Abstract:
A method and an apparatus for self-calibration of a driving capability and a resistance of an on-die termination are provided. The apparatus includes an output interface physical layer (PHY) and a ring oscillator. The output interface PHY receives an operation voltage. The ring oscillator surrounds the output interface PHY to sense a work temperature or the operation voltage and accordingly outputs a sensing result. The driving capability or the resistance of the on-die termination of the output interface PHY is adjusted according to the sensing result.
