Abstract
A semiconductor integrated circuit includes a chip address data designation circuit, which has nonvolatile circuit characteristics or nonvolatilely programmed wiring corresponding to a chip address assigned to each of semiconductor chips connected to common buses, to output first chip address data corresponding to the chip address upon receiving an operation power supply voltage. The semiconductor integrated circuit further includes a chip address data latch circuit for latching second chip address data supplied from outside to the semiconductor chip, and a chip selection control circuit for comparing the first chip address data and the second chip address data, and generating a chip selection signal for activating the semiconductor chip when the first chip address data and the second chip address data coincide with each other. The chip address assigned to each semiconductor chip can be stored nonvolatilely, and one of the chips can be selected in response to the chip address supplied from outside the chip.
