Abstract

A method for reading data of a memory cell including a resistive memory element having a low resistance state and a high resistance state according to stored data and a selection element may include applying a recovery voltage to both ends of the memory cell, and applying a read voltage to both ends of the memory cell and sensing the data. The recovery voltage may be equal to or more than a second voltage obtained by adding a drift value of the memory cell to a first voltage for turning on the memory cell in a case in which the resistive memory element is in the low resistance state.
