ABSTRACT:
A programmable logic array (PLA) circuit includes a product term array and a sum term array. The product term array is coupled to the sum term array via a control transistor. A gate electrode of the control transistor is coupled to an output of the product term array, and a source (or drain) electrode is coupled to an input end of the sum term array. A drain (or source) electrode of the control transistor is coupled to a power source. N-channel type transistors are employed in the product term and the sum term arrays, while a P-channel type transistor is employed as the control transistor.
