Abstract
A data input/output circuit includes a precharge voltage supply unit configured to supply a precharge voltage driven by a first internal voltage in a standby state, and supply the precharge voltage driven by a second internal voltage when an active operation is performed; and a precharge unit configured to receive the precharge voltage, precharge a first input/output line and a first inverted input/output line to a level of the first internal voltage in the standby state, and precharge the first input/output line and the first inverted input/output line by the second internal voltage when the active operation is performed.
