ABSTRACT:
A memory control method for adjusting sampling points utilized by a memory control circuit receiving a data signal and an original data strobe signal of a memory includes: utilizing at least one delay unit to provide a plurality of sampling points according to the original data strobe signal; sampling according to the data signal by utilizing the plurality of sampling points; and analyzing sampling results to dynamically determine a delay amount for delaying the original data strobe signal, whereby a sampling point corresponding to the delayed data strobe signal is kept centered at data carried by the data signal.
