摘要： It is possible to accurately detect a physical block which has caused a fixture defect in a flash memory so as to limit the use of the physical block. By recording a history of generation of a physical block error and a history of physical erasing in an ECC error record, it is judged whether the error which has occurred is accidental or caused by a fixture defect. When no error is caused in the data written by physical erasing after a first read error occurrence, the first error is accidental and if another error is caused, the error is judged to be caused by a fixture defect. By using such an ECC error record, it is possible to accurately judge whether the error is accidental or caused by a fixture defect. By eliminating use of the physical block judged to have a fixture defect, it is possible to reduce read errors.

摘要： Used is a nonvolatile memory such as a multi-level NAND flash memory having memory cells for holding data of a plurality of pages. When the data is to be written in the nonvolatile memory 110, a physical unit is consisted in units of a plurality of paired pages. When all the physical units cannot be written, the data is copied from an old physical block holding an already written effective data, and is written in a new physical block till the written, from the first section of a new physical unit, so that an error can be prevented.

摘要： A nonvolatile storage device includes a nonvolatile memory that stores data and a memory controller that controls the nonvolatile memory. The memory controller accepts a pause instruction to pause writing from the access device within a period in which data from the access device are written, and writes the data received from the access device to the nonvolatile memory within a predetermined time interval, then pauses the writing and accepts read and/or write of new data from the access device.

摘要： A plural-partitioned type nonvolatile storage device which solves the problem that a memory card composed of a flash memory and a controller, when a storage area is divided into a plurality of partitions, cannot be correctly used with a conventional host apparatus incapable of recognizing plural partitions. The memory card includes, as its storage areas, a device characteristic data storage area, a division table storage area, and a device storage area, where the device storage area is partitioned into plural partitions. The memory card can have different modes for adapting different accesses from the external host, and allows the external host to access partitions corresponding to the mode. Division information as to a dividing method for the plural partitions, and access information as to the host-accessible partitions corresponding to each individual mode are stored in the division table storage area. Plural types of device characteristic data corresponding to mode, respectively, are stored in the device characteristic data storage area.
