Abstract: Disclosed herewith is a semiconductor processing system such as a card type electronic device, which can easily cope with an error caused by power shutoff that occurs when the card is ejected. The semiconductor processing system is provided with an interface control circuit and a processing circuit and receives operation power from an external device such as a card slot when it is inserted therein. According to a first aspect of the present invention for coping with an error caused by power shutoff that occurs when the card is ejected, the interface control circuit, when the card is ejected from the card slot, detects a potential change to occur at a first external terminal to be disconnected from a predetermined terminal of the card slot before the power supply from the card slot is shut off, then instructs the processing circuit that is active to perform an ending processing. The semiconductor processing system can end the processing by itself before the power supply stops completely.
