A programmable device (PROM) is
(a) programmable OR and fixed AND array
(b) programmable AND and fixed OR array
(c) programmable AND and programmable OR array
Programmable Array Logic
Programmable Logic Array
Number of Minterms
All minterms are created.
According to function OR is programmed
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
