Variable resistance nonvolatile memory element and method of manufacturing the same
A variable resistance nonvolatile memory element includes: first and second electrode layers; a first variable resistance layer between the first and second electrode layers; and a second variable resistance layer between the second electrode layer and the first variable resistance layer and having a higher resistance value than the first variable resistance layer. When viewed in a direction perpendicular to the major surface of the second variable resistance layer, an outline of the second variable resistance layer is located inwardly of the outline of any one of the second electrode layer and the first variable resistance layer, and an outline of a face of the second variable resistance layer, the face being in contact with the first variable resistance layer is located inwardly of an outline of a face of the first variable resistance layer, the face being in contact with the second variable resistance layer..
