Difficulty: Easy
Correct Answer: reprogrammable and a CMOS device
Explanation:
Introduction / Context:
Generic Array Logic devices were introduced to improve upon PALs by enabling reprogrammability. GALs became staples in digital design for glue logic, address decoding, and small state machines, particularly before CPLDs and FPGAs became ubiquitous.
Given Data / Assumptions:
Concept / Approach:
Unlike earlier one-time programmable PALs that required windowed UV erasure or were blown fuses, GALs can be erased and reprogrammed electrically many times. Their CMOS implementation brings lower standby power and better noise margins compared with older bipolar families.
Step-by-Step Reasoning:
Verification / Alternative check:
Look at datasheets for GAL16V8 or GAL22V10 devices. They explicitly mention CMOS technology and electrically erasable programmability, enabling many design cycles with a single chip during prototyping.

Final Answer:
reprogrammable and a CMOS device
