Abstract

Phase-change memory (PCM), recently developed as the storage-class memory in a computer system, is a new non-volatile memory technology. In addition, the applications of PCM in a non-von Neumann computing, such as neuromorphic computing and in-memory computing, are being investigated. Although PCM-based devices have been extensively studied, several concerns regarding the electrical, thermal, and structural dynamics of phase-change devices remain. In this article, aiming at PCM devices, a comprehensive review of PCM materials is provided, including the primary PCM device mechanics that underpin read and write operations, physics-based modeling initiatives and experimental characterization of the many features examined in nanoscale PCM devices. Finally, this review will propose a prognosis on a few unsolved challenges and highlight research areas of further investigation.

相变记忆材料的微观结构表征、相变和器件应用。

相变存储器（PCM）是近年来发展起来的一种新型非易失性存储器技术，是计算机系统中的存储类存储器。此外，PCM在非冯-诺依曼计算中的应用，如神经形态计算和内存计算，也在研究中。尽管基于PCM的器件已经被广泛研究，但关于相变器件的电学、热学和结构动力学的几个问题仍然存在。在这篇文章中，针对PCM器件，对PCM材料进行了全面的综述，包括支撑读写操作的主要PCM器件力学、基于物理的建模举措以及在纳米级PCM器件中检测的许多特征的实验表征。最后，这篇综述将对一些尚未解决的挑战提出预测，并强调需要进一步研究的研究领域。
