| 1. An integrated circuit having a switch comprising:
a first resistivity changing element;
a first reference element;
a second reference element; and
a sense amplifier, the sense amplifier configured to compare a signal from the first resistivity changing element to a signal
from the first reference element and to output a first signal based on the comparison for configuring the integrated circuit,
the sense amplifier further configured to compare the signal from the first resistivity changing element to a signal from
the second reference element and to output a second signal based on the comparison for configuring the integrated circuit.
