This question originally asked, 'What is LS in (an) IC?' and it appeared to be an incomplete thought or including a partial detail. The term "LSI" came after "SSI" for Small Scale Integration, which refers to logic circuits containing as few as two transistors. Therefore Large Scale Integration (or LSI) must refer to an integrated circuit chip containing two or more logic circuits, but likely referring to a chip with tens of thousands of logic circuits.

Modern Integrated Circuits often have hundreds of thousands of transistors or even millions of them, so it is also likely the term "LSI" is only used when speaking in an academic or historical context.

The term Very Large Scale Integration or "VLSI" is commonly used after the 1980's.

A Google Scholar search for the term "VLSI" returns 452,000 articles excluding patents as of today.
