1.	If a PAL has been programmed once ____________(a) Its logic capacity is lost(b) Its outputs are only active HIGH(c) Its outputs are only active LOW(d) It cannot be reprogrammedI had been asked this question in my homework.This intriguing question comes from Programmable Array Logic topic in portion Memory Devices of Digital Circuits
Answer» Right answer is (d) It cannot be REPROGRAMMED Explanation: PAL only has a PROGRAMMABLE AND plane and a fixed OR plane. SINCE, PAL is dynamic in nature. So, it can’t be reprogrammed.
