PROBLEM TO BE SOLVED: To solve the problem that processing time for initialization is taken so much since data for initializing an EEPROM is prepared on a RAM in the conventional method. SOLUTION: In this system a nonvolatile memory can easily be initialized by preliminarily preparing an initialization data pattern 41 on a ROM 4 and initializing a specific data space existing the EERPOM 5 with the data pattern in the nonvolatile memory of an IC card. |
