    Abstract: In a method of programming in a nonvolatile memory device, channels of a plurality of cell strings are precharged through ground selection transistors by a precharge voltage of a source line. A turn-on voltage is applied to a selected ground selection transistor of a selected cell string among the plurality of cell strings, during a verification read period of an N-th program loop. The turn-on voltage applied to the selected ground selection transistor is maintained to precharge the channels for an (N+1)-th program loop, without recovery after the verification read period of the N-th program loop is finished. Power consumption is reduced and an operation speed is increased by maintaining the turn-on voltage of the selected ground selection line to precharge the channels of the cell strings without recovery after the verification read operation is finished.

    Abstract: In a method of programming a three-dimensional nonvolatile memory device, a program loop is executed at least one time, wherein the program loop includes a programming step for programming selected memory cells among the memory cells and a verifying step for verifying whether the selected memory cells are program-passed or not. In the programming the selected memory cells, a level of a voltage being applied to a common source line connected to the strings in common may be changed. Thus, in a program operation, power consumption which is needed to charge-discharge the common source line can be decreased while increasing boosting efficiency.
