Classification: CPC G  H | IPC G  H

Claim 18:
19. The nonvolatile memory device of claim 18, wherein
the dielectric film has a plurality of movable oxygen vacancies distributed therein, and
the dielectric film is configured such that, in response to the positive program voltage being applied to the selected memory cell through the bit line, the oxygen vacancies move toward an interface between the semiconductor layer of the selected memory cell string and the dielectric film of the selected memory cell string in a partial region of the dielectric film of the selected memory cell string corresponding to the selected memory cell, a density of the oxygen vacancies increases at the interface between the semiconductor layer of the selected memory cell string and the dielectric film of the selected memory cell string, and a resistance of the partial region of the dielectric film of the selected memory cell string is reduced.
