Abstract
To provided a relief-address generating circuit that generates relief address information based on plural data bits supplied in time sequence via a first terminal from outside and a programming circuit that writes into any one of fuse sets the relief address information generated by the relief-address generating circuit. With this configuration, repetition of a programming operation by the total number of the fuse sets at the maximum completes a series of write processing on relief address information. Therefore, it is possible to reduce the time required for a series of write processing on relief address information.
