摘要： A driver impedance control apparatus and system for determining the impedance of at least one driver are provided. The driver impedance control apparatus includes a first reference impedance, a second reference impedance, a dummy pull-up array, a dummy pull-down array, a pull-up array control unit and a pull-down array control unit. The pull-up array control unit controls the pull-up impedance of the driver by detecting a voltage from a first voltage divide point between the first reference impedance and the dummy pull-up array. The pull-down array control unit controls the pull-down impedance of the driver by detecting a voltage from a second voltage divide point between the second reference impedance and the dummy pull-down array.
