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.
