摘要： The invention provides a data storage device and a method of updating management information, capable of dealing with management information in a highly reliable manner so that information is not easily lost when an error occurs. File management information such as a FAT serving as address management information in a flash memory is stored in a management information area of the memory, a pair of blocks is assigned as blocks for use to store data of the FAT, and writing of updated FAT information is performed by alternately using the two blocks of the block pair such that previous FAT information is retained in one of the two blocks of the block pair, and updated FAT information is written in the other block of the block pair, whereby, even when an error occurs in the middle of the process of writing the updated management information, a process using the retained previous FAT information is possible.

摘要： Memory control apparatus, memory control method, and program are provided. The present invention provides a preparatory process for determining whether or not a data-updating process to update data of a flash memory or a data-writing process to write new data into the memory has been completed normally. A data-updating process to update data stored in a specific block is carried out as a process including alternate-block processing to replace the specific block with another block referred to as an alternate block. In the current data-updating process, the alternate block is examined to determine whether or not data has been erased from the alternate block. If data has been erased from the alternate block, the preceding data-updating or data-writing process is determined to be normal. By virtue of a property exhibited by the contents of the reserved-block address, the reserved-block address needs to be saved in the flash memory only once during a data-updating or data-writing process.
