Abstract
This specification describes means that permit the variation of circuits, particularly latch circuits, used in programmable logic array chips (PLAs). The latch circuits are changeable to enable the selection of one of three different latch configurations to be used or in combination on the same PLA chip. The differences in the circuit configurations of the different types of latches occur only in metallization pattern of the chip so that chips with different latch configurations can be manufactured with a minimum of different processing steps.
