摘要：
In a method of driving a nonvolatile memory device a first data state is determined from among the plurality of data states. The number of simultaneously programmed bits is set according to the determined first data state and a scanning operation is performed on data input from an external device to search data bits to be programmed. The searched data bits are programmed in response to the number of simultaneously programmed bits. The number of simultaneously programmed bits corresponding to the first data state is different from a number of simultaneously programmed bits corresponding to at least a second of the plurality of data states.
