The intrinsic stochasticity of RRAM devices successfully provides attractive properties to implement PUF. In this paper, we present a novel multistate-based RRAM PUF to realize strong tolerance against attack. By applying multilevel states with bit shuffling to the RRAM PUF, the randomness and uniqueness were enhanced close to ideal values. In addition, the bit error rate was dramatically reduced using the temperature compensation mechanism. Moreover, our new method not only enables the generation of larger challenge-response pairs (CRPs) with less footprint but also can reconfigure CRPs.
