Moore's Law

• Print

Moore’s Law, first stated in about 1965, stated that the number of transistors on an mass market silicon chip doubles every two years or so. The number of transistors on a chip is a measure of its storage capacity or processing power. The Law was first put forward by Graham Moore, a co founder of Intel.

The limitation which exists is that there is a lower limit to the size of transistor, namely the size of an atom. This limit may in fact be irrelevant if light or quantum computers have become a reality. Many light photons and quantum bits which serve as the storage units can fit inside the same space.
