Zusammenfassung:PURPOSE: A nonvolatile memory device and a controlling method thereof are provided to improve a program speed by changing a pulse voltage. CONSTITUTION: A memory cell array(100) includes a nonvolatile memory cell. A sense amplifier(300) senses a memory cell state. A write driver loads data on the memory cell array. A control unit(200) controls the sense amplifier and the write driver and changes a pulse voltage applied according to a plurality of preset verification voltages in a program operation.
