Patent 7514976 was granted and assigned to Samsung on April, 2009 by the United States Patent and Trademark Office.
A pulsed flip-flop capable of adjusting a pulse width according to an operating voltage includes: a flip-flop operating in synchronization with a pulse signal; a pulse generating circuit generating the pulse signal in response to a clock signal; and a pulse width control circuit reducing a width of the pulse signal generated by the pulse generating circuit when the operating voltage is lower than a reference voltage.
