Patent ID: 8563961

Claim:
A semiconductor storage device comprising: a substrate on which semiconductor elements are formed; a first selection line which is disposed above the substrate; a first diode layer which is disposed above the first selection line and made by stacking a p-type impurity containing semiconductor and an n-type impurity containing semiconductor; a first stacked body which comprises N+1 (N≧1) number of the first inter-gate insulator layers and N number of the first semiconductor layers alternately stacked in the height direction of the substrate and which is disposed above the first diode layer; a second selection line which extends in a direction that intersects the first selection line and which is disposed above the stacked body, a first gate insulating layer which is disposed along the side surfaces of the N+1 number of the first inter-gate insulating layers and the side surfaces of the N number of the first semiconductor layers; a first channel layer which is disposed along the side surfaces of the first gate insulating layer; and a first variable resistance material layer which is disposed on the side surface of the first channel layer and which contains a variable resistance material whose resistivity is varied by electric current, wherein the first channel layer, the first variable resistance material layer, and the first diode layer are disposed in a region where the first selection line and the second selection line intersect each other.
