Abstract: A method and apparatus for dynamically monitoring, measuring, and adjusting a clock duty cycle of an operating storage device is disclosed. A storage device includes a measuring circuit comprising a plurality of flip flop registers coupled to a first input line, with each flip flop register having a first input and a second input. One or more delay taps are coupled to each flip flop register, and are disposed on a second input line. While the device operates, a clock signal is input directly into the first input of each flip flop register via the first input line. Simultaneously, the clock signal is input into the second input of each flip flop register through the one or more delay taps via the second input line. The flip flop registers are then read to determine the clock duty cycle of the device, and the clock frequency is adjusted as needed.
