ABSTRACT:
A circuit with fuses and a semiconductor device having the same circuit include a first switch connected to a power supply voltage or a signal input terminal and turned on in response to a first pulse signal, a second switch connected to a ground voltage and turned on in response to a second pulse signal, a fuse connected between the first switch and the second switch, and a signal generating circuit for producing the first and second pulse signals. The first pulse signal turns off the first switch before the second pulse signal turns on the second switch and the first pulse signal turns on the first switch after the second pulse signal turns off the second switch.
