Abstract

A method of operating a nonvolatile memory cell includes providing the nonvolatile memory cell comprising a diode which is fabricated in a first resistivity, unprogrammed state, and applying a forward bias to the diode having a magnitude greater than a minimum voltage required for programming the diode to switch the diode to a second resistivity, programmed state. The second resistivity state is lower than the first resistivity state.
