Large scale integration

nounStandard termElectronics

A historic classification for microchips containing thousands of logic gates.

Large scale integration (LSI) describes the density of early microprocessors and complex digital circuits that packed tens of thousands of transistors onto a single silicon chip. It marks the transition from simple logic blocks to complete systems like early calculators and computer processors. The term is mostly historic, having been superseded by very large scale integration (VLSI) as transistor counts climbed into the millions.

Heard on the job

We studied large scale integration by looking at the architecture of the 8086 processor.
