Abstract :
A survey of non-volatile, highly scalable memory devices which utilize dedicated resistive switching phenomena in nanoscale chalcogenide-based memory cells is presented. The classification of the memory effects, the understanding of the underlying mechanisms, and the crucial role of structural defects are outlined.
