A memory controller receives an application identifier for identifying an application from an outside, an application, reference data to be referenced by the application, and a signature for the application and writes the application and the reference data. After receiving the application identifier from the outside, the memory controller accesses memory means which manages the application identifier and the application management state and reads out the management state of the target application. According to the management state, necessary data is decided. Since the judgment result is informed to the outside, there is no need of receiving applications more than necessary and it is possible to reduce the load on the signature process and the application reception process. |
