Patent ID: 6937079

Claim:
A flip-flop circuit comprising: (a) a first branch having two transistors in series and a first branch source node, said first branch comprising a P-type transistor and an N-type transistor connected in series, the source of said N-type transistor being connected to said first branch source node and the drain of said P-type transistor being connected to a high potential; (b) a second branch having two transistors in series and a second branch source node, said second branch comprising a P-type transistor and an N-type transistor connected in series, the source of said N-type transistor being connected to said second branch source node and the drain of said P-type transistor being connected to said high potential, said second branch source node being common with said first branch source node; (c) a shared transistor having its source connected to said first branch source node and said second branch source node; (d) a pulse generator connected to the gate of said shared transistor; and (e) wherein the source of said first branch P-type transistor is connected to a first branch latch and the source of said second branch P-type transistor is connected to a second branch latch.
