Abstract
Disclosed are methods and circuits that support different on-die termination (ODT) schemes for a plurality of signaling schemes using a relatively small number of external calibration pads. These methods and circuits develop control signals for calibrating any of multiple termination schemes that might be used by associated communication circuits. The ODT control circuits, entirely or predominantly instantiated on-die, share circuit resources employed in support of the different termination schemes to save die area.
