Moore’s Law is an empirical observation that the number of transistors in an integrated circuit (IC) doubles approximately every two years. It is named after Gordon Moore, the co-founder of Fairchild Semiconductor and Intel. Moore’s Law is not a law of physics, but rather an observation and projection of a historical trend. The observation was first made in 1965, when Moore posited a doubling every year in the number of components per integrated circuit, and projected this rate of growth would continue for at least another decade. In 1975, looking forward to the next decade, he revised the forecast to doubling every two years, a compound annual growth rate (CAGR) of 41%. While Moore did not use empirical evidence in forecasting that the historical trend would continue, his prediction has held since 1975 and has since become known as a “law” .
Moore’s Law has been used in the semiconductor industry to guide long-term planning and to set targets for research and development, thus functioning to some extent as a self-fulfilling prophecy. Advancements in digital electronics, such as the reduction in quality-adjusted microprocessor prices, the increase in memory capacity (RAM and flash), the improvement of sensors, and even the number and size of pixels in digital cameras, are strongly linked to Moore’s Law . These ongoing changes in digital electronics have been a driving force of technological and social change, productivity, and economic growth.
However, industry experts have not reached a consensus on exactly when Moore’s Law will cease to apply. Microprocessor architects report that semiconductor advancement has slowed industry-wide since around 2010, slightly below the pace predicted by Moore’s law . The slowing of Moore’s Law has been attributed to several factors, including the increasing difficulty of manufacturing at smaller scales, the increasing cost of research and development, and the physical limitations of the materials used in semiconductor manufacturing .
In conclusion, Moore’s Law has been a driving force behind the rapid advancement of digital electronics and has played a significant role in shaping the modern world. While the pace of advancement may slow in the future, the impact of Moore’s Law on technology and society will continue to be felt for years to come..
