Abstract:
1. A non-volatile memory device comprising: a first wiring extending in a first direction; a second wiring extending in a second direction perpendicular to the first direction; and a non-volatile memory cell which is disposed at an intersection position of the first wiring and the second wiring so as to be interposed between the first and second wirings and is configured so that a rectifying layer and a variable resistive layer are sequentially stacked above the first wiring, wherein the rectifying layer includes a first area having a width which is substantially equal to a width of the second wiring, and a second area which is formed on the first wiring side to have a width smaller than the width of the first area and to have a thickness which is ⅓ or more of a height of the rectifying layer, at a cross section perpendicular to the second direction.
