The inventive concept relates to a nonvolatile memory device and methods for operating the same. The nonvolatile memory device comprises a plurality of strings arranged in rows and columns on a substrate, each string including at least one ground select transistor, a plurality of memory cells and at least one string select transistor sequentially stacked on the substrate. The method comprises erasing first memory cells corresponding to an erasure failed row and inhibiting erasure of second memory cells corresponding to an erasure passed row, and performing an erasure verification by a unit of each row with respect to the first memory cells.

The operating method of a data storage device includes storing data in a buffer memory according to an external request, and determining whether the data stored in the buffer memory is data accompanying a buffer program operation of a memory cell array. When the data stored in the buffer memory is data accompanying the buffer program operation, the method further includes determining whether a main program operation on the memory cell array is required, and when a main program operation on the memory cell array is required, determining a program pattern of the main program operation on the memory cell array. The method further includes issuing a set of commands for the main program operation on the memory cell array to a multi-bit memory device based on the determined program pattern.
