A display control device includes a detector, a frequency adjusting signal generator, a clock generator and an output timing generator. The detector compares an input field reference signal with an output field reference signal to determine a time difference signal. The frequency adjusting signal generator outputs a frequency adjusting signal. The clock generator outputs a clock according to the frequency adjusting signal. The output timing generator generates an output field synchronization signal according to the clock. The clock generator adjusts the frequency of the clock according to the frequency adjusting signal.

Display control device and method for controlling the same

The invention is directed to a memory controller and an associated signal generating method. By appropriately arranging a sequence according to which command signals are generated and expanding a latching interval of a part of address signals, not only the memory controller is enabled to control the DDR memory modules in a functional manner to further overcome issues of conventionally small latching intervals, but also system stability and access performance are reinforced as the memory access clock speed continue to increase.
