ABSTRACT:
A system including an integrated circuit memory device. The integrated circuit device comprises a register to store a value representative of an output voltage setting. A circuit holds a value representative of an adjustment to the output voltage setting. An output driver outputs a drive voltage during a calibration operation, wherein a signal is generated based on a comparison between a signal derived from the drive voltage and a reference voltage. The signal updates the value representative of the adjustment to the output voltage setting.
