Abstract:
A termination resistance circuit includes a control signal generator for generating a control signal whose logical value changes when a calibration code has a predetermined value, a plurality of parallel resistors which are respectively turned on/off in response to the calibration code, and a resistance value changing unit for changing the total resistance value of the termination resistance circuit in response to the control signal.
