Abstract

In a method of programming a non-volatile memory device, a first voltage is applied to a selected word line corresponding to a selected memory cell transistor of a selected transistor string to be programmed; a second voltage is applied to a neighboring word line neighboring the selected word line and corresponding to a neighboring transistor of the selected transistor string, wherein the first voltage is greater than the second voltage, the application of the first and second voltages to the selected and neighboring word lines respectively causing electrons to be generated by an electric field formed between the neighboring transistor and the selected memory cell transistor, the electrons accelerating toward the selected memory cell transistor and injecting into a charge storage layer of the selected memory cell transistor; wherein the neighboring transistor is positioned between the selected memory cell transistor and one of a ground select transistor and a string select transistor, and the first voltage is applied to unselected word lines corresponding to unselected memory cell transistors of the selected transistor string positioned between the selected memory cell transistor and the other of the ground select transistor and the string select transistor.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2008-0112237 filed on November 12, 2008, the entire contents of which are hereby incorporated by reference. technical field [0002] The present invention relates to a semiconductor memory device, and more particularly, to a programming method for a nonvolatile memory device. Background technique [0003] A flash memory (flash memory) device is a type of EEPROM that erases or programs multiple storage areas through one programming operation. A typical EEPROM only allows one area of ​​memory to be erased or programmed at a time, which means that flash memory devices can operate more efficiently at higher speeds than other memory areas that can be read and written simultaneously by systems using flash memory devices . After performing a certain number of erase operations, all types of flash memory devices and EEPROMs can fail due to aging of the charge storage device used to store data and damage to...
