Abstract

See full text

According to one embodiment, a nonvolatile memory device includes a memory section. The memory section includes a first insulating layer, a second insulating layer and a pair of electrodes. The second insulating layer is formed on and in contact with the first insulating layer. The second insulating layer has at least one of a composition different from a composition of the first insulating layer and a phase state different from a phase state of the first insulating layer. The pair of electrodes is capable of passing a current through a current path along a boundary portion between the first insulating layer and the second insulating layer. An electrical resistance of the current path is changed by a voltage applied between the pair of electrodes.
