Line 4:

The term commonly refers to devices such as [[read-only memory|ROM]]s, [[programmable array logic|PAL]]s, [[programmable logic array|PLA]]s and [[generic array logic|GAL]]s.

== Basic Descriptiondescription ==

Simple programmable logic devices (SPLD) are the simplest, smallest and least-expensive forms of programmable logic devices. SPLDs can be used in boards to replace standard logic components (AND, OR, and NOT gates), such as 7400-series TTL.

Line 37:

Memory cells control and define the function that the logic performs and how the various logic functions are interconnected.

== Fixed vs. Programmableprogrammable ==

Logic devices can be classified into two broad categories - fixed and programmable.
