Claim 8:
9. The method of claim 8, wherein the at least one third voltage level comprises a first plurality of voltage levels and the at least one fourth voltage level comprises a second plurality of voltage levels, the method further comprising:
providing the verify voltage to the word line at the first plurality of voltage levels during the first verify operation; and
providing the verify voltage to the word line at the second plurality of voltage levels during the second verify operation,
wherein a voltage level of the second plurality of voltage levels is higher than a voltage level of the first plurality of voltage levels,
wherein voltage levels of each of the first plurality of voltage levels and the second plurality of voltage levels decrease as time increases during the first verify operation and the second program operation, respectively, and
wherein the voltage levels of the first plurality of voltage levels decrease at a different rate than the voltage levels of the second plurality of voltage levels.
