1. A method for operating non-volatile storage, comprising:

  • applying a plurality of voltages, one at a time, to a control gate of a selected non-volatile storage element; and

    while applying each voltage, coupling, to the selected non-volatile storage element, at least one current source;

    sensing a current which flows through the selected non-volatile storage element; and

    comparing the sensed current to a reference current which is different for at least two of the voltages, wherein the reference current is set according to different temperature coefficient versus current relationships of different data states.
