American technology firm Rambus and the European Commission have reached a deal in a dispute over the royalty rate that the US Company is currently charging for patents on memory chips used in computers.

Under the terms of the deal, Rambus will have to halt the royalty rates in charges on dynamic random access memory chips, or DRAMs, which store data temporarily. The company, on its end, has agreed that it will place no royalties for two former chip standards, and will charge a mere 1.5% for later generations of the standards that will be used.

EU's anti-trust regulator had been concerned for very long that the company had committed a "patent ambush" by taking part in a "technology standards-setting body" and not being very clear while disclosing that it held patents on "aspects of the standard which the body subsequently adopted".

"Following a long and detailed examination of the facts, the commission did not find that Rambus violated the law, nor did it impose any fine", Thomas Lavelle, Senior Vice President and General Counsel at Rambus.

Currently, Rambus charges a 3.5% royalty for using the aforementioned technology.
