摘要:
Provided is a method for programming a nonvolatile memory device. The nonvolatile memory device includes a local word line to divide a memory cell string into a first area including a selected word line and a second area not including the selected word line. In the method, word lines of the first area are driven by a first pass voltage and word lines of the second area driven by a second pass voltage higher than the first pass voltage. A cell transistor corresponding to the local word line is turned off after the first pass voltage and the second pass voltage are applied. The selected word line is driven by a program voltage after the cell transistor is turned off.
