Abstract
A nonvolatile memory device includes via holes () formed at cross sections where first wires () cross second wires (), respectively, and current control elements () each including a current control layer (), a first electrode layer () and a second electrode layer () such that the current control layer () is sandwiched between the first electrode layer () and the second electrode layer (), in which resistance variable elements () are provided inside the via holes (), respectively, the first electrode layer () is disposed so as to cover the via hole (), the current control layer () is disposed so as to cover the first electrode layer (), the second electrode layer () is disposed on the current control layer (), a wire layer () of the second wire is disposed on the second electrode layer (), and the second wires () each includes the current control layer (), the second electrode layer () and the wire layer () of the second wire.
