    摘要: 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.

    摘要: 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.

    摘要: With nonvolatile memory device employing a nonvolatile memory such 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.
