    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.

    摘要: A non-volatile memory device is disclosed that can reduce the time required for the initialization process. A non-volatile memory device includes a non-volatile memory array having a plurality of pages. Each page includes a plurality of non-volatile memory cells, a first region for storing data, and a second region for storing control data that is associated with the data of the first region. The non-volatile memory device further includes a read out unit for reading out data from the pages, and a data buffer for temporarily storing data that has been read out from the pages by the read out unit. When reading out the control data, the read out unit reads out the second regions, across a plurality of pages, at one time.

    摘要: A control method of a non-volatile memory apparatus, which can execute data writing normally after the next startup even when a process is interrupted because of the occurrences of abnormal conditions such as power shut down during data writing or data erasing is provided. The control method of a non-volatile memory apparatus of the present invention comprises: a first flag writing step of writing a fixed value, which indicates that data is written, on a first flag existing in a redundancy area on a first page of a physical block and indicating whether or not data is written on the first page; and a data writing step of writing data on the physical block, when the data is written on the non-volatile memory consisting of a plurality of physical blocks.
