VLSI, or Very Large Scale Integration, is a technology used to create integrated circuits by combining thousands or even millions of transistors onto a single chip. This process allows for the miniaturization of electronic components, making devices smaller, faster, and more efficient. VLSI is essential in modern electronics, powering everything from smartphones to computers. The development of VLSI has revolutionized the electronics industry, enabling complex functionalities in compact forms. It plays a crucial role in various applications, including microprocessors, memory chips, and digital signal processors. As technology advances, VLSI continues to evolve, supporting innovations in fields like artificial intelligence and internet of things.
