Very large scale integrated (VLSI) circuits that can be electrically programmed to implement complex digital logic. By combining many of the advantages of custom chips with the programmability of microprocessors, they are useful in a wide range of electronics applications. The name derives from their structure—a grid of programmable logic elements (gate array) and interconnection wires that can be configured at an engineer's workbench, or even inside a consumer electronic device (programmed in the field), as opposed to other technologies that must be preconfigured during chip fabrication.
