Patent ID: 7990163

Claim:
An integrated circuit configurable to facilitate test of leakage current of externally accessible interconnects of the integrated circuit, the integrated circuit comprising: a first externally accessible interconnect; a second externally accessible interconnect; a first switchable device electrically coupled to the first externally accessible interconnect; a second switchable device electrically coupled to the first switchable device and to the second externally accessible interconnect such that when the first switchable device and the second switchable device are activated during a test mode of operation, a conductive path is formed from the first externally accessible interconnect and the second externally accessible interconnect, and wherein in a normal mode of operation, at least one of the first switchable device or the second switchable device is deactivated such that there is no conductive path between the first externally accessible interconnect and the second externally accessible interconnect; and registers arranged in a daisy chain and in communication with the first switchable device and the second switchable device to control activation thereof for leakage current testing.
