A phase-locked loop circuit calibration method for a memory storage device including a rewritable non-volatile memory module is provided according to an exemplary embodiment of the disclosure. The method includes: receiving a first signal from a host system; generating a jitter signal by the memory storage device; generating a second signal according to the first signal and the jitter signal; performing a phase-lock operation on the second signal to generate a third signal by a phase-locked loop circuit; and calibrating an electrical parameter of the phase-locked loop circuit according to a variation of a time difference between the first signal and the third signal.
