ABSTRACT:
A reprogrammable switch includes a first phase-change element, a first reference element, and a second reference element. The switch includes a sense amplifier for outputting a first signal based on a comparison of a signal from the first phase-change element to a signal from the first reference element and for outputting a second signal based on a comparison of the signal from the first phase-change element to a signal from the second reference element.
