Abstract
A file management information area of a memory includes a FAT and a replacement information table. In the FAT, chain information on a file is recorded and in the replacement information table, replacement information of a defective area is recorded. In order to read out the file, a file system reads out the FAT and the replacement information table to generate indexes of the file and stores the indexes to an index buffer. In a memory controller, an address part of a read command is sequentially replaced with indexes stored in the index buffer and page-replaced read commands are continuously transferred to the memory.
