Abstract
A writing completion flag table that stores a writing completion flag corresponding to a predetermined storage, such as a cluster or a physical block, is stored in a non-volatile control memory. When completion of data writing into a predetermined storage is detected, a write completion flag is written in the corresponding address of the storage on the write completion flag table. Thus, it is possible to recognize that data has been written normally. Even when the flag indicating completion of writing into a page of the writing unit of the main storage memory cannot be written, it is possible to improve the writing reliability.
