Phase change memory: Operation, current challenges and future prospects

Abstract

Phase change memory has become known and most advanced resistive memory technology to meet the consumer's applications. It is a non-volatile random access memory. It plays a vital role in order to overcome the increasing demand of powerful data storage devices. In the present paper, advantages over other memories have been discussed in detail. This review focuses on the device operation of PCM. The current challenges and future prospects have also been outlined.
