A type of programmable logic device (PLD) — an integrated circuit that can be customized after assembly. Specifically, an FPGA is a programmable type of gate array, which is an integrated circuit that contains a configuration of uncommitted elements in a prefabricated base wafer. See PLD.

A programmable logic device which is more versatile than traditional programmable devices such as PALs and PLAs, but less versatile than an application-specific integrated circuit. Some field-programmable gate arrays use fuses such as those found in programmable logic devices, but others are based on SRAM equivalents.

ield rogrammable ate rray. FPGAs are a class of programmable logic devices. They feature a gate-array-like architecture with a matrix of logic cells surrounded by a periphery of I/O cells.
