For Reprogrammability Plds Use?

Explanation: For reprogrammability, PLDs use EPROM (i.e. Erasable PROM). It erases the previous program and starts uploading a new one. However, data is erased by exposing it to UV-light, which is a tedious and time-consuming process.

Which PLD has arrays programmable?

PLA is a programmable logic device that has both Programmable AND array & Programmable OR array. Hence, it is the most flexible PLD. The block diagram of PLA is shown in the following figure.

What is a PLD used for?

A programmable logic device (PLD) is an electronic component used to build reconfigurable digital circuits. Unlike integrated circuits (IC) which consist of logic gates and have a fixed function, a PLD has an undefined function at the time of manufacture.
