Provided are a non-volatile memory device in which time required for programming may be saved, and a method of driving the same. The non-volatile memory device may include a memory cell array with a plurality of memory cells; an input/output buffer having a storage unit that stores data and indicator bits representing information regarding the data; a data scanning unit that receives the stored data from the input/output buffer in units of scanning, and that scans the received data, the received data being selectively programmed in the memory cells according to a result of scanning the data; and/or a control logic unit that controls the data stored in the input/output buffer in units of scanning to be selectively supplied to the data scanning unit based on the states of the indicator bits.
