<P>PROBLEM TO BE SOLVED: To provide a DLL device for reducing an operating current for a DRAM by preventing that a DLL clock is meaninglessly toggled and ringed to sections other than a necessary section where the clock is actually used, not only in a power down mode or a self refresh mode but also in a normal mode operation. <P>SOLUTION: The DLL driver control circuit includes the DLL driver for driving the DLL clock and a DLL driver controller for generating a control signal to control the driving of the DLL driver in response to a signal having information associated with an active mode. <P>COPYRIGHT: (C)2007,JPO&INPIT |
