DATA ACCESS SYSTEM, ADDRESS CONVERSION METHOD, AND ADDRESS CONVERSION PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a system being capable of changing a memory capacity without modifying an address mapping table.SOLUTION: A data access system 10 of the present invention includes: a storage device 2 that stores data on a first surface 21 and second surface 22 that are continuous regions; an access device 1 that accesses the data on the first surface 21 and second surface 22 by specifying addresses where the data is stored; and an address conversion device 3 that converts the specified addresses and outputs them to the storage device 2 so that positions adjacent to a boundary between the first surface 21 and second surface 22 are address start positions of the first surface 21 and second surface 22.
