Abstract:
A driving method of a nonvolatile memory device includes receiving a program command and an address. The method includes changing a number of adjacent zones of a plurality of zones formed of unselected word lines according to a location of a selected word line corresponding to the received address. The method further includes applying different zone voltages to the number of adjacent zones and remaining zones. The nonvolatile memory device includes a plurality of strings formed to penetrate word lines stacked on a substrate in a plate shape.
