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 modified to decrease the cell dimensions in both a longitudinal direction (X-direction) and a latitudinal direction (Y-direction) by wet or dry process during the line/space patterning in both those directions. Smaller PCM cell size and cross-section area 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.
