Abstract
N-piece redundant address comparing circuits are individually composed of impedance converting circuits, so that information using redundancy is transmitted as an impedance value. Consequently, even though the N becomes larger as the capacity of a memory becomes larger, a signal line having large capacitance and the node of a redundant judging circuit are not charged or discharged. A high-speed operation can be realized without being affected by the capacitance of the signal line or by the capacitance of the node of the redundant judging circuit.
