The material exhibits a change in material properties, both electrical and optical, when changed from the amorphous (disordered) to the polycrystalline (regularly ordered) state. Memory is expected to play a key role in this form of computing and, in particular, phase-change memory (PCM), arguably the most advanced emerging non-volatile memory technology. Phase change memory (PCM) is an emerging memory tech-nology with many attractive features: it is non-volatile, byte-addressable, 2–4X denser than DRAM, and orders of magnitude better than NAND Flash in read latency, write latency, and write endurance. Today. Because no electrical power is required to maintain either phase of the material, so phase-change memory is non-volatile. May 5, 2012 - Phase change memory breakthrough may be on the horizon. Si la fréquence est de 50 Hz, alors les trois phases sont retardées l'une par rapport à l'autre de 1 ⁄ 150 seconde (soit 6,6 ms). PRAMs exploit the unique behaviour of chalcogenide glass.
