Abstract
A smart card compares an object identification parameter associated with a write command with an object identification parameter stored in the non-volatile memory of the smart card. If the comparison is positive, the data embedded in the write command is written at a at a predefined address whose value is stored in the non-volatile memory, an address corresponding to the sum of the stored predefined address and the size of the written data is calculated, and the calculated address is stored in the non-volatile memory in place of the predefined address. If the comparison is negative, the data is written at a default address, an address corresponding to the sum of the default address and the size of the written data is calculated, and the calculated address is stored in the non-volatile memory as the predefined address.
