Moore''s law is the observation that the number of transistors on an integrated circuits will double approximately every two years. It is very important to note that this law is an observation and not an actual physical or natural law.

As of 2010 the update to the International Technology Roadmap for Semiconductors has shown growth slowing by 2013 after which densities are going to double only every three years. We are hitting the limits of the number of electrons that can be fit in a given area.

The age of Moorepocalypse may still be few years away, but there are signs that it is already here. Just ask the second largest chip manufacturer AMD. AMD’s Chief Product Architect John Gustafson believes the company’s difficulty in transitioning from a 28 nanometer chip to a 20 nanometer chip shows that we’ve already reached the beginning of the end. The end of Moore’s Law for single core CPU led to Intel and AMD to resort to a multi-core processor to keep up with the ever growing demands of consumers.

Chief Technology officer of Broadcom Henry Samueli told several Silicon Valley veterans that “Moore’s Law was coming to an end—in the next decade it will pretty much come to an end so we have 15 years or so”.

It should be noted that the predictions about end of Moore''s Law are almost as old as the observation itself posited by Gordon Moore in 1965. Theoretical physicist Michio Kaku believes Moore''s Law has about 10 years of life left before shrinking transistors smack up against the limitation of the law physics. In his 2011 book “Physics of the Future”, Kaku predicted that the end of Law will turn Silicon Valley into a rust belt if a suitable replacement for silicon was not found.
