ABSTRACT:
A logic array includes an AND plane, a first OR plane, and a second OR plane. The AND plane is adapted to receive a plurality of logic array inputs and provide a plurality of minterms. Each minterm represents a logical combination of a subset of the plurality of logic array inputs. The first OR plane is adapted to receive the minterms and provide a plurality of intermediate outputs. Each intermediate output represents a logical combination of a subset of the minterms. The second OR plane is adapted to receive the intermediate outputs and provide a plurality of logic array outputs. Each logic array output represents a logical combination of a subset of the intermediate outputs. A method for programming a logic array includes providing a plurality of minterms. A plurality of subsets of the minterms are logically combined to define a plurality of intermediate outputs. A plurality of subsets of the intermediate outputs are logically combined to define a plurality of logic array outputs.
