Patent attributes
A memory control device is disclosed that comprises a clock generator that generates a reference clock, a DLL circuit that receives the reference clock from the clock generator and outputs an output value indicative of a clock cycle of the reference clock, a delay setting circuit that receives the output value from the DLL circuit and outputs a delay setting value based on the output value according to at least one parameter, and plural delay elements that receive the delay setting value and introduce a delay responsive to the delay setting value. One or more of the delay elements receive input signals from corresponding one or more flip-flops driven by drive clocks generated by the clock generator, and send output signals to corresponding one or more output buffers that are to be connected to a memory.
