THE NON VOLATILE MEMORY DEVICE AND METHOD FOR PROGRAMMING AND METHOD FOR READING THEREOF

摘要

PURPOSE: A nonvolatile memory device and a programming/reading-out method thereof are provided to improve the threshold voltage distribution of a cell by reducing a program current after reducing the number of a program cell. CONSTITUTION: A data storage part(110) stores input data. A data counting part(120) outputs a counting signal according to the number of first data. A page buffer part(130) temporarily saves the input data that is saved in the data storage part. The page buffer part comprises a cache latch and a main latch. A control part(140) outputs a control signal by comparing the counting signal and a predetermined number.
