ABSTRACT:
A mask programmable logic array (PLA) for producing a particular digital output given a certain digital input. The input signals to the PLA first pass through a series of AND gates resulting in a predetermined number of product terms being formed. The product signals then pass through a set of OR gates to become the final output signals. In the subject invention, the AND gates and OR gates are implemented through the use of NOR-NOR logic. A first set of NOR gates is implemented in an array to receive input signals and to produce product terms. A second and third set of NOR gates form two arrays. These two arrays are then located on either side of the first array to receive selected product signals in order to produce final output signals. In effect the OR portion of the PLA has been split into two arrays.
