Claim Text:
1. A non-transitory computer program product comprising a computer readable storage medium having computer readable program code stored thereon that, when executed by a computer, performs a method for detecting a state of a memory element in a memory device, the method comprising: applying, during a read operation of the memory element, a voltage pulse of a predetermined magnitude and duration to the memory element that is sufficient to induce a transition in the state of the memory element when a polarity of the pulse is opposite to the state; monitoring current passing though the memory element as a result of the applied voltage pulse to detect a presence or absence of a transition in the current that initially passes through the memory element; and determining the state of the memory element based on said monitoring, wherein the presence of a transition in the current is detected by a drop in the current that initially passes through the memory element, and the absence of the transition in the current is detected by substantially no drop in the current that initially passes through the memory element.
