Abstract: A three-dimensional memory architecture including a top cell array of memory cells, a bottom cell array of memory cells, a plurality of word lines and bit lines are coupled to the arrays. The memory cells are phase change memory (PCM) cells is modified to form a liner confined PCM material formed in the recess of a sacrificial material. Reduced contact area between the electrode and PCM cell and decreased cell material volume leads to less current required for programming the cell. The larger distance between adjacent memory cells results in less thermal cross talk. Having a smaller PCM cell size than selector size allows less of a current density requirement in the current selector (also known as a current limiter or a current steering element) in a resistive switching memory element.
