Claim 2:
3. A secure memory card, comprising:
a non-volatile memory device for storing data, including a regular range of addresses and a reserved range of addresses;
a secure element for conducting a securing operation; and
a non-volatile memory controller in communication with the non-volatile memory device and the secure element, adapted to receive a command from a host,
wherein the non-volatile memory controller interacts with the secure element to conduct the securing operation in response to the command from the host if the command from the host is secure-element control command, which is a single command taking a single instruction cycle and corresponding to a specific address belonging to the reserved range of addresses, and the non-volatile memory controller interacts with the non-volatile memory device while having no interaction with the secure element in response to the command from the host if the command from the host is a non-secure-element control command corresponding to a regular address belonging to the regular range of addresses, and
wherein when the secure-element control command is a write command containing a first specific data to be written into a third specific address belonging to the reserved range of addresses, the securing operation is that a firmware of the non-volatile memory controller recognizing the third specific address revises a set of parameters of the secure element according to the first specific data.
