    摘要: A method of programming a nonvolatile memory device may include applying a program voltage to a memory cell. A supplementary pulse may be applied to the memory cell to facilitate thermalization of charges after the application of the program voltage. A recovery voltage may be applied to the memory cell after the application of the supplementary pulse. A program state of the memory cell may be verified using a verification voltage after the application of the recovery voltage.
