Control method for reading operation of memory device

A control method, for controlling a reading operation of a memory device, the control method comprising:

• providing a toggle signal to the memory device, the toggle signal has a toggle frequency;
• performing a reading operation of a page of the memory device according to the toggle signal, wherein the page includes a plurality of chunks;
• setting the toggle frequency as a target toggle frequency, and performing a reading operation of a first chunk of the page according to the target toggle frequency, so as to receive a data signal from the memory device;
• after the reading operation of the first chunk is completed, analyzing a latch margin of the data strobe signal with respect to the data signal according to a time difference between at least one check-point and a rising edge of the data strobe signal;
• determining a stable state of the data signal and the data strobe signal according to the latch margin;
• selectively adjusting the toggle frequency according to the stable state of the data signal and the data strobe signal;
• and
• performing a reading operation of a second chunk after the first chunk according to the toggle frequency which is adjusted.
