Definition - What does Gate Array mean?
A gate array is also known as an uncommitted logic array.
Techopedia explains Gate Array
In general, this type of chip is a prefabricated chip using NAND or other logical gates, often in a scenario where engineers might include different sets of transistors and resistors that, although built into the circuit board, are not connected for logical operation. One type of gate array called a field-programmable gate array offers clients the ability to do more engineering on their end of a project.
