Output driver, and semiconductor memory device and memory system having the same
An output driver includes a pre-driver receiving a driver control code to generate a pull-up control signal or a pull-down control signal in response to data while a read operation is performed, an on-die termination controller receiving a first on-die termination control code to generate a first on-die termination control signal in response to an on-die termination enable signal while a write operation is performed, and a main driver including a pull-up n-channel metal-oxide-semiconductor (NMOS) driver generating high-level output data in response to the pull-up control signal while the read operation is performed, and terminating high-level input data with a first high voltage and terminating low-level input data with a first low voltage in response to the first on-die termination control signal while the write operation is performed, and a pull-down NMOS driver generating low-level output data in response to the pull-down control signal while the read operation is performed.
