A non-volatile memory device for performing a sensing operation using a current signal includes a cell array, a current-voltage converter, and a sense amplifier. The cell array includes at least one unit cell so as to read or write data. The current-voltage converter converts a sensing current corresponding to data stored in the unit cell into a sensing voltage, outputs the sensing voltage, receives a feedback input of the sensing voltage, and adjusts a level of a current applied to an input terminal of the sensing current in response to a level of the feedback input sensing voltage. The sense amplifier compares the sensing voltage with a predetermined reference voltage, and amplifies the result of comparison.
