64Kb logic RRAM chip resisting physical and side-channel attacks for encryption keys storage

Abstract

A 64Kb logic Resistive Random Access Memory (RRAM) test chip for encryption keys storage is presented for the first time. The excellent security features of resisting physical attacks and side-channel attacks are theoretically analyzed and experimentally proved. The chip is fabricated in 0.13 μm standard logic process, and can directly integrate with encryption logic circuits of information systems. © IEICE 2012.
