How did very large-scale integration increase the power of computer chips?

Very large-scale integration (VLSI) increased the power of computer chips by dramatically increasing their circuit density. While early integrated circuits contained only a small number of components, VLSI allowed engineers to pack thousands—and eventually billions—of electronic components, such as transistors, onto a single silicon chip of the same physical size.123

This increase in power was driven by the steadily shrinking size of individual transistors. By reducing the dimensions of these components, manufacturers could fit significantly more processing power and memory capacity into the same footprint. This technological progression, often associated with Moore’s law, enabled the development of high-performance microprocessors capable of operating at gigahertz frequencies.452

Ultimately, these advancements made it possible to transition from large, room-sized computers to compact, powerful microcomputers and personal devices, fundamentally transforming modern electronics by making high-level computing power both affordable and portable.125
