Semiconductor devices and data processing systems

Abstract

This invention provides a high-speed semiconductor device. The semiconductor device includes: electrodes for data input and output; pull-up and pull-down circuits that control the voltage of the electrodes; internal circuitry that outputs data via the electrodes and inputs data via the electrodes; a control circuitry capable of performing operations on the internal circuitry and calibration operations such as adjusting the impedance of the pull-up and pull-down circuits; and a temperature sensor that supplies temperature data to the control circuitry. During the execution of the internal circuitry, the control circuitry acquires temperature data from the temperature sensor and performs calibration operations based on the acquired temperature data.
