摘要: A method of programming a nonvolatile memory device comprises performing a first program operation on first memory cells and second memory cells so that threshold voltages of the first and second memory cells have a first reference level lower than a first target level, the first memory cells having the first target level as a first target level, and the second memory cells having a second target level higher than the first target level as a second target level; performing a second program operation on the second memory cells so that the threshold voltages of the second memory cells have a second reference level lower than the second target level; and performing a third program operation on the first and second memory cells to have the respective target levels.

摘要: A first verify voltage is applied to a word line of a selected memory cell, after a bit line is precharged, to program-verify the memory cell in a nonvolatile memory device. A first read evaluation operation for changing a voltage of the bit line is performed. Results of the first read evaluation operation are sensed using a first sensing voltage. A second read evaluation operation for changing the voltage of the bit line is performed again. Results of the second read verify operation are then sensed using the first sensing voltage.
