Abstract
A program method of a nonvolatile memory device includes applying a program voltage to a selected word line, applying a first pass voltage to at least one word line adjacent to the selected word line, applying at least one first middle voltage lower than the first pass voltage but higher than an isolation voltage to at least one word line adjacent to the word line receiving the first pass voltage, applying the isolation voltage to a word line adjacent to the word line receiving the first middle voltage, applying at least one second middle voltage higher than the isolation voltage but lower than a second pass voltage to at least one word line adjacent to the word line receiving the isolation voltage, and applying a second pass voltage to at least one word line adjacent to the word line receiving the second middle voltage.
