Semiconductor memory device and related method of programming |
摘要 |
A method of programming a nonvolatile memory device comprises applying a program voltage to a selected wordline to program selected memory cells, and performing a verify operation by applying a verify voltage to the selected wordline to determine the programming status of the selected memory cells. The verify operation applies the verify voltage to the selected wordline at least two different times to divide the selected memory cells into at least three regions corresponding to different threshold voltage ranges.
