PROBLEM TO BE SOLVED: To provide a data transfer circuit whose data transfer rate is high and power consumption is low. SOLUTION: The data tranfer circuit is provided with a first selecting circuit for pre-charging the potentials of two signal lines among three signal lines and of residual one signal line, and a second selecting circuit for selecting and connecting two signal lines selected by the first selecting circuit to a receiving side circuit. Thereby, a pre-charge period of the signal line is included in a data transfer period so that a specific pre-charge period is not required after transfer of data, and that data transfer is accelerated.
