Memory technologies have seen significant advancements in recent years, driven by the increasing demands for higher performance, den- sity, and energy efficiency in computing applications. This review article presents an overview of emerging memory technologies, including Resis- tive RAM (ReRAM), Phase Change Memory (PCM), Magnetoresistive RAM (MRAM), and Ferroelectric RAM (FeRAM), analyzing their un- derlying mechanisms, potential applications, and integration challenges within current and future computing architectures. These technologies promise to bridge the gap between volatile DRAM and non-volatile flash storage, offering novel solutions that address scalability, endurance, and speed issues. We also explore the opportunities they present in the con- text of neuromorphic computing and in-memory computing paradigms. The discussion is contextualized within the framework of current research trends and industrial developments, illuminating the path forward towards next-generation memory solutions. An accompanying figure illustrates the relative positions of these technologies in terms of crucial metrics such as speed, endurance, and cost.
