The method also includes controlling a chip enable signal associated with each of the memory devices according to the count values during a wait period following the providing the first burst of instructions until a second burst of instructions is provided to the memory devices. The chip enable signal of each of the memory devices defines clock cycles at which the memory device is operated and clock cycles at which the memory device is idle.
