摘要： An address identifying memory block is match-compared with address information stored in a to-be-remedied block memory section in a block redundancy judge section. A redundant block select signal is outputted from the block redundancy judge section by judgment of address match. A memory block column select section selects a memory block column having a redundant memory block irrespective of an address signal as the redundant block select signal is activated if block redundancy is activated to output a memory block column select signal. A column redundancy memory section selects address information of column redundancy relating a redundant memory block arranged in a memory block column in accordance with the memory block column select signal.
