Abstract
An integrated circuit (IC), comprising a fuse structure (eFuse) formed in a resistive layer over a semiconductor substrate, the eFuse subject to a change in resistance through the controlled application of a programming current from a programming voltage source connected to a first terminal of the eFuse; a blow transistor formed on or over the substrate and having a control terminal configured to cause the programming current to flow through the eFuse in response to a programming signal; an intermediate transistor formed on or over the substrate and electrically coupled in series between a second terminal of the eFuse and the blow transistor; and, control circuitry formed on or over the substrate and electrically coupled to a node between the second terminal of the eFuse and the intermediate transistor, the control circuitry configured to reduce the flow of programming current through the eFuse in the event that a voltage detected at the node reaches a threshold level.
