<p>A smartcard (1) has a memory (2) of a ROM portion (3) and an EEPROM portion (4). A first type of data will be required throughout the life of smartcard (1) is stored in ROM portion (3). A second type of program data which is to be used a predetermined number of times early on in the life of smartcard (1) is stored in EEPROM portion ( 4). Generally, the second type of data is stored in at least one lower memory address portion (8) of EEPROM (4). The second type of program data is moved from its lower memory address portion in EEPROM (4) to a higher memory address portion (9) for execution. The data is then deleted from higher memory address portion (9).</p> |
