摘要： An integrated circuit includes at least one circuit trimming fuse. A fuse sensor circuit is connected to the trimming fuse and operates in response to a fuse sensing initiation signal to initiate sensing of a state of the trimming fuse and generate an output indicative of the sensed state. A latch circuit, including multiple latch locations, redundantly latches the output indicative of the sensed state. A majority logic state in the latch locations is determined by a polling circuit coupled to the multiple latch locations. The polling circuit outputs that majority logic state as a fuse state output indicative of the sensed state of the fuse. A register in the integrated circuit is loadable with a value. A comparison circuit compares the loaded value in the register to a correct fuseword value and, if there is a match, generates the fuse sensing initiation signal for application to the fuse sensor circuit.
