Abstract:
1. A programming method of a nonvolatile memory device, comprising: inputting even data and odd data to be programmed into even memory cells coupled to even bit lines and odd memory cells coupled to odd bit lines, respectively; setting a sense signal as a first sense signal or a second sense signal having a lower voltage level than the first sense signal, based on odd data of odd memory cells adjacent to each of the even memory cells to be programmed; programming the even data into the even memory cells by supplying the program voltage; performing a program verify operation on each of the even memory cells in response to the set sense signal; programming the odd data into the odd memory cells by supplying the program voltage, if as a result of the program verify operation on the even memory cells, the even memory cells are determined to have passed; and performing a program verify operation on the odd memory cells in response to the second sense signal.
