Abstract
A method of operation of a non-volatile memory system including: providing a resistive storage element having a transformation layer; activating a write driver, coupled to the resistive storage element, for applying a bias voltage to the transformation layer; monitoring a resistance of the resistive storage element by a sense amplifier; and detecting a conductive thread, formed in the transformation layer, by the sense amplifier for reducing a level of the bias voltage.
