R&D: Phase-Change Memory for In-Memory Computing

Chemical Reviews has published an article written by Ghazi Sarwat Syed, Manuel Le Gallo, and Abu Sebastian, IBM Research−Europe, Säumerstrasse 4, 8803 Rüschlikon, Switzerland.

Abstract: “In-memory computing (IMC) is an emerging computational approach that addresses the processor-memory divide in modern computing systems. The core concept is to leverage the physics of memory devices and their array-level organization to perform computations directly within the memory array. Phase-change memory (PCM) is a leading memory technology being explored for IMC. In this perspective, we review the current state of phase-change materials, PCM device physics, and the design and fabrication of PCM-based IMC chips. We also provide an overview of the application landscape and offer insights into future developments.“
