Nonvolatile memory device and data storage device including the same

摘要

A nonvolatile memory device includes: a plurality of memory cells arranged in a region where word lines and bit lines intersect, a data read/write circuit including a plurality of latches configured to temporarily store data inputted from an external device, and configured to perform a program operation on the memory cells based on data stored in the latches, and a skip data control unit configured to determine whether data to be programmed into the memory cells are available, and to store program-inhibit data in a latch corresponding to a memory cell which is determined to not contain any data.

1. A nonvolatile memory device comprising:
a plurality of memory cells arranged in a region where word lines and bit lines intersect; a data read/write circuit comprising a plurality of latches configured to temporarily store data inputted from an external device, and configured to perform a program operation on the memory cells based on data stored in the latches; and a skip data control unit configured to determine whether or not data corresponding to each of the memory cells is inputted, to determine a memory cell as a skip memory cell when data corresponding to the memory cell is determined not to be inputted, and to store program-inhibit data in a latch corresponding to the skip memory cell.
