Abstract
A memory system may include a memory device and a memory controller. The memory device may be configured to store data. The memory controller may be configured to communicate with the memory device by an input/output driving circuit. The input/output driving circuit comprises a pull-down driver and a gate control logic. The pull-down driver may include a first transistor and a second transistor which are electrically coupled between a pad and a ground node. The gate control logic including a third transistor and a fourth transistor which are electrically coupled between the pad and a first terminal receiving a first driving voltage, the gate control logic being configured to receive a pad voltage provided from the pad and generate a feedback voltage. The source voltage level of the second transistor is controlled by a control signal generated based on a clock signal and an enable signal.
