ABSTRACT:
A memory card includes a clock I/O circuit, a data I/O circuit, a delay element, and an adjustment value holding circuit. The clock input/output circuit receives a first clock from a host apparatus. The data I/O circuit receives a second clock from the host apparatus in a write timing adjustment mode. The data I/O circuit transmits and receives data to and from the host apparatus in a data transfer mode. In the write timing adjustment mode, the delay element adjusts a phase of the second clock in accordance with the first clock so as to receive the data received in the data transfer mode in response to the first clock. The adjustment value holding circuit holds an adjustment value for the phase of the second clock adjusted. In the data transfer mode, the delay element adjusts a phase of the data in accordance with the adjustment value.
