    Abstract: A nonvolatile memory device includes a nonvolatile memory cell array, where N bits are stored in a single memory cell (N being an integer greater than or equal to 2), and a page buffer circuit electrically connected to the nonvolatile memory cell array. The page buffer circuit includes at least N latches configured to temporarily store data. A data input/output circuit connected to the page buffer circuit receives programmed input data and provides the input data to the page buffer circuit. A control logic controls the page buffer and initializes a target latch value before receiving all input data of a program unit from the data input/output circuit.

    Abstract: Disclosed is a memory device includes a memory block that is connected with a plurality of wordlines, a voltage generating circuit configured to output a first non-selection voltage through a plurality of driving lines, and an address decoding circuit configured to connect the plurality of driving lines with unselected wordlines of the plurality of wordlines. During a wordline setup period for the plurality of wordlines, the voltage generating circuit floats first driving lines corresponding to first unselected wordlines of the unselected wordlines from among the plurality of driving lines when the first unselected wordlines reach a first target level, and floats second driving lines corresponding to second unselected wordlines of the unselected wordlines from among the plurality of driving lines when the second unselected wordlines reach a second target level different from the first target level.
