摩尔定律 Moore's law

(重定向自Moore’s Law)
图中电脑处理器中晶体管数目的指数增长曲线符合摩尔定律
La ley de Moore comparada con los datos históricos (gráfico en idioma portugués).
Gordon Moore in 2004.

摩尔定律是由英特尔创始人之一戈登·摩尔提出来的。其内容为:集成电路上可容纳的电晶体(晶体管)数目,约每隔24个月便会增加一倍;经常被引用的“18个月”,是由英特尔首席执行官大卫·豪斯所说:预计18个月会将芯片的性能提高一倍(即更多的晶体管使其更快)。

半导体行业大致按照摩尔定律发展了半个多世纪,对二十世纪后半叶的世界经济增长做出了贡献,并驱动了一系列科技创新,社会改革,生产效率的提高和经济增长。个人电脑,因特网,智能手机等技术改善和创新都离不开摩尔定律的延续。

尽管这种趋势已经持续了超过半个世纪,摩尔定律仍应该被认为是观测或推测,而不是一个物理或自然法。预计摩尔定律将持续到至少2015年或2020年。然而,2010年国际半导体技术发展路线图的更添加长已经在2013年年底放缓;之后的时间里,晶体管数量密度预计只会每三年翻一倍。

Moore's law 摩尔定律

(重定向自Moore’s Law)
A plot of CPU transistor counts against dates of introduction; note the logarithmic vertical scale; the line corresponds to exponential growth with transistor count doubling every two years.
Gordon Moore in 2004.
An Osborne Executive portable computer, from 1982, with a Zilog Z80 4 MHz CPU, and a 2007 Apple iPhone with a 412 MHz ARM11 CPU; the Executive weighs 100 times as much, has nearly 500 times the volume, costs approximately 10 times as much (adjusted for inflation), and has about 1/100th the clock frequency of the smartphone.
An atomistic simulation for electron density as gate voltage (Vg) varies and Id-Vg in a nanowire MOSFET. The threshold voltage is around 0.45 V. Nanowire MOSFETs lie toward the end of the ITRS road map for scaling devices below 10 nm gate lengths. FinFET has three sides of the channel covered by gate, while some nanowire transistors have gate-all-around structure, enforcing better gate control [64]

Moore's law (/mɔərz.ˈlɔː/) is the observation that the number of transistors in a dense integrated circuit doubles approximately every two years. The observation is named after Gordon E. Moore, the co-founder of Intel and Fairchild Semiconductor, whose 1965 paper described 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.
