ABSTRACT:
In a redundancy method, a redundancy switch is shared by a plurality of redundancy objects. The redundancy switch is divisionally, independently connected to recovery lines in the redundancy objects by a plurality of redundancies in the redundancy switch. Defects generated in the redundancy objects are replaced with information of the recovery lines in the redundancy objects that are connected to the redundancy switch, thereby recovering the defects. A semiconductor circuit for the above method is also disclosed.
