VLSI. An IC that in complexity contains over 1000 gates or their equivalent.
A level of technological sophistication in the manufacturing of semiconductor chips that allows the equivalent of more than 100,000--and up to 1 million--transistors to be placed on one chip.
Refers to the number of logic gates in a device. By one convention, very-large-scale integration represents a device containing 1,000 to 999,999 gates.
