Unconventional Logic on Memristor-Based Oscillatory Medium

Abstract

Unconventional computing systems, inspired by nature’s mechanisms, provide new ways to efficiently perform several rather complex computations. Instead of the commonly used digital computing systems, a well-known unconventional approach is the utilisation of oscillating networks to execute computations. The rich dynamics of such networks can be exploited in nanoelectronic-scale by novel devices, like memristors that incorporate inherent memory features and computing capabilities. In this work, the threshold switching mechanism of low-voltage forming-free CBRAM devices is used to develop memristor-based oscillators, which are able to function as a medium for oscillation-based computations. Given the local diffusive coupling of the proposed memristor-based oscillators, the medium is capable of performing Boolean computations through oscillation interactions.
