Classification: CPC G  H | IPC G  H

Claim 13:
14. The nonvolatile memory device of claim 13, further comprising:
a control logic configured to control voltages applied to at least one of the plurality of memory cell strings such that, during a read mode,
the control logic is configured to apply a first voltage to an unselected memory cell for causing a current to flow only through the semiconductor layer of the unselected memory cell, and
the control logic being configured to apply a second voltage to a selected memory cell for causing a current to flow through all of the semiconductor layer, the dielectric film, and the resistance change layer of the selected memory cell; and
a bit line configured to apply a read voltage to the selected memory cell, wherein
the unselected memory cell and the selected memory cell are among the plurality of memory cells in the plurality of memory cell strings, and
the selected memory cell is in a selected memory cell string among the plurality of memory cell strings, and

wherein an absolute value of the second voltage is less than an absolute value of the first voltage.
