Abstract

A non-volatile semiconductor memory device and method of programming the non-volatile semiconductor memory device are disclosed. The non-volatile semiconductor memory device includes a selected word-line and unselected word-lines including at least one unselected word-line to which a first voltage signal is applied. The selected word-line is coupled to a selected memory transistor and receives a program voltage signal in response to a program voltage enable signal. A first voltage signal is applied to the at least one unselected word-line. The first voltage signal has a voltage level of a reduced pass voltage signal before the program voltage enable signal is activated and has a voltage level of a pass voltage signal while the program voltage enable signal is activated.

Description

[0001] priority statement [0002] This application claims priority from Korean Patent Application No. 2006-99116 filed on October 12, 2006 in the Korean Intellectual Property Office, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to a nonvolatile semiconductor memory device and a method for programming it. Background technique [0004] Conventional semiconductor memory devices can be volatile or nonvolatile. In conventional volatile semiconductor memory devices, data is stored as a logic state of charge / discharge of a flip-flop or capacitor, and data can only be stored when power is applied, and is erased when power is turned off. [0005] Conventional nonvolatile semiconductor memory devices such as Electrically Erasable Programmable Read Only Memory (EEPROM) can store data even when power is turned off. Conventional non-volatile semiconductor memory devices can be used in many application fields,...
