Abstract
A calibration method of an equalizer circuit for a memory storage device is disclosed. The calibration method includes: receiving a first signal; adjusting, by the equalizer circuit, the first signal according to a control parameter to output a second signal; generating a first sampling signal according to a first reference signal and the second signal, wherein the first sampling signal reflects data transmitted by the first signal; and generating a second sampling signal according to a second reference signal and the second signal and adjusting the control parameter according to the second sampling signal to calibrate the equalizer circuit, wherein a voltage value of the first reference signal is different from a voltage value of the second reference signal.
