1. A method of controlling a memory card connectable to a host, the memory card comprising a host interface and a controller, the host interface including a receiver and a first clock generator, the receiver being configured to receive a first clock and serial data from the host, the method comprising:
generating a second clock on the basis of the first clock by the first clock generator;
managing states of the memory card, the states including an active state and a first dormant state;
supplying the first clock and the serial data to the receiver in the active state and not supplying the first clock and the serial data to the receiver in the first dormant state, wherein the first clock generator is in an operating state in the active state and the first clock generator is in a non-operating state in the first dormant state; and
in a first recovery mode, starting reception of data from the host or transmission of data to the host after confirming a transition from the first dormant state to the active state, without performing a handshake check.
