Abstract
A delay locked loop device (DLL) and an update method therefor are provided. The DLL device includes a DLL and an update circuit. The DLL is enabled according to an enable signal, thereby delaying an input clock to provide a delayed clock. The update circuit includes a flag generating circuit and an enable circuit. The flag generating circuit provides an update flag based on a default time interval. The enable circuit triggers the enable signal to a first logic level according to the update flag, and transitions the enable signal from the first logic level to a second logic level before the end of the default time interval. The default time interval is shorter than the refresh cycle of the memory.
