{{merge|UncommmittedUncommitted Logic Array}}

A '''gate array''' or '''uncommitted logic array''' (ULA) is an approach to the design and manufacture of [[application-specific integrated circuit]]s (ASICS). A gate array circuit is a prefabricated circuit with no particular function in which [[transistor]]s, standard [[logic gate]]s, and other [[active device]]s are placed at regular predefined positions and manufactured on a [[wafer (electronics)|wafer]], usually called '''master slice'''. Creation of a circuit with a specified function is accomplished by adding metal interconnects to the chips on the master slice late in the manufacturing process, allowing the function of the chip to be customised as desired.
