Zusammenfassung:A dynamic memory signal phase tracking method is provided. The method, applied to a memory controller that accesses a memory module, includes: issuing a memory access command and an access request to an arbiter to request for an access right of the memory module; when the access right is obtained, forwarding the memory access command to the memory module and asserting a flag signal; during a period of asserting the flag signal, sequentially using a plurality of candidate delay phases to adjust a memory signal for latching test data from the memory module, determining a delay phase according to latching results corresponding to the candidate delay phases, and recording the determined delay phases; updating an optimal delay phase according to the determined delay phase; and accessing the memory module according to the updated optimal delay phase.
