Survey on memrister models

While hardware in a computer have developed greatly, users still has faced problems with its speed, and memory in terms of its performance. The recent developments in memristors made it possible to reduce the problems, as memristive models have been be designed to suit the requirements of time. However, different characteristics are expected from memristors depending upon its applications. The paper aims to compare three major models of memristors focusing on their advantages and limitations. It identifies the most suitable model of memristor that satisfies the memristive device conditions. Out of the three models, Voltage threshold adaptive memristor model (VTEAM) fits into the requirements and it has sufficient accuracy and computational efficiency.
