Abstract
The present disclosure provides a calibration circuit, a memory, and a calibration method. The calibration circuit includes: a calibration resistance module, wherein an output voltage of the calibration resistance module varies with a first parameter, and the first parameter includes at least one of a fabrication process of the calibration circuit, a power supply voltage of the calibration circuit, or an operating temperature of the calibration circuit; a reference voltage generation module, configured to receive a first comparison signal, to generate a corresponding reference voltage; and a comparison module, coupled to the calibration resistance module and the reference voltage generation module, and configured to compare the output voltage with the reference voltage and generate the first comparison signal.
