ABSTRACT:
An integrated circuit includes an array of state-change devices, first and second decoder circuits for selecting a particular state-change device. A voltage source is coupled to the first decoder circuit and sense circuitry is coupled to the second decoder to receive an electrical parameter from the selected state-change device and to detect a particular value of the electrical parameter. A control circuit is coupled to the voltage source, the first and second decoders, and the sense circuitry to select a first voltage from the voltage source to alter the selected state-change device and to select a second voltage from the voltage source when the sense circuitry detects the particular value of the electrical parameter.
