Patent ID: 8598561

Claim:
A nonvolatile memory device, comprising: a first conductive layer having: a first major surface; and a second major surface on a side opposite to the first major surface; a second conductive layer having: a third major surface facing the first major surface and including a plane parallel to the first major surface; a fourth major surface, the third major surface being provided between the fourth major surface and the first major surface; a side face connected with the third major surface and the fourth major surface; and a corner part provided between the third major surface and the side face, the corner part having a curvature higher than a curvature of the third major surface; a resistance change layer provided between the first conductive layer and the second conductive layer, a resistance of the resistance change layer being configured to change by at least one of an electric field applied to the resistance change layer and a current applied to the resistance change layer; and a rectifying element provided to face the second major surface of the first conductive layer, an area of the third major surface being smaller than an area of the second major surface, wherein an area of the first major surface is smaller than the area of the second major surface.
