Abstract: A fuse protection and fuse blowing circuit includes a fuse register which has an additional fuse with respect to other fuse registers used in the system. The additional fuse has an output which indicates a blown/not blown state of the additional fuse, and that output is fed back to a blow enable input of each of the other fuses in the fuse register and the other fuse registers. When the additional fuse is set to the blown state, none of the other fuses are allowed to be blown, thereby protecting the device against any accidental blowing of fuses.
