Abstract
The memristor is the fourth fundamental passive circuit element, whereby it can remember the resistance based on the last applied voltage. Hence, the name 'memory resistor'. Three memristor window functions introduced prior to this paper were taken into discussion where the memristor is inserted into the memristor-based RO-PUF. This was done in order to investigate the effect of having different memristor window functions on the RO-PUF performance in terms of uniqueness, uniformity, and bit-aliasing. While the RO-PUF produces satisfactory results individually, the effect of using different memristor window functions on the RO-PUF performance is not significant. There was little effect because the memristor linearity becomes more prominent with increasing frequency. With that, the memristor acted like a resistor at the high operating frequency of the RO-PUF. Nevertheless, the randomized parameter of initial resistance provided the RO-PUF improved performance. Thus, the RO-PUF performed as expected and is stable regardless of the memristor window function used. � 2016 IEEE.
