Claim Text:
1. A resistance memory, comprising: a conductive-bridging resistance memory cell, comprising: a circuit to apply across the resistance memory cell a set voltage pulse having a set polarity to set the resistance memory cell to a low-resistance state that is retained after application of the set voltage pulse, a reset voltage pulse having a reset polarity, opposite to the set polarity, to reset the resistance memory cell to a high-resistance state that is retained after application of the reset voltage pules, wherein the reset voltage pulse exhibits a magnitude that is larger than a magnitude of the set voltage pulse, the circuit to apply a read voltage pulse of the reset polarity and smaller in magnitude than the reset voltage pulse to determine the resistance state of the resistance memory cell without changing the resistance state of the resistance memory cell.
