Benefits of technology

The patent text discusses a semiconductor system that includes a controller and a memory device connected through a signal transmission line. The controller has a calibration circuit that uses an external reference resistor to perform a calibration operation and set the resistance values of the output circuit. The memory device also has a calibration circuit that uses the external reference resistor to perform a calibration operation and set the resistance values of the output circuit. The technical effect of this system is to ensure accurate signal transmission between the controller and memory device through the signal transmission line.

Problems solved by technology

As semiconductor devices operate with low signal voltages and high operating frequencies, electronic signals are subject to the influence of noise, and impedance mismatching between semiconductor devices communicating with each other may lead to signal distortion.
