Driver circuit having high reliability and performance and semiconductor memory device including the same

摘要

Example embodiments relate to a driver circuit and a semiconductor memory device including the driver circuit. The driver circuit includes a pull-up unit configured to connect an output node to a first power supply voltage in response to an input signal, an interface unit connected between the output node and a first node to decrease a voltage of the output node in response to a control signal, and a pull-down unit configured to connect the first node to a second power supply voltage. The interface unit includes a first transistor configured to connect the output node with the first node in response to the control signal and a first resistor connected between the output node and the first node. The interface unit may also include a second resistor and a second transistor connected in series between the output node and the first node.
