ABSTRACT:
A redundant decoder circuit includes a restoration circuit for restoring a decoder which activates a redundant memory cell. When the redundant memory cell which should store a predetermined information is disabled, the restoration circuit stops the decoder from supplying the active signal to the disabled memory cell. Therefore, the predetermined information is to be stored in another memory cell instead of the disabled memory cell, so that the redundant memory cell is used effectively.
