Phase Change Memory offers a key advantage of NVRAM: unlike Dynamic Random-Access Memory(DRAM) which is another common type of system memory, NVRAM allows information to be retained when the system is powered off. Phase change materials store information in their amorphous and crystalline phases, which can be reversibly switched by the application of an external voltage. Phase change memory (PCM) is an emerging technology that combines the unique properties of phase change materials with the potential for novel memory devices, which can help lead to new computer architectures. Against the dream of PCM as universal memory, this paper offers guidelines for PCM applications in the widespread landscape separating the short-time memory (like DRAM, short both for latency and retention) with respect to the long-time memory (like NAND, long both for latency and retention), thus contributing to the heterogeneous memory eco-system. Fundamentals of PCM have been studied in great detail, challenges have been identified, and device structures have been proposed and demonstrated. The phase change material can ex- ist in two dierent states, amorphous and crystalline, which can be used to represent zero and one.
