通用阵列逻辑（英语：Generic Array Logic, GAL）是Lattice半导体公司于1980年代中期，以可程序逻辑数组（PAL）为基础所强化修改成的一种可程序逻辑设备（PLD）。

就外型封装型态上与接脚数目上，GAL与可程序逻辑数组并没有太大的差别，甚至在芯片的编号规则上都有相同的命名脉络与规则可循，如16V8、22V10等，真正的差别在于芯片内部的表现特性，在程序刻录的特性上，GAL不像传统可程序逻辑数组只能刻录一次（One-Time Programmable，OTP），而是能多次刻录、多次清除芯片内的（数字逻辑）程序。

The Generic Array Logic (also known as GAL) device was an innovation of the PAL and was invented by Lattice Semiconductor. The GAL was an improvement on the PAL because one device was able to take the place of many PAL devices or could even have functionality not covered by the original range. Its primary benefit, however, was that it was eraseable and re-programmable making prototyping and design changes easier for engineers.
