Abstract

A method is provided for driving a nonvolatile memory device, including multiple strings, where each string is formed by penetrating plate-shaped word lines stacked on a substrate. The method includes configuring the word lines of a string in multiple zones based on zone configuration information, and applying zone voltages to the zones, respectively. The zone configuration information is varied according to a mode of operation.
