Abstract: A method and circuit for controlling fuse blow including sending signals to a plurality of fuse latches, sending fuse select signals to a blow control circuit to determine if a fuse should be blown or not, activating a delay timer after a fuse is blown to control after-blow time. After the delay timer has expired, issuing a Stop signal that causes the blow control circuit to shut off a blow device. This process continues until successful blow completion of all to-be-blown fuses.
