Question

Why antifuses are implemented in a PLD?

(a) To protect from high voltage

(b) To increase the memory

(c) To implement the programmes

(d) As a switching devices

This question was posed to me at a job interview.

Origin of the question is Programmable Logic Array in chapter Memory Devices of Digital Circuits

Answer 1

Right choice is (c) To implement the programmes

Explanation: Programmable Logic Devices is a collection of a large number of gates, flip-flops, registers that are interconnected on the chip. Programming is accomplished by using antifuses in a PLD and it is fabricated at the cross points of the gates.
