The probabilistic switching of resistive random access memory (RRAM) can be utilised to implement physical unclonable functions (PUFs). By setting the operation condition at a switching probability of 50%, devices in a RRAM array are randomly settled into state ‘0’ or ‘1’ after programming. The RRAM switching probability provides a natural source of randomness that could be exploited in the PUF to generate security primitives. The feasibility and characteristics of the proposed PUF are analysed by simulation based on measured RRAM switching probability. With good scalability and stochastic mechanisms, RRAM may prove to be a promising candidate for security applications.
