Simulation Study of Memristor-Based Digital Logic Circuit using Stateful Logic

Abstract

Computer technology consists of three basic block of logic gate, which is NOT, AND, and OR gate. When apply memristor into logic gate, a new logic operation needs to be introduced, called material implication, IMPLY. This study is an attempt to investigate performance of memristor using LT SPICE model with Boilek and Prodromakis window function. We incorporate the SPICE model of memristor to simulate the IMPLY stateful logic circuit. As a result, Biolek memristor switching performance is 35ms faster than Prodromakis memristor at 1.2V while both recorded highest percentage of correct output at 4Hz with similar time taken of 1s. As a conclusion, both Biolek and Pedromakis windows function simulation and transient analysis showed the characteristics of the memristor, but the current step size remained a constraint for further performance review.
