Customization : Is done by programming (by blowing internal fuses to achieve desired function) Reduction of component count & space : Is achieved by using an array of AND and OR (or NOR and NAND). Types of PLD : • PROM (Programmable Read-Only Memory) • PLA (Programmable Logic Array) • PAL (Programmable Array Logic) • GAL (Generic Array Logic) 3 Memory Array (programmable) 2 n words by m bits (OR array) Decoder (AND array) 1 2 3 4 ....
