Abstract:
An impedance calibration circuit includes a first detection unit configured to generate a first pull-up impedance detection signal according to a resistance value of an internal reference resistor, a second detection unit configured to generate a second pull-up impedance detection signal according to a resistance value of an external reference resistor coupled to an external reference resistor pad, a switching unit configured to select the first pull-up impedance detection signal or the second pull-up impedance detection signal according to the internal impedance calibration enable signal and output the selected pull-up impedance detection signal, and an impedance calibration signal generation unit configured to generate a plurality of impedance calibration signals according to an output of the switching unit.

Claim (Index 1):
A semiconductor apparatus comprising:\n a driving circuit configured to drive data and output a driving result outside the semiconductor apparatus by driving the data; a control circuit configured to internally generate a dummy impedance calibration command according to a voltage level of a power terminal; and an impedance calibration circuit configured to generate a plurality of impedance calibration signals by performing an impedance calibration operation using an internal reference resistor according to the dummy impedance calibration command and calibrate values of the plurality of impedance calibration signals by performing the impedance calibration operation using an external reference resistor when an external impedance calibration command is input.
