摘要：
A semiconductor integrated circuit including a memory unit for storing address information of a failed circuit portion and for replacing the failed circuit portion by a redundant circuit portion. The semiconductor integrated circuit provides a comparison unit for detecting coincidence between data read from the memory unit and a received input address. Data produced from the comparison by the comparison unit is delivered through an external connection terminal.
