Title:
CALIBRATION CONTROL CIRCUIT, ELECTRONIC DEVICE AND CALIBRATION CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2023/206634
Kind Code:
A1
Abstract:
Provided in the embodiments of the present disclosure are a calibration control circuit, an electronic device and a calibration control method. The calibration control circuit comprises: an off-chip calibration module, configured to receive and store a first calibration code sent by a user; an on-chip calibration module, configured to receive an enable signal, and, when the enable signal is in a valid state, to perform ZQ self-calibration processing on a memory, so as to obtain a second calibration code suitable for a current environment parameter; and a mode switch module, configured to receive a calibration mode signal, the first calibration code and the second calibration code, and to determine the first calibration code as a ZQ calibration code when the calibration mode signal indicates an off-chip calibration mode, or to determine the second calibration code as the ZQ calibration code when the calibration mode signal indicates an in-chip calibration mode.
