Abstract:
A programmable array logic cell 60 including a sum-of-products array having a single OR gate 70 for providing a sum signal, and including an XOR gate 80 for combining the sum signal with a product signal provided by an AND gate 78 from selected array input and/or feedback signals. The product signal can be the previous state output signal Q for a JK flip flop configuration, or a forced high or low signal for other configurations for programmable output signal polarity.
