摘要: According to one embodiment, a nonvolatile memory device includes a memory cell. The memory cell includes a stacked film structure. The stacked film structure is capable of maintaining a first state or a second state. The first state includes a lower electrode film, a first memory element film provided on the lower electrode film and containing a first oxide and an upper electrode film provided on the first memory element film. The second state includes the lower electrode film, the first memory element film provided on the lower electrode film, a second memory element film provided on the first memory element film and containing a second oxide and the upper electrode film provided on the second memory element film.
