Title:
IMPEDANCE CALIBRATION CIRCUIT, IMPEDANCE CALIBRATION METHOD AND MEMORY
Document Type and Number:
WIPO Patent Application WO/2023/245729
Kind Code:
A1
Abstract:
Provided in the embodiments of the present disclosure are an impedance calibration circuit, an impedance calibration method and a memory. The impedance calibration circuit comprises a parameter module, an initial value generation module and a calibration module, wherein the parameter module is configured to execute environmental detection processing, and output an environmental parameter signal; the initial value generation module is configured to receive the environmental parameter signal, and output an initial calibration value on the basis of the environmental parameter signal when a calibration instruction signal has been received; and the calibration module is configured to receive the initial calibration value, and perform impedance calibration processing on the basis of the initial calibration value when the calibration instruction signal has been received.
