Abstract
Abstract A microelectronic integrated circuit includes a semiconductor substrate, and a plurality of CMOS microelectronic devices formed on the substrate. Each device includes a triangular ANY element of a first conductivity type (PMOS or NMOS), and a triangular ALL element of a second conductivity type (NMOS or PMOS), the ANY and ALL elements each having a plurality of inputs and an output that are electrically interconnected respectively. The ANY element is basically an OR element, and the ALL element is basically an AND element. However, the power supply connections and the selection of conductivity type (NMOS or PMOS) for the ANY and ALL elements can be varied to provide the device as having a desired NAND, AND, NOR or OR configuration, in which the ANY element acts as a pull-up and the ALL element acts as a pull-down, or vice-versa.
