Abstract
An electronic apparatus and an electronic fuse (e-fuse) thereof are provided. The e-fuse includes a transistor and a voltage selector. A first end of the transistor receives a power voltage, and a second end of the transistor is coupled to a reference ground voltage. The voltage selector receives a programming voltage and a read voltage, and outputs the programming voltage or the read voltage to a control end of the transistor according to a control signal. Wherein, the control signal is used to indicate the e-fuse being operated in a programming mode or a read mode. When the e-fuse is operated in the programming mode, the programming voltage is provided to the control end of the transistor for damaging a gate oxide layer of the transistor.
