Abstract:
1. A nonvolatile memory device comprising: a first wire extending in a first direction; a second wire formed at height different from height of the first wire and extending in a second direction; and a nonvolatile memory cell arranged to be held between the first wire and the second wire in a position where the first wire and the second wire cross, wherein the nonvolatile memory cell includes a nonvolatile storage layer and a current limiting resistance layer connected in series to the nonvolatile storage layer and having resistance of 1 kilo-ohm to 1 mega-ohm, the nonvolatile memory cell has a structure in which the nonvolatile storage layer is held between a pair of conductive layers, and one of the pair of conductive layers or both the pair of conductive layers function as the current limiting resistance layer.
