<P>PROBLEM TO BE SOLVED: To provide a semiconductor processing device such as a card type electronic device wherein a trouble by power supply interruption due to card drawing is relatively easily solved. <P>SOLUTION: This semiconductor processing device comprises an interface control circuit 4 and a processing circuit 5, and it is installed to an external device, e.g., a card slot 11, to receive an operating power supply. As a first form for solving the trouble by power supply interruption by card drawing, the interface control circuit detects a potential change caused in a first external terminal H1 which is separated, when the device is drawn from the card slot, from a predetermined terminal P1 prior to interruption of power supply from the card slot, and instructs an end processing to the processing circuit which is in operating state. Accordingly, the semiconductor processing device performs the end processing by itself before the power supply is perfectly interrupted. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
