1 votes 1 votes PROM PAL PLA Definition Programmable ROM Programmable Array Logic Programmable Logic Array AND array Fixed Programmable Programmable OR array Programmable Fixed Programmable Number of Minterms All minterms are created. According to function OR is programmed Simple implementation Not flexible For each OR gate same minterm should be implemented separately Only needed minterms are created using AND array. One minterm can be shared among all OR gates. Negation of minterms are done in OR array using EXOR gates. So answer is A sh!va answered Mar 2, 2017 sh!va comment Share Follow See all 0 reply Please log in or register to add a comment.
