Memristor modeling: challenges in theories, simulations, and device variability

Abstract

This article presents a review of the current development and challenges in memristor modeling. We review the mechanisms of memristive devices based on various classifications and survey the progress of memristive models and simulations. Besides the classical theoretical models, different modeling architectures are compared, including first-principles, modular dynamics and finite element tools such as COMSOL and MATLAB. The challenges and strategies for memristors with non-ideal mechanisms, including large parameter variations, modeling algorithms and simulation roadblocks are also discussed.
