SEMICONDUCTOR MEMORY DEVICE AND METHOD OF MANUFACTURING THE SAME
摘要:
A semiconductor memory device is disclosed, which includes a first memory cell array formed on a semiconductor substrate and composed of a plurality of memory cells stacked in layers each having a characteristic change element and a vertical type memory cell transistor connected in parallel to each other, a plurality of second memory cell arrays formed on the semiconductor substrate and having the same structure as the first memory cell array, and arranged in an X direction with respect to the first memory cell array, and a plurality of third memory cell arrays formed on the semiconductor substrate and having the same structure as the first memory cell array, and arranged in a Y direction with respect to the first memory cell array, wherein a gate voltage is applied to gates of the vertical type memory cell transistors of the first to third memory cell arrays in a same layer.
