There are, in fact, several Moore’s Laws. At the beginning, Gordon Moore, an engineer with Fairchild Semiconductor (a co-founder of Intel) showed in 1965 that the number of transistors per semi-conductor component would double every 18 months, at a constant price. But, very quickly, different Moore’s Laws would emerge to characterize the exponential growth in calculating power, density, complexity…

This animation represents the evolution over time of the number of transistors per component (microprocessor) The ordinate is graduated with a logarithmic scale. Thus, this truly shows an exponential growth rate.

We are currently in a slowdown phase where the criterion of density is concerned (thermal dissipation, quantum effects) and so the growth of this curve is slowing down.

**Moore’s Law**, illustrated here, rests on a single type of component: the **microprocessors **of the Intel family. The microprocessor is the most complex part of a computer. It contains the registries…
