    摘要: A nonvolatile memory device includes a memory cell array having multiple memory blocks. Each memory block includes memory cells arranged at intersections of multiple word lines and multiple bit lines. At least one word line of the multiple word lines is included in an upper word line group and at least one other word line of the multiple word lines is included in a lower word line group. The number of data bits stored in memory cells connected to the at least one word line included in the upper word line group is different from the number of data bits stored in memory cells connected to the at least one other word line included in the lower word line group.
