ABSTRACT:
The device permits selection between two design options of an integrated circuit by causing a corresponding circuit unit of the integrated circuit to adopt one of two possible different operative states. More specifically, the device provides an inverter, of which the output terminal is connected to the control terminal of the circuit unit and the input terminal is connected to first and second supply terminals, via a conductor and a capacitor, respectively. The conductor can be broken by means outside the integrated circuit, and the capacitor is connected in parallel with a diode connected for reverse conduction. The device does not require control signals, takes up a very small area, has practically zero consumption, and can be formed in unlimited numbers on the same integrated circuit.
