A semicustom IC consisting of a regular arrangement of gates that are interconnected through one or more layers of metal to provide custom functions. Generally, gate arrays are preprocessed up to the first interconnect level so they can be quickly processed with final metal to meet a customer's specified function.
A circuit consisting of an array of logic gates aligned on a substrate in a regular pattern.
An array formed from elementary gates, usually 2-input NOR or 2-input NAND (CMOS) gates. A gate array is configured into a variety of logical circuits through customized interconnect. A gate array is often defined as a semicustom digital integrated circuit.
