Abstract
A non-volatile memory device includes a cell array including a plurality of memory cells, a page buffer block controlling bitlines of the plurality of memory cells to program the memory cells to a first target state or a second target state, and a control logic configured to skip a verify operation for the memory cells programmed to the first target state and perform a verify operation for the memory cells programmed to the second target state during a second program loop when the memory cells programmed to the first target state are determined to be in a pass condition during a first program loop.
