Abstract
The physical unclonable function (PUF) based on resistive random-access memory (RRAM) possesses a distinctive advantage that can offer higher security and lower cost than the traditional complementarymetal– oxide– semiconductor-basedcryptographicdevices and other conventionalPUFs. The intrinsic stochasticityof 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 applyingmultilevel states with bit shuffling to the RRAM PUF, the randomness and uniquenesswere enhanced close to ideal values. In addition, the bit error ratewas 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.
