    摘要: A nonvolatile memory device includes a memory block, a row decoder, a voltage generator and control logic. The memory block includes memory cells stacked in a direction intersecting a substrate, the memory block being divided into sub-blocks configured to be erased independently. The row decoder is configured to select the memory block by a sub-block unit. The voltage generator is configured to generate an erase word line voltage to be provided to a first word line of a selected sub-block of the sub-blocks and a cut-off voltage, higher than the erase word line voltage, to be provided to a second word line of the selected sub-block during an erase operation. The control logic is configured to control the row decoder and the voltage generator to perform an erase operation on the selected sub-block.
