    Abstract: A method of erasing a non-volatile memory device which includes a plurality of NAND strings is provided as follows. A first voltage is applied to each of word lines for a corresponding effective erasing execution time. An erase operation is performed on memory cells connected to each of the word lines for the corresponding effective erasing execution time. A second voltage is applied to each of at least some word lines among the word lines for a corresponding erasing-prohibited time after the corresponding effective erasing execution time elapses. A sum of the corresponding effective erasing execution time and the corresponding erasing-prohibited time for each of the at least some word lines is substantially equal to an erasure interval during which an erase operation is performed using the first voltage and the second voltage higher than the first voltage. The word lines are stacked on a substrate.

    Abstract: A nonvolatile memory device includes a memory cell region, a peripheral circuit region, a memory block in the memory cell region, a row decoder in the peripheral circuit region, and a control circuit in the peripheral circuit region. The memory cell region includes a first metal pad. The peripheral circuit region includes a second metal pad and is vertically connected to the memory cell region by the first metal pad and the second metal pad. The memory block includes memory cells stacked in a direction intersecting a substrate, and is divided into a plurality of sub-blocks configured to be erased independently. The row decoder selects the memory block by units of a sub-block. The control circuit receives a data erase command for a selected sub-block among the plurality of sub-blocks, performs a data read operation on at least one victim sub-block among the plurality of sub-blocks in response to the data erase command, selectively performs a soft program operation on the at least one victim sub-block based on a result of the data read operation, and performs a data erase operation on the selected sub-block after the data read operation is performed and the soft program operation is selectively performed.
