Abstract:
An impedance code generation circuit includes a first code generation unit configured to compare a voltage of a calibration node with a reference voltage and generate a first impedance code, a code modification unit configured to generate a modified impedance code by performing an operation on the first impedance code according to a setting value, and a second code generation unit configured to generate a second impedance code based on the modified impedance code.
