A method of operating an integrated circuit including an output driver. The method includes storing a value in a register, wherein the value is representative of a voltage swing setting of an output driver. The voltage swing setting of the output driver is adjusted using a counter that holds a count value representing an update to the voltage swing setting. The count value is updated in accordance with a signal that indicates an adjustment to the voltage swing setting. In addition, an integrated circuit memory device comprising an output driver, a register and a counter is provided. The counter updates a count value in response to a signal that indicates a direction to adjust the count value.
