Patent ID: 8618812

Claim:
An integrated electrical interconnection device comprising: a plurality of electric terminals integrated on a pad area of a semiconductor chip and configured to be coupled to an integrated electronic circuit on the chip shared with said interconnection device; an input/output terminal integrated on the pad area of the semiconductor chip and configured to be electrically coupled to an external electronic device off of the chip; an adapter circuit integrated on the pad area of the semiconductor chip and configured to electrically couple the plurality of electric terminals to the input/output terminal, the adapter circuit including an inner electric device having a corresponding input coupled to a first terminal of said plurality and a corresponding output, the inner electric device being configured to provide a digital signal at the output; and a fault detecting logic module integrated on the pad area of the semiconductor chip and having a first input coupled to said output of the inner electric device and having a detecting terminal, the fault detecting logic module being configured to receive the digital signal, detect whether a fault exists on the interconnection device, and output from the detecting terminal a fault detecting signal representing whether the fault exists on the interconnection device.
