PURPOSE:To reduce and shorten wiring by dividing an inspecting circuit and an error correcting circuit, connecting each inspecting circuit to error correcting circuit by a syndrome output line, checking errors by each inspecting circuit and syndrome output line, and correcting errors by each error correcting circuit. CONSTITUTION:Each information block 12 is connected from a sense amplifier 19 to error correcting circuits 21 through wiring 14, and at the same time, connected to error correcting circuits 21 through parity inspecting circuits 20 and a syndrome bus (output line) 22. The syndrome bus 22 connects the parity inspecting circuits 20 and inspecting blocks 13 to combine them successively and connected 6 to each error correcting circuit 21 branching successively. As the syndrome bus 22 is constituted of (n-k) bit wiring, chip are required for wiring can be made small, and concentration of wiring can be prevented.
