This work presents a highly reliable and tamper-resistant design of Physical Unclonable Function (PUF) exploiting Resistive Random Access Memory (RRAM). The RRAM PUF properties such as uniqueness and reliability are experimentally measured on 1 kb Hfû2 based RRAM arrays. Firstly, our experimental results show that selection of the split reference and offset of the split sense amplifier (S/A) significantly...
This work presents the optimized design of a physical unclonable function (PUF) primitive based on the cross-point resistive random access memory (RRAM) array. The randomness of the PUF comes from the resistance variation of RRAM cells in the array. A four-cell selection scheme is proposed to create a large number of challenge-response pairs necessary for achieving a high security level. To analyze...
