Abstract
A memory apparatus includes a write driver, a sense amplifier and a reference voltage setting circuit. The write driver programs a set data or a reset data into a memory cell. The sense amplifier generates an output signal by sensing data stored in the memory cell. The reference voltage setting circuit sets a set reference voltage having a lowest level to satisfy a set data distribution, and sets a set-up reset reference voltage from the set reference voltage.
