Abstract: The present invention provides a nonvolatile memory card in which a program is added, modified, changed, or the like by selecting arbitrary firmware on a flash memory from a plurality of pieces of firmware on flash memories. In a memory card, in addition to a program stored in a built-in ROM, firmware on flash memories as programs for adding, changing, modifying, or the like of a function such as a patch program are stored. Firmware on a flash memory which is desired to be made valid is set in a parameter sector or the like and is loaded into an external RAM, and the CPU of a control logic executes a process.
