可程序逻辑数组（Programmable Logic Array）（PLA）是一种可以实作组合逻辑电路的可程序逻辑设备。PLA有一组可编程的AND闸，其连接到一组可编程的OR闸，如此可以达到：「只在合乎设置条件时才允许产生逻辑信号输出。」PLA有2^N个AND闸来输入N个变量，并且需要M个OR闸来输出M个结果。PLA如此的逻辑门布局能用来规划大量的逻辑函式，这些逻辑函式必须先以积项（有时是多个积项）的原始形式进行齐一化。

PLA与可程序数组逻辑设备（PAL）的差别为PLA的AND闸、OR闸皆可编程。

A programmable logic array (PLA) is a kind of programmable logic device used to implement combinational logic circuits. The PLA has a set of programmable AND gate planes, which link to a set of programmable OR gate planes, which can then be conditionally complemented to produce an output. It has 2^N AND Gates for N input variables and for M outputs from PLA, there should be M OR Gates, each with programmable inputs from all of the AND gates. This layout allows for a large number of logic functions to be synthesized in the sum of products (and sometimes product of sums) canonical forms.
