    摘要: To prevent stored information from being changed even at the occurrence of an abnormal condition in an upstream side of a system due to uncontrollable run of an OS. A nonvolatile storage means having data storage areas and management areas for them in units of predetermined physical addresses has an access protect definition table TLB in a predetermined physical address, and the table has access attribute information defining whether to permit or not access to the data storage areas in association with the physical addresses. The memory system itself possesses access attribute information defining whether to permit or not a write to and a read from the data storage areas in association with addresses to implement an access protect function for write and read. Therefore, the access protect function is maintained even if an abnormal condition occurs in a host device that manages the memory system or controls it as a peripheral circuit.

    摘要: A memory system permitting a number of alternative memory blocks to be made ready in order to extend the rewritable life and thereby contributing to enhanced reliability of information storage is to be provided. The memory system is provided with a nonvolatile memory having a plurality of data blocks in predetermined physical address units and a controller for controlling the nonvolatile memory in response to an access request from outside. Each of the data blocks has areas for holding a rewrite count and error check information regarding each data area. The controller, in a read operation on the nonvolatile memory, checks for any error in the area subject to the read according to error check information and, when there is any error, if the rewrite count is greater than a predetermined value, will replace the pertinent data block with another data block or if it is not greater, correct data in the data block pertaining to the error.

    摘要: The reliability of data is significantly increased without considerably increasing costs by performing minor data corrections within an information storage device and performing major error corrections in an information processing device. When a request to transfer user data for reading is issued from an information processing device, a control circuit transfers the user data and management data to an error detection circuit, which checks the user data for errors. If the user data contains no error, the control circuit notifies the information processing device that the user data can be transferred, and transfers it to the information processing device. If the user data contains errors, an X count error position and correction data calculation circuit uses the user data and the management data to calculate correction locations and correction data, and judges whether the correction locations are correctable. If uncorrectable (there are more correction locations than X locations), the control circuit notifies the information processing device that the user data is uncorrectable, and then transfers the user data and the management data to the information processing device.

    摘要: It is aimed to detect, notify, and save an abnormal area in semiconductor memory for greatly improving reliability. An inside of semiconductor memories provided for a memory card comprises a user area, a substitution area, an area substitution information storage area, and a management area. An inside of semiconductor memories comprises a user area, a substitution area, and a management area. The user area is a data area a user can use. The substitution area is substituted when an error occurs in the user area. The area substitution information storage area stores area substitution area information. The management area stores substitution information. The information processing section performs substitution on two levels as follows. When detecting an operation indicating a symptom of failure in a semiconductor memory area, the information processing section performs area substitution during an idle state of the memory card. When detecting a faulty operation in an area, the information processing section immediately performs area substitution.
