Patent ID: 6924671

Claim:
A method of configuring a logic gate from a general-purpose logic module, said logic gate performing a logic operation on first and second input signals to produce an output signal, said general-purpose logic module including first, second, third, fourth, fifth and sixth nodes, a first inverter connected between said first and second nodes, a second inverter connected between said third and fourth nodes, a first transfer gate connected between said second node and said fifth node and having a first control node connected to said sixth node, a second transfer gate connected between said fourth node and said fifth node and having a second control node, and a third inverter connected between said sixth node and said second control node of said second transfer gate, said first and second transfer gates being rendered respectively conductive and nonconductive when said sixth node is at a first logic level and rendered respectively nonconductive and conductive when said sixth node is at a second logic level, the method comprising: supplying said first input signal to said sixth node; supplying said second input signal to one of said first to fourth nodes; and deriving said output signal from said fifth node.
