REFERENCE VOLTAGE GENERATING CIRCUIT, SEMICONDUCTOR DEVICE INCLUDING THE SAME AND METHOD OF GENERATING REFERENCE VOLTAGE

摘要

In order to supply a stable reference voltage, a plurality of reference voltage generator for generating a reference voltage which changes according to each of the termination voltage, a semiconductor device and a reference voltage generation method comprising same are disclosed. Reference voltage generating circuit being connected respectively to a plurality of terminating nodes and a plurality of end nodes providing the terminal voltage for each end through termination resistors of a plurality of data signals, to determine the logic level of the end of data signals It includes a plurality of reference voltage generator for generating a reference voltage which changes according to the respective termination voltage to. By providing each of the reference voltage which changes according to each of the terminal voltage of the data signal, it is possible to reduce the error rate when determining the logic level of the plurality of data signals. ; Reference voltage, the end voltage and terminating resistance, the open-drain driver, push-pull driver
