An observation made by Intel co-founder Gordon Moore in 1965. He noticed that the number of transistors per square inch on integrated circuits had doubled every year since their invention. Moore’s law predicts that this trend[->0] will continue into the foreseeable future.
Although the pace has slowed, the number of transistors per square inch has since doubled approximately every 18 months. This is used as the current definition of Moore's law.
History
The term "Moore's law" was coined around 1970 by the Caltech[->1] professor, VLSI[->2] pioneer, and entrepreneur Carver Mead[->3] in reference to a statement by Gordon E. Moore[->4].[7]HYPERLINK \l "cite_note-SSCSnewsletterSept06-14"[14] Predictions of similar increases in computer power had existed years prior. Alan Turing[->5] in his 1950 paper Computing Machinery and Intelligence[->6] had predicted that by the turn of the millennium, we would have "computers with a storage capacity of about 10^9", what today we would call "128 megabytes." Moore may have heard Douglas Engelbart[->7], a co-inventor of today's mechanical computer mouse, discuss the projected downscaling of integrated circuit size in a 1960 lecture.[15] A New York Times[->8] article published August 31, 2009, credits Engelbart as having made the prediction in 1959.[16]
Moore's original statement that transistor counts had doubled every year can be found in his publication "Cramming more components onto integrated circuits[->9]", Electronics Magazine[->10] 19 April 1965:
As a target for industry and a self-fulfilling prophecy
Although Moore's law was initially made in the form of an observation[->11] and forecast[->12], the more widely it became accepted, the more it served as a goal for an entire industry. This drove both marketing[->13] and engineering[->14] departments of semiconductor[->15] manufacturers to focus enormous energy aiming for the specified increase in processing power that it was presumed one
