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 11):
The semiconductor apparatus of  claim 10 , wherein the first detection unit includes:\n a replica pull-up driver coupled between the power terminal and the internal reference resistor; and a comparator configured to generate the first pull-up impedance detection signal by comparing a level of a node to which the replica pull-up driver and the internal reference resistor are coupled with a level of a reference voltage.
