摘要： 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.

摘要： A memory card has a plurality of non-volatile memories and a main controller for controlling the operation of the non-volatile memories. The main controller performs an access control to the non-volatile memories in response to an external access instruction, and an alternate control for alternating an access error-related storage area of the non-volatile memory with other storage area. In the access control, the speeding up of the data transfer between flash memories is achieved by causing the plurality of non-volatile memories to parallel access operate. In the alternation control, the storage areas is made alternative for each non-volatile memory in which an access error occurs.

摘要： The external storage device according to the present invention which uses a non-volatile semiconductor memory such as a flash memory is provided with plural areas which store user data, and restricts access to the user data from a host computer and also dynamically changes an area an access to which is to be restricted. Accordingly, the ease of use of the external storage device for the host computer is improved. Specifically, the interior of the flash memory is divided into a normal area not protected by a password or the like and a protected area protected by a password or the like. A microprocessor controls accesses to the normal area and the protected area in accordance with a command from the host computer. In addition, the host computer can access the protected area after passing through authentication using a password. Moreover, the host computer changes information indicative of the location of the protected area, thereby dynamically changing the protection area.
