Abstract

An impedance adjustment circuit includes a calibration circuit and a code update circuit. The calibration circuit performs an impedance adjustment operation to generate a source impedance code in response to activation of an impedance adjustment enable signal. The code update circuit performs a first channel code update operation to update a first channel impedance code according to the source impedance code when a first channel code update request signal is input, performs a second channel code update operation to update a second channel impedance code according to the first channel impedance code when a second channel code update request signal is input, and blocks the second channel code update operation when the second channel code update request signal is input while performing the first channel code update operation.
