Abstract
A precharge circuit may include a precharge control unit, a first precharge unit, and a second precharge unit. The precharge control unit may generate a read precharge signal and a write precharge signal in response to a read signal, a write signal, and a precharge signal. The first precharge unit may precharge a data input/output line to a first voltage level in response to the read precharge signal. The second precharge unit may precharge the data input/output line to either a second voltage level or a third voltage level in response to the write precharge signal.
