent license agreement with Nvidia relating to memory controllers.

 

According to the agreement, Rambus grants Nvidia a patent license for certain memory controllers at a 1% royalty rate for SDR memory controllers and a 2% royalty rate for other memory controllers, which includes DDR, DDR2, DDR3, LPDDR, LPDDR2, GDDR2, GDDR3, GDDR4, as well as bits of GDDR5 memory controllers. Nvidia hasn’t granted any licenses to Rambus.

 

The two companies' signed patent license agreement kicked in on 12 August 2010. Neither Nvidia nor Rambus has signed any releases of liability or discharged any outstanding litigation between them.

 

According to Reuters, this agreement follows the International Trade Commission’s (ITC) ruling last month that Nvidia and others had infringed upon Rambus’ chip patents. Nvidia spokesperson Hector Marinez stated that the agreement ensures that the ITC will not impose an import bar on Nvidia’s graphics processing units (GPUs).
