Patent ID: 8493121

Claim:
A reconfigurable flip-flop circuit, comprising: an input; a common output; a first storage element including an input thereto electrically coupled to the input through at least a first storage element input switch, and an output therefrom electrically coupled to the common output through at least at least a first storage element output switch; a second storage element including an input thereto electrically coupled to the input through at least a second storage element input switch, and an output therefrom electrically coupled to the common output through at least a second storage element output switch; control circuitry, the control circuitry configured such that during a first mode of operating, the control circuitry configures each of the first storage element and the second storage element to operate as latches in a dual-edge triggered flip-flop, and during a second mode of operating, the control circuitry configures the second storage element to operate as a latch in a master slave flip-flop; and a cross-storage element switch with a first terminal and a second terminal, the first terminal electrically coupled to the output of the first storage element and the second terminal electrically coupled to the input of the second storage element.
