Abstract
A memory device includes a terminal calibration circuit having at least one of a pull-down circuit or a pull-up circuit used in calibrating an impedance of a data bus termination. The memory device also includes a reference calibration circuit configured to generate a calibration current. The terminal calibration circuit can be configured to program an impedance of the least one of a pull-down circuit or a pull-up circuit based on the calibration current.
