Patent ID: 8000148

Claim:
A method of operating a nonvolatile memory device including a plurality of memory cells, the method comprising: stabilizing recorded data by turning off a memory cell in which the recorded data is recorded and inducing a boosting voltage on a channel of the memory cell from a plurality of bit lines, the memory cell being selected from the plurality of memory cells, wherein the inducing of the boosting voltage includes, turning off the selected memory cell, turning on string select transistors that are at a first end of the plurality of memory cells and are between a plurality of bit lines and the plurality of memory cells, turning off ground select transistors that are at a second end of the plurality of memory cells and are between the common source line and the plurality of memory cells, and applying a first voltage to each of the plurality bit lines, the first voltage being transferred to the memory cells through the string select transistors, wherein the plurality of memory cells are arranged between the common source line and the plurality of bit lines on a semiconductor substrate, and wherein turning on the string select transistors includes, applying a third voltage to the string select transistors, and the third voltage is greater than or equal to the first voltage.
