STMicroelectronics, Rambus in memory design accord; increased security results
The agreement gives Rambus access to ST’s Fully-Depleted Silicon On Insulator (FD-SOI) process-technology design environment. With this, Rambus will be able to benefit from FD-SOI’s reduced silicon geometries and lower power consumption at 28nm and below, in its future memory and interface solutions.
For its part, 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. DPA is a form of attack that involves monitoring the fluctuating electrical power consumption of a target device and then using statistical methods to derive cryptographic keys and other secrets. DPA countermeasures are used to protect secret cryptographic keys, including those used to secure transactions for banking, identity, pay television, video gaming, smartphones, government, and other applications.
CryptoFirewall cores are complete hardware-based security blocks designed by CRI to protect against a wide range of attacks and tampering techniques. The new terms allow ST to further strengthen the security of its set-top box ICs and gateways for multimedia services including PayTV.
In settling all outstanding claims, the agreement also covers ST’s use of Rambus’ patented memory interface and serial-link innovations.
