  • ACCESS CONTROL METHOD AND DATA STORAGE DEVICE
    Publication number: 20150253996
    Abstract: In an access control method of an embodiment, a first arithmetic unit writes a file in a first non-volatile storage region that can be accessed by the first arithmetic unit and cannot be accessed by a second arithmetic unit. Then, when the first arithmetic unit is started next time, the first arithmetic unit copies the file from the first non-volatile storage region to a second non-volatile storage region before the second arithmetic unit recognizes the second non-volatile storage region. Further, after the copy, the second arithmetic unit recognizes the second non-volatile storage region.
