Abstract: A method for reading a data of a memory cell comprising a selection device and a resistive memory device which has a high resistance state or a low resistance state according to a data stored therein includes: applying a first read voltage to the memory cell; applying a second read voltage to the memory cell, the second read voltage having a level lower than a level of the first read voltage; and sensing the data of the memory cell while the second read voltage is applied to the memory cell.
