Claim 13:
14. A method of a flash memory controller to be used in a storage device and coupled to a flash memory device of the storage device through a specific communication interface, comprising:
providing an input/output (I/O) circuit for sending commands and data between the flash memory device and a processor; and
providing the processor for:
operating in a first mode to control the I/O circuit using a first set-feature signal, which carries a set-feature command, a first feature address of a first set-feature operation, and first feature parameter information, to the flash memory device to make the flash memory device execute the first set-feature operation based on the first feature address and the first feature parameter information after the first set-feature signal is received by the flash memory device; and
operating in a second mode to control the I/O circuit using and transmitting a macro start signal or a prefix signal to transmit second set-feature signals, respectively comprising the set-feature commands, second feature addresses of second set-feature operations, and second feature parameter information, to the flash memory device to make the flash memory device record the second feature addresses and the second feature parameter information into at least one storage unit of the flash memory device;
wherein the second feature addresses are different from each other.
