ABSTRACT:
A semiconductor IC device such as a peripheral interface LSI device used in a data processing system comprises an address memory for storing the chip address of the device itself and a comparator for comparing an address signal input thereto from an external circuit with the content of the address memory. Address data existing on a bus line in an initial setting status is previously stored in the address memory as a chip address of the device. The device enters a chip selected condition depending on the coincidence between the address signal from the external circuit and the content of the address memory.
