CrossBar ReRAM Emerges as Advanced Node PUF Security Solution

CrossBar Inc.’s Resistive RAM (ReRAM) technology is now being used as a physically unclonable function (PUF) to generate cryptographic keys in secure computing applications. 

ReRAM keys are unique to each individual semiconductor IC, leveraging the inherent random characteristics of the ReRAM process technology. This is enabling a new class of secure computing, addressing many of the deficiencies of alternative PUF implementations.

Most PUFs today are based on semiconductor SRAM. ReRAM-based PUF technology has a higher level of randomness, lower bit error rate, and the capability of handling a broad range of environmental variations without requiring fuzzy extractors or heavy ECC.

This makes CrossBar’s solution particularly attractive for foundry nodes smaller than 28nm where embedded NVM is not readily available.
