NON-VOLATILE STORAGE DEVICE AND WRITE METHOD THEREOF

摘要

It is possible to eliminate the defect that a long time is required for writing into a semiconductor memory card whose size is increased and the external data management size is different from the internal data management size in the semiconductor memory card. A partial physical block corresponding to the size managed externally is used regardless of the size of the physical block in a non-volatile storage device. Data is written in the partial physical block unit and an erase block is assured by the physical block unit, thereby increasing the write speed.
