Programmed logic array with external signals introduced between its AND plane and its OR plane

摘要

A combinational logic device, such as an AND gate, is connected to control the flow of information along a wordline from the AND plane to the OR plane of a PLA (programmed logic array). To each such combinational logic device is applied an input signal from a source external to the PLA, so that the PLA's output can respond relatively quickly to this input signal-that is, the PLA is capable of relatively quick decision making.
