Claim 15:
16. The method of claim 12, wherein:
each of the first and second verify operations further includes a first and second verify operation loop, wherein each of the first and second verify operation loops includes generating a verify voltage by the voltage generator and repeatedly providing the selected word line with the verify voltage,
wherein a voltage level of the verify voltages of each of the second verify operation loops decreases by a verify voltage decrement each time the verify voltage is provided,
wherein a voltage level of the verify voltage of the first verify operation loop of the second verify operation is higher than a voltage level of the verify voltage of the first verify operation loop of the first verify operation, and
wherein the verify voltage decrement of the first verify operation is different from the verify voltage decrement of the second verify operation.
