Abstract

This programmable logic array masterslice includes a contiguous array of independent AND/OR segments with each row of a segment being either an independent product term or a portion of an extended product term. A row of several AND/OR segments connected together forms an extended product term. The technique of enabling each physical array term to contain a single extended product term or several independent product terms allows more effective utilization of array bits and, hence, chip or wafer area.
