gate array: meaning, definition, pronunciation and examples

No. An FPGA (Field-Programmable Gate Array) can be reprogrammed by the user after manufacture. A traditional gate array is customised only once during the manufacturing process (mask-programmed) and cannot be changed afterwards.

Gate arrays offer a balance. For a specific, complex logic function not available as a standard chip, a gate array is cheaper and faster to develop than a fully custom ASIC, while providing better performance and lower unit cost than a programmable device for medium production volumes.

Their use has declined significantly with the advancement of FPGAs and complex standard-cell ASICs. However, the concept remains historically important and they may still be used in some legacy systems or very specific, cost-sensitive applications.

It means the customisation of the gate array's function is done by designing the final metal interconnection layers (using photomasks) during chip fabrication. This is a factory process, not something the end-user does.

An integrated circuit (IC) consisting of a predefined, patterned arrangement of transistors (logic gates) that can be customised later in the manufacturing process to perform a specific function.

Gate array is usually technical in register.
