  "textContent": "Embodiments of the present disclosure provide a circuit for controlling calibration, an electronic device, and a method for controlling calibration. The calibration control circuit includes an off-chip calibration module, an on-chip calibration module and a mode switching module. The off-chip calibration module is configured to receive and store a first calibration code sent by a user. The on-chip calibration module is configured to receive an enable signal and perform a ZQ self-calibration process on the memory to obtain a second calibration code adapted to a current environmental parameter in a case that the enable signal is in an active state. The mode switching module is configured to receive a calibration mode signal, the first calibration code and the second calibration code, and determine the first calibration code as a ZQ calibration code in the case that the calibration mode signal indicates an off-chip calibration mode, or, determine the second calibration code as the ZQ calibration code in a case that the calibration mode signal indicates an on-chip calibration mode.",
