| Zusammenfassung: | A data output driving circuit includes a plurality of driving units that are set to have different impedance values from one another, and the number of driving units is less than the number of a plurality of required driving impedance values such that the driving units can obtain the plurality of required driving impedance values by a combination thereof, and a driving control unit that independently controls the operation of the plurality of driving units so as to obtain the plurality of driving impedance values required. |
