Abstract: A memory controller for reducing a time to create an address management table during initialization of a memory card. The memory controller includes a read-write memory for temporarily storing the address management table and a second memory controller for writing, in a nonvolatile memory, an address management table temporarily stored in the read-write memory. The second memory controller also writes address range specifying information that specifies an address range, when a data writing destination is changed from a first address range to a second address range. The memory controller includes an address management table generator for reading distributed management information used for managing a state of at least one physical block included in the destination address range specified by the address range specifying information during initialization, and to generate the address management table based on the distributed management information.

Abstract: For address management of a nonvolatile memory, the whole logical address space is divided into logical address ranges (0 to 15), and the physical address space is divided into physical areas (segments (0 to 15)). The logical address ranges are respectively associated with the physical areas (segments) to manage the addresses. The sizes of the logical address ranges are equalized. The size of the physical area (segment (0)) corresponding to the logical address range (0) in which data of high rewrite frequency such as an FAT is expected to be stored is larger than those of the other physical areas, and the logical address ranges and the physical areas are allocated. Alternatively, the sizes of the physical areas are equalized, and the size of the logical address range (0) is set as a smaller one than those of the other logical address ranges. With this, the actual rewrite frequencies of the physical areas (segments) are equal to one another, and consequently the life of the nonvolatile memory can be prolonged.

Abstract: With nonvolatile memory device employing a nonvolatile memory suc h as multiple-valued NAND flash memory or the like in which each memory cell holds data in a plurality of pages, there is such a problem that, if an error occurred under writing data, data stored in other page in the same group of the current page is changed, and hence the object of the present invention is to solve this problem. In writing data into a nonvolatile memory 110, when error occurred under writing data into a certain page, an error page identification part 128 identifies an error type and a physical address of the page where error occurred. An error corrector 129 then corrects errors occurred in other pages belonging to the same group of error occurrence page.

Abstract: A nonvolatile memory device includes a plurality of memory controllers. Each of the memory controllers has an aggregation processing part and an aggregation synchronization part. Based on a signal from the aggregation synchronization part, the aggregation processing part aggregates valid data of a temporary physical block into another physical block. When one of the memory controllers requires an aggregation process, the aggregation synchronization part sends a synchronization signal to the other memory controller, so that the aggregation process is simultaneously carried out by the other memory controller. Thus, in the nonvolatile memory device having a plurality of memory controllers, it is possible to reduce the time required for the aggregation process and carry out a high-speed writing process.

Abstract: An address at which a writing error occurs is held, and after a completion of a series of writings, the data of the held address is read. Then, a faulty-block processing is performed only for the addresses, for which it is determined that retry of writing is required, thereby preventing an increase of faulty-blocks. This can suppress the problem that when a writing is performed in a particular flash memory, a writing error frequently occurs and a large number of faulty blocks occur.

Abstract: When a control unit (160) in a storage device (100) detects that a write end command or a data amount to be written has been transmitted from a host device (110), the control unit (160) saves control information required for writing data in a control information save memory (142). The control unit (160) also saves data which has not been written in storage medium into a buffer save memory (152) from a data buffer (151) and releases the busy state for the host device (110). The control unit (160) writes the saved data into a storage medium (120). Even if the power is turned OFF before completion of write, write can be performed into the storage medium (120) by using the saved data when the power is turned ON next time.
