Abstract:
An electric fuse cutoff control circuit controlling cutoff of a plurality of electric fuses including: a cutoff information storage circuit adapted to store cutoff information about whether or not each of the plurality of electric fuses is cut off; a cutoff information control circuit controlling the cutoff of the plurality of electric fuses based on an output signal of the cutoff information storage circuit; and a cutoff information renewal circuit receiving an output signal of the cutoff information control circuit and renewing the cutoff information set for the cutoff information storage circuit.
