Abstract:
A circuit for the detection of a fuse with oxide vertical fusing has another fuse that is of the same type but cannot be blown and, in parallel with each of the fuses, a voltage reference circuit. The output of each of the voltage reference circuits is an input of a differential comparator. This differential comparator is preferably provided with a voltage reference circuit that is independent of the supply voltage Vcc.
