Abstract
Integrated circuit devices are provided including a pair of differential I/O lines and a driver circuit. The driver circuit is configured to drive the pair of differential I/O lines responsive to a write command signal. First and second precharge circuits are also provided. The first precharge circuit is configured to precharge the pair of differential I/O lines to a first voltage during a first mode of operation responsive to an active command signal. The second precharge circuit is configured to precharge the pair of differential I/O lines to a second voltage, lower than the first voltage, during a second mode of operation responsive to the active command signal. Related methods of operating integrated circuit devices are also provided.
