A receiver circuit receives a signal from a semiconductor device. The receiver circuit includes an input buffer including a first plurality of transistors, the input buffer being configured to detect a fabrication condition of the receiver circuit, generate a control signal according to the detected fabrication condition, and control a gain of an input signal by adjusting a number of operating transistors among the first plurality of transistors in response to the control signal; and a latch circuit configured to latch an output signal of the input buffer, and adjust threshold voltages of a second plurality of transistors in response to a test signal.

Receiver circuit

An impedance calibration device for a semiconductor device includes a process sensor that detects a process condition for the semiconductor device and outputs a process signal, a temperature monitoring sensor that detects a temperature of the semiconductor device and outputs a temperature signal, a converter that converts the process signal and the temperature signal into a digital signal, and a code generation circuit that generates and outputs a driving code for controlling a level of a voltage at an output node according to the digital signal of the converter and a data signal. The impedance calibration device further includes an output driver that pulls up or pulls down the voltage at the output node according to the driving code.
