NON VOLATILE MEMORY DEVICE AND OPERATING METHOD FO THE SAME

摘要

PURPOSE: A nonvolatile memory device and an operation method thereof are provided to execute a verify operation without failing a sensing operation by controlling a sensing bias voltage level according to temperature. CONSTITUTION: A temperature sensing part(610) generates a temperature sensing signal by sensing temperature. A microcontroller part(620) generates a sensing bias control signal in response to the temperature sensing signal. A voltage generating part(630) generates a sensing bias voltage in response to the sensing bias control signal. A connection part(120) electrically interlinks a bit line and a page buffer part in response to the sensing bias voltage.
