Abstract:
An on-die termination includes: a code generator configured to generate a calibration code in response to a voltage of a first node and a reference voltage; a calibration resistor unit connected to the first node, and configured to be turned on and off in response to the calibration code; and a reference resistor unit coupled to the calibration resistor unit, and configured to be turned on and off in response to a control signal.
