Memory is one of the most important electronic components. Over the years, memory technologies have been developed to have higher capacity, faster data transfer, and lower power operations; these performance indicators are crucial to keeping up with the increasing demand for high-performance computing. However, conventional technologies such as flash, static (SRAM) and dynamic random access memories (DRAM) face scalability issues. This chapter overviews some important emerging memory technologies based on oxide perovskite materials that have the potential to replace those conventional memories in the foreseeable future. These emerging memories are fast and nonvolatile (able to store information without a continuous supply of power) and, hence, could potentially be used as both system and secondary memories in computing architecture. We discuss the basic concept, recent development, as well as their potential use beyond storage application. © 2023 Elsevier Ltd. All rights reserved.
