Claims

[Scope of utility model registration request]

In an information processing device including a card body comprising a built-in nonvolatile memory connected to an external connection terminal without going through a microcomputer, and a card access tool for accessing the memory such as reading and writing. , the memory has a section size storage area for storing a data section size in addition to a data memory area for storing information data, and the card access tool is configured to store a section size storage area for storing data section size. a section size writing means for writing a section size in the section size storage area according to section size specification data; a section size reading means for reading the contents of the section size storage area; physical address calculation means for calculating a physical address of the memory corresponding to a section number according to a read result and external section number designation data; and access for accessing the memory based on the calculation result by the calculation means. An information processing device comprising a control means.
