Physical modeling and logic circuit implementation of Y2O3 based memristor

Abstract

This work is a combination of comprehensive study of memristor physical modeling using COMSOL Multiphysics software and the application view of memristor in the Cadence Virtuoso. Memristors are a novel class of passive circuit elements that exhibit a unique property of memory, making them an exciting area of research for next-generation computing and memory devices. The goal of this work is to create a memristor physical model that is reliable and effective at predicting electrical behaviour and also able to implement digital circuits that is reliable and can replace CMOS based circuits . The work begins with a detailed literature review of the memristor and it’s existing memristor physical models and switching mechanisms. After a thorough understanding of the underlying physics and proposed memristor model that takes into account various factors such as the filament formation, ion migration, and electrical conduction mechanisms in memristive devices. The model is implemented in COMSOL Multiphysics, a powerful finite-element analysis software that can accurately simulate the complex behavior of memristors.The accuracy of the proposed model is verified by comparing the simulation results with the experimental data available in the literature. The simulation results are found to be in good agreement with the experimental data, indicating the accuracy of the proposed model.
