1. A nonvolatile memory device, comprising:
- at least one memory cell which comprises a diode and a metal oxide antifuse dielectric layer; and
a first electrode and a second electrode electrically contacting the at least one memory cell;
wherein in use, the diode acts as a read/write element of the memory cell by switching from a first resistivity state to a second resistivity state different from the first resistivity state in response to an applied bias.
