A Programmable Logic Array (PLA) consists of an array of AND gates and an array of OR gates.
• The inputs connect to the AND gates.
• The output of the AND gates connect to the inputs of the OR gates.
Each input to the AND gates goes through a “fuse” that can be permanently broken or blown.
• If the fuse is broken, that input value does not go to that AND gate.
• The OR gate inputs also go through a set of fuses.
Hence they are known as Fused programmable AND array and Fused programmable OR array .
Option C is the Correct Answer.
