Claim Text:
1. A semiconductor storage device comprising: a plurality of stacked structures in which a plurality of first insulator film layers and a plurality of first gate semiconductor layers are alternately stacked above a semiconductor substrate, the stacked structures extending in a Y direction parallel to a main surface of the semiconductor substrate and being arranged at intervals in an X direction parallel to the main surface and orthogonal to the Y direction; a plurality of first gate insulator film layers provided on side surfaces in the X direction of the plurality of stacked structures; a plurality of first channel layers formed at intervals in the Y direction on the side surfaces in the X direction of the plurality of first gate insulator film layers; and a plurality of resistance-change material layers formed from a material of which the resistivity changes with a current flowing therein and disposed at intervals in the Y direction, each resistance-change material layer being between two adjacent stacked structures of the plurality of stacked structures and being electrically connected in the X direction to two adjacent channel layers of the plurality of first channel layers, thereby providing a plurality of current paths in the X direction between the two adjacent channel layers through the resistance-change material layer, each first channel layer at one side of each resistance-change material layer is coupled to be supplied with voltage independently of the other first gate semiconductor layers at the one side of the resistance-change material layer and independently of the first gate semiconductor layers adjacent to the first channel layer at an opposite side of the resistance-change material layer.
