A memory cell device of the type that includes a memory material switchable between electrical property states by application of energy, situated between first and second (“bottom”and“top”) electrodes has a top electrode including a larger body portion and a stem portion. The memory material is disposed as a layer over a bottom electrode layer, and a base of the stem portion of the top electrode is in electrical contact with a small area of the surface of the memory material. Methods for making the memory cell are described.
