Define Programmable Logic array & Programmable Array Logic?

Combinational ckt is implemented with ROM Do not care conditions become an address input. PLA is alike to ROM. PLA doesn't provide full decoding of all available variables and Decoder is replaced with group of AND gates.

Instance:

F0 = A + B' C'
F1 = A C' + A B
F2 = B' C' + A B
F3 = B' C + A
