Which of the following consists of an array of gates which can be used to patch an error in a ROM or alter the meaning of instruction?
PLA consists of an array of gates which can be used to patch an error in a ROM or alter the meaning of instruction.
A programmable logic array (PLA) is a kind of programmable logic device used to implement combinational logic circuits. The PLA has a set of programmable AND gate planes, which link to a set of programmable OR gate planes, which can then be conditionally complemented to produce an output.
A ROM is a combinational component for storing data. The data might be a truth table or the data might be the control words for a micro programmed CPU.
