ABSTRACT:
A semiconductor integrated circuit includes a main memory unit, a redundancy memory unit and a redundancy information file unit, wherein at least a part of data that would otherwise be stored in the main memory is stored in the redundancy memory unit according to redundancy information stored in the redundancy information file unit, thereby secrecy of the data stored in this manner is enhanced.
