ST, Rambus sign licensing deal

STMicroelectronics has signed an agreement with intellectual property licensor Rambus Inc. that settles all outstanding litigation between the companies, and expands existing licenses. The agreement gives Rambus access to ST’s fully-depleted silicon on insulator (FDSOI) process-technology design environment.

With this, Rambus will be able to benefit from FDSOI’s reduced silicon geometries and lower power consumption at 28nm and below in its future memory and interface solutions.

On the other hand, ST has secured license terms from the Cryptography Research, Inc. (CRI) division of Rambus to make it possible for ST to deploy Differential Power Analysis (DPA) countermeasures and CryptoFirewall core security technology across a wider range of products.

“The terms allow ST to strengthen the robustness of its ICs for set-top boxes, for home gateways for multimedia services including paid-for television,” the company said.

ST has received a license to design cryptographic countermeasures into its digital consumer chips and, in return, Rambus will be able to design future memory interfaces at 28-nm and below using ST's bulk-CMOS manufacturing process.

In settling all outstanding claims, the agreement also covers ST's use of Rambus' patented memory interfaces and serial-link innovations.

“This agreement with Rambus is an exceptional win-win-win for both parties, as they can now share and use more broadly important technologies that have great value to us, the industry and our customers,” said Gian Luca Bertino, executive vice president, digital convergence group, STMicroelectronics. “While Rambus can now use our revolutionary FD-SOI process technology in its designs, ST intends to further enhance the security of our outstanding set-top box ICs and to deploy DPA countermeasures across the whole range of our relevant product portfolio.”
