ABSTRACT:
A semiconductor device includes a relief-subject circuit, a relief circuit, and a plurality of fuse elements. The relief-subject circuit implements a predetermined function. The relief circuit is provided to relieve the relief-subject circuit in order to implement the predetermined function. The plurality of fuse elements are provided corresponding to the relief circuit in order to replace the relief-subject circuit with the relief circuit, thus storing information to specify the relief-subject circuit when this relief-subject circuit is replaced by the relief circuit.
