Correction of Bit-Aliasing in Memristor-Based Physically Unclonable Functions With Timing Variability

IEEE Access, 2019
The dependence between the write time and process variation of a memristor was investigated as a candidate physically unclonable function (PUF). Such write-time-based approach requires exact timing control of the programming pulse to achieve well ...
