1. A signal width repair circuit, comprising:
a delay circuit, configured to receive an input signal, and delay the input signal for a preset duration to obtain a delayed signal, the input signal being a low-level signal;
a signal reconstruction circuit, configured to receive the input signal and the delayed signal, and repair the input signal and the delayed signal to obtain a repaired signal; and
a signal selection circuit, configured to receive the input signal and the repaired signal, and select one of the input signal and the repaired signal for output, to obtain a target signal that has a width satisfying a preset width, wherein the preset duration is equal to or greater than a duration with the preset width.
