ABSTRACT:
A reduced power programmable logic array is disclosed. The circuit includes an AND array, coupled through product term lines to an output OR array. Pull-up devices in the OR array are gated to one of the active product term lines. Also disclosed is method for choosing a product term line for gating pull-up devices such that power consumption in the pull-up devices is minimized.
