In a repair signal generating circuit, a first p-channel transistor has its source connected to a power supply, and a reset signal is input into its gate. An n-channel transistor has its source connected to a terminal of a grounded fuse, its drain connected to the drain of the first p-channel transistor, and the reset signal is input into its gate. A second p-channel transistor has its drain connected to the drains of the first p-channel transistor and the n-channel transistor, and its source connected to the power supply. The on-resistance of the second p-channel transistor is higher than that of the n-channel transistor. An inverter has its input terminal connected to the drains of the first p-channel transistor and the n-channel transistor, and its output terminal, where a repair signal is output, connected to the gate of the second p-channel transistor.
