Q. Explain about Integration Levels?
Initially only few gates were integrated consistently on a chip. This initial integration was termed as small-scale integration (SSI). With the advances in microelectronics technologies SSI gave way to Medium Scale Integration where hundreds of gates were constructed on a chip. Later phase was Large Scale Integration (1,000 gates) and extremely large integration (VLSI 1000,000 gates on a single chip). Currently we are in the era of Ultra Large Scale Integration (ULSI) where approximately 100,000,000 or even more components can be fabricated on a single chip.
