1. A memory card connectable to a host, the memory card comprising:
a 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 first clock generator including a first voltage controlled oscillator (VCO) and configured to generate a second clock on the basis of the first clock; and
a controller configured to manage a state of the memory card, the state of the memory card including a first state and a second state, wherein
the first clock and the serial data are supplied to the receiver in the first state and are not supplied to the receiver in the second state, and
in the first state, the first clock generator is in an operating state,
in the second state, the first clock generator is in a non-operating state,
the controller is further configured to, in a first recovery mode, start receiving data or transmitting data from or to the host after a certain period of time after confirming a transition from the second state to the first state, without performing a handshake check.
