ABSTRACT:
A semiconductor circuit has at least one generator fuse for setting a supply voltage and at least one redundancy fuse for activating a redundancy element. A first read-out device is provided for reading out the generator fuse and a second read-out device reads out the redundancy fuse. The first read-out device is configured to read out the generator fuse at a first instant, and the second read-out device is configured to read out the redundancy fuse at a second instant.
