Abstract:
A general-purpose logic module comprising:a first inverter in which an input is connected to a first node; a second node which is connected to an output of said first inverter; a second inverter in which an input is connected to a third node; a third inverter in which an input is connected to a fourth node; a first transfer gate in which an input is connected to the output of said first inverter, a first control input is connected to said fourth node, and a second control input is connected to an output of said third inverter; a second transfer gate in which an input is connected to an output of said second inverter, a first control input is connected to the output of said third inverter, and a second control input is connected to said fourth node; and a fifth node which is connected to an output of said first transfer gate and an output of said second transfer gate, wherein said general purpose logic module comprises a NAND circuit, wherein said third node and said fourth node are used as inputs and said fifth node is used as an output, and wherein said general-purpose logic module is formed by connecting said first node to a logic â€œ0â€  and setting said second node at a non-connection.
