  • Publication number: 20090079439
    Abstract: An eFuse system and a method for testing the eFuse system are provided. The eFuse system includes an eFuse, a sensing circuit, and an offset resistor. The sensing circuit has a trigger point resistance and is coupled to a first end of the eFuse for sensing the resistance of the eFuse, wherein the resistance depends on whether the eFuse is blown or not. Accordingly, the sensing circuit outputs a first signal if the sensed resistance is greater than the trigger point resistance and outputs a second signal if the sensed resistance is less than the trigger point resistance. The offset resistor is coupled to a second end of the eFuse for compensating a shift on the trigger point resistance of the sensing circuit due to temperature change.
