ABSTRACT:
A Delay Locked Loop (DLL) driver control circuit is capable of reducing an amount of current consumption by preventing the output of unnecessary clocks. The DLL driver control circuit includes a DLL driver for driving a DLL clock and a DLL driver controller for generating a control signal to control an operation of the DLL driver in response to a signal having information associated with an active mode. The DLL driver controller is provided with a counter for counting the DLL clock to produce a count a setting value having a plurality of bits and generating an activated equal signal if the two values are the same, and an SR latch for accepting the equal signal and the signal having the information associated with the active mode to provide the control signal.
