Semiconductor Memory Device and Its Control Method

摘要

A card information storage part ( 119 ) is provided in a semiconductor memory device ( 110 ) to store information of the characteristics of the semiconductor memory device ( 110 ). There is also provided a file system interface control part ( 120 ) for performing, based on the stored characteristic information, a file access suitable for the characteristics of the semiconductor memory device ( 110 ). This allows an access device ( 100 ) to perform an optimum file access via the file system interface control part ( 120 ) without awareness of the characteristics of the semiconductor memory device ( 110 ).
