ABSTRACT:
A relief processing section which performs a relief process with respect to a redundant memory comprises a plurality of defect relief sections each having shift register circuits (relief information storing section). The shift register circuits are connected in series so as to successively transfer data. A test circuit tests the redundant memory, and serially outputs relief information for relieving a defective cell. The relief processing section stores the relief information into the shift register circuits using a data transfer operation thereof.
