    • Disclosed herein is a device that includes a replica buffer circuit that drives a calibration terminal, a reference-potential generating circuit that generates a reference potential, a comparison circuit that compares a potential appearing at the calibration terminal with the reference potential, and a control circuit that changes an output impedance of the replica buffer circuit based on a result of a comparison by the comparison circuit. The reference-potential generating circuit includes a first potential generating unit activated in response to an enable signal and a second potential generating unit activated regardless of the enable signal, and an output node of the first potential generating unit and an output node of the second potential generating unit are commonly connected to the comparison circuit.

    • A semiconductor device includes a plurality of first chips, a second chip that controls the first chips, and internal wiring that connects the first chips and the second chip. The first chips each include: an optical fuse; a first latch circuit that retains information on the optical fuse; a second latch circuit that retains information on an electrical fuse, the information being supplied from the second chip through the internal wiring; and a select circuit that selects the information retained in either one of the first and second latch circuits. A redundancy determination signal is generated from the information selected. The information on the electrical fuse is transferred from the second chip to the first chips through the internal wiring.
