1. A master device to communicate with a slave device, the master device comprising:
a first pad connected to the slave device through a first wire;
a second pad connected to the slave device through a second wire; and
a communication interface to transmit a communication control signal to the slave device through the first pad, and, through the second pad, to transmit a first data signal synchronized with the communication control signal to the slave device and to receive a second data signal synchronized with the communication control signal from the slave device,
wherein the first data signal is transmitted to the slave device by the master device in a write mode and the second data signal is transmitted to the master device by the slave device in a read mode, and
wherein the communication interface is configured to start the read mode by transiting the communication control signal from a first voltage level to a second voltage level while the second pad has a predetermined voltage level.
