A method of controlling a memory card including a memory core and a memory controller,
- the method comprising:
- transmitting, in response to a first command, a response of status data that is used to determine whether the card supports a termination process, the termination process including shifting into a state ready for a stop of power supply from a host device;
- performing the termination process in response to a function stop command from the host device;
- transmitting a first signal indicative of a busy state while performing the termination process, the first signal being indicative of the busy state and having a first level;
- and
- notifying the host device of completion of the busy state by transmitting a second signal indicative of a ready state and having a second level when the memory card completes the termination process.
