  • Patent number: 9413169
    Abstract: Circuits and methods for providing electrostatic discharge protection. The protection circuit may include a power clamp device, a timing circuit including a resistor and a capacitor that is coupled with the resistor at a node, a transmission gate configured to selectively connect the node of the timing circuit with the power clamp device, and a control circuit coupled with the node. The control circuit is configured to control the transmission gate based upon whether or not the capacitor is defective. The timing circuit may be deactivated if the capacitor in the timing circuit is defective and the associated chip is powered. Alternatively, the timing circuit may be activated if the capacitor in the timing circuit is not defective.

  • Patent number: 9070629
    Abstract: Methods and systems for altering the electrical resistance of a wiring path. The electrical resistance of the wiring path is compared with a target electrical resistance value. If the electrical resistance of the wiring path exceeds the target electrical resistance value, an electrical current is selectively applied to the wiring path to physically alter a portion of the wiring path. The current may be selected to alter the wiring path such that the electrical resistance drops to a value less than or equal to the target electrical resistance value.
