Patent ID: 7760550

Claim:
A method of reading data from a non-volatile memory device, comprising: applying a bit line read voltage to a bit line electrically connected to a selected cell located in a selected string; applying a selected cell read voltage to a word line electrically connected to the selected cell; applying a first read voltage to word lines electrically connected to first non-selected cells in the selected string, the first non-selected cells being separated from the selected cell; applying a second read voltage to word lines electrically connected to second non-selected cells in the selected string, the second non-selected cells being adjacent to the selected cell, the second read voltage inhibiting a fringe field affecting a threshold voltage of the selected cell and being substantially lower than the first read voltage; applying a pass voltage to a string select line and a ground select line, electrically connected to the selected string, for turning on a string select transistor and a ground select transistor, respectively; and comparing an electrical signal output from the selected string with a standard signal to read data stored in the selected cell.
