A nonvolatile memory device includes; a memory cell array designating a first memory cell group including first memory cells connected with a word line and disposed less than a reference distance from a word line voltage source in a word line direction, and a second memory cell group including second memory cells connected to the word line and disposed more than the reference distance from the word line voltage source in the word line direction, and control logic configured during a data processing operation to provide a first word line voltage to a first target memory cell among the first memory cells, and a second word line voltage different from the first word line voltage to a second target memory cell among the second memory cells. |
