Gate array
A gate array is an approach to the design and manufacture of application-specific integrated circuits (ASICs) using a prefabricated chip with components that are later interconnected into logic devices (e.g.

TYPE OF DIGITAL CIRCUIT
Programmable electrically erasable logic; Gate Array Logic; Generic array logic
<hardware, integrated circuit> (GAL) A newer kind of
Programmable Array Logic based on EEPROM storage cells,
been pioneered by Lattice. GALs can be erased and
reprogrammed and usually replace a whole set of different PALs
(hence the name).

TYPE OF DIGITAL CIRCUIT
Programmable electrically erasable logic; Gate Array Logic; Generic array logic
The Generic Array Logic (also known as GAL and sometimes as gate array logic) device was an innovation of the PAL and was invented by Lattice Semiconductor. The GAL was an improvement on the PAL because one device type was able to take the place of many PAL device types or could even have functionality not covered by the original range of PAL devices.

Gate array
A gate array is an approach to the design and manufacture of application-specific integrated circuits (ASICs) using a prefabricated chip with components that are later interconnected into logic devices (e.g. NAND gates, flip-flops, etc.) according to a custom order by adding metal interconnect layers in the factory. It was popular during upheaval in semiconductor industry in 80s and its usage declined by end of 90s.
Similar technologies have also been employed to design and manufacture analog, analog-digital, and structured arrays, but, in general, these are not called gate arrays.
Gate arrays have also been known as uncommitted logic arrays (ULAs), which also offered linear circuit functions, and semi-custom chips.
