Abstract: An exemplary embodiment provides an equalizer adjustment method. The method includes: performing a handshake operation to establish a connection with a host system by a memory storage device; in the handshake operation, receiving a first signal from the host system and performing a first modulation on the first signal by the adaptive equalizer; after the handshake operation is ended, receiving a second signal from the host system and performing a second modulation on the second signal according to a modulation result of the first modulation by the adaptive equalizer to compensate the second signal; and adjusting the adaptive equalizer according to a modulation result of the second modulation.
