Evolution of VLSI

The journey of Very Large-Scale Integration technology has been a remarkable one, marked by continuous innovation and transformative leaps..

It all started in the 1960s with Small Scale Integration (SSI), where a few electronic components were packed onto a chip.

The 1970s introduced Medium Scale Integration (MSI), enabling hundreds of components.

The real breakthrough came in the 1980s with VLSI, as microchips accommodated thousands to millions of components, boosting processing power.

Through the 1990s and 2000s, VLSI kept pushing boundaries, bringing forth Moore’s Law – the doubling of transistors on a chip every two years. Nanometer-scale manufacturing emerged, leading to even more powerful chips.

‘Moore’s Law, named after Intel co-founder Gordon Moore, is a fundamental principle that has been driving the rapid advancement of technology for decades. Formulated in 1965, Moore’s Law predicts that the number of transistors on a microchip would double approximately every two years, leading to increased computing power and efficiency.”

Today, Very Large-Scale Integration enables multi-core processors, 3D stacking, and specialized architectures for AI and IoT.The evolution of Very Large-Scale Integration has led to sleeker devices, supercomputers, and IoT wonders, shaping the modern world’s technological landscape.
