Abstract
A precharge circuit of a semiconductor memory device may include a precharge controller, a first precharge unit and a second precharge unit. The precharge controller may enable a first control signal in a precharge mode for a first operation, and may enable a second control signal in a precharge mode for a second operation. The first precharge unit may precharge a pair of I/O lines to a first voltage in response to the first control signal in the precharge mode for the first operation. The second precharge unit may precharge the pair of I/O lines to a second voltage lower than the first voltage in response to the second control signal in the precharge mode for the second operation.
