Gordon Moore's original graph from 1965
Growth of transistor counts for Intel processors (dots) and Moore's Law (upper line=18 months; lower line=24 months)

## Earliest forms

The term Moore's Law was coined by Carver Mead around 1970.[4] Moore's original statement can be found in his publication "Cramming more components onto integrated circuits", Electronics Magazine 19 April 1965: Professor Carver Andress Mead (born 1 May 1934, in Bakersfield, California) is a prominent U.S. computer scientist. ... An integrated circuit (IC) is a thin chip consisting of at least two interconnected semiconductor devices, mainly transistors, as well as passive components like resistors. ...

 “ The complexity for minimum component costs has increased at a rate of roughly a factor of two per year ... Certainly over the short term this rate can be expected to continue, if not to increase. Over the longer term, the rate of increase is a bit more uncertain, although there is no reason to believe it will not remain nearly constant for at least 10 years. That means by 1975, the number of components per integrated circuit for minimum cost will be 65,000. I believe that such a large circuit can be built on a single wafer.[1] ”

Under the assumption that chip "complexity" is proportional to the number of transistors, regardless of what they do, the law has largely held the test of time to date. However, one could argue that the per-transistor complexity is less in large RAM cache arrays than in execution units. From this perspective, the validity of one formulation of Moore's Law may be more questionable. For other uses, see Transistor (disambiguation). ...

Gordon Moore's observation was not named a "law" by Moore himself, but by the Caltech professor, VLSI pioneer, and entrepreneur Carver Mead.[2] Moore, indicating that it cannot be sustained indefinitely, has since observed "It can't continue forever. The nature of exponentials is that you push them out and eventually disaster happens."[5] California Institute of Technology The California Institute of Technology (commonly known as Caltech) is a private, coeducational university located in Pasadena, California, in the United States. ...

Moore may have heard Douglas Engelbart, a co-inventor of today's mechanical computer mouse, discuss the projected downscaling of integrated circuit size in a 1960 lecture.[6] In 1975, Moore projected a doubling only every two years. He is adamant that he himself never said "every 18 months", but that is how it has been quoted. The SEMATECH roadmap follows a 24 month cycle. Dr. Douglas C.

## Understanding Moore's Law

Moore's law is not about just the density of transistors that can be achieved, but about the density of transistors at which the cost per transistor is the lowest[1]. As more transistors are made on a chip the cost to make each transistor reduces but the chance that the chip will not work due to a defect rises. If the rising cost of discarded non working chips is balanced against the reducing cost per transistor of larger chips, then as Moore observed in 1965 there is a number of transistors or complexity at which "a minimum cost" is achieved. He further observed that as transistors were made smaller through advances in photolithography this number would increase "a rate of roughly a factor of two per year".[1] Photolithography is a process used in semiconductor device fabrication to transfer a pattern from a photomask (also called reticle) to the surface of a substrate. ...

## Formulations of Moore's Law

PC hard disk capacity (in GB). The plot is logarithmic, so the fit line corresponds to exponential growth.

The most popular formulation is of the doubling of the number of transistors on integrated circuits every 18 months. At the end of the 1970s, Moore's Law became known as the limit for the number of transistors on the most complex chips. However, it is also common to cite Moore's Law to refer to the rapidly continuing advance in computing power per unit cost, because increase in transistor count is also a rough measure of computer processing power. On this basis, the power of computers per unit cost - or more colloquially, "bangs per buck" - doubles every 24 months (or, equivalently, increases 32-fold in 10 years).

A similar law (sometimes called Kryder's Law) has held for hard disk storage cost per unit of information.[9] The rate of progression in disk storage over the past decades has actually sped up more than once, corresponding to the utilization of error correcting codes, the magnetoresistive effect and the giant magnetoresistive effect. The current rate of increase in hard drive capacity is roughly similar to the rate of increase in transistor count. Recent trends show that this rate has been maintained into 2007.

According to Gerry/Gerald Butters,[10][11][12] the former head of Lucent's Optical Networking Group at Bell Labs, there is another version, called Butter's Law of Photonics,[13] a formulation which deliberately parallels Moore's law. Butter's Law [14] says that the amount of data coming out of an optical fiber is doubling every nine months. Thus, the cost of transmitting a bit over an optical network decreases by half every nine months. The availability of wavelength-division multiplexing (sometimes called "WDM") increased the capacity that could be placed on a single fiber by as much as a factor of 100. Optical networking and DWDM is rapidly bringing down the cost of networking, further progress seems assured. As a result, the wholesale price of data traffic collapsed in the dot-com bubble. Dark fiber overcapacity and the optical network bandwidth oversupply greatly exceeding demand of even the most optimistic forecasts by a factor of up to 30 in many areas. Bell Laboratories (also known as Bell Labs and formerly known as AT&T Bell Laboratories and Bell Telephone Laboratories) was the main research and development arm of the United States Bell System. ...

Due to the mathematical power of exponential growth (similar to the financial power of compound interest), seemingly minor fluctuations in the relative growth rates of CPU performance, RAM capacity, and disk space per dollar have caused the relative costs of these three fundamental computing resources to shift markedly over the years, which in turn has caused significant changes in programming styles. For many programming problems, the developer has to decide on numerous time-space tradeoffs, and throughout the history of computing these choices have been strongly influenced by the shifting relative costs of CPU cycles versus storage space.

## An industry driver

Although Moore's Law was initially made in the form of an observation and forecast, the more widely it became accepted, the more it served as a goal for an entire industry. This drove both marketing and engineering departments of semiconductor manufacturers to focus enormous energy aiming for the specified increase in processing power that it was presumed one or more of their competitors would soon actually attain. In this regard, it can be viewed as a self-fulfilling prophecy. Observation is an activity of a sapient or sentient living being (e. ...

The implications of Moore's Law for computer component suppliers are very significant. A typical major design project (such as an all-new CPU or hard drive) takes between two and five years to reach production-ready status. In consequence, component manufacturers face enormous timescale pressures—just a few weeks of delay in a major project can spell the difference between great success and massive losses, even bankruptcy. Expressed as "a doubling every 18 months", Moore's Law would suggests phenomenal progress for technology over the span of a few years. Expressed on a shorter timescale, however, this would equate to an average performance improvement in the industry as a whole of close to 1% per week. Thus, for a manufacturer in the competitive CPU market, a new product that is expected to take three years to develop and turns out just three or four months late is 10 to 15% slower, bulkier, or lower in capacity than the directly competing products, and is close to unsellable. If instead we accept that performance will double every 24 months, rather than every 18 months, a 3 to 4 month delay would translate to 8-11% lower performance. The NASA Columbia Supercomputer. ...

## Future trends

As of Q1 2007, most PC processors were being fabricated on a 65nm process, with some 90 nm chips still left in retail channels, mostly from AMD, as they were slightly behind Intel in transitioning away from 90 nm. On January 27, 2007, Intel demonstrated a working 45nm chip codenamed "Penryn", intending mass production to begin in late 2007.[15] A decade ago, chips were built using a 500 nm process. (The diameter of an atom is on the order of 0.1 nm.) Companies are working on using nanotechnology to solve the complex engineering problems involved in producing chips at the 32 nm and smaller levels—a process that may once again postpone the industry's meeting the limits of Moore's Law.

Less recent computer industry technology "roadmaps" predict (as of 2001) that Moore's Law will continue for several chip generations. Depending on the doubling time used in the calculations, this could mean up to a hundredfold increase in transistor count per chip within a decade. The semiconductor industry technology roadmap uses a three-year doubling time for microprocessors, leading to a tenfold increase in the next decade. 2001 is a common year starting on Monday of the Gregorian calendar, and also: The International Year of the Volunteer The United Nations Year of Dialogue Among Civilizations Events January January 1 - A black monolith measuring approximately nine feet tall appears in Seattles Magnuson Park, placed by an anonymous...

Since such rapid exponential improvement would, within a generation or two, allow to put 100 GHz personal computers in every home and 20 GHz devices in every pocket, some commentators have speculated that sooner or later computers will meet or exceed any conceivable need for computation. This is only true for some problems—there are others where exponential increases in processing power are matched or exceeded by exponential increases in complexity as the problem size increases.

Extrapolation partly based on Moore's Law has led futurists such as Vernor Vinge, Bruce Sterling, and Ray Kurzweil to speculate about a technological singularity. However, on April 13, 2005, Gordon Moore himself stated in an interview that the law may not hold for too long, since transistors would eventually reach the limits of miniaturization at atomic levels: In mathematics, extrapolation is the process of constructing new data points outside a discrete set of known data points. ...

 “ In terms of size [of transistor] you can see that we're approaching the size of atoms which is a fundamental barrier, but it'll be two or three generations before we get that far—but that's as far out as we've ever been able to see. We have another 10 to 20 years before we reach a fundamental limit. By then they'll be able to make bigger chips and have transistor budgets in the billions.[16] ”

While this time horizon for Moore's Law scaling is possible, it does not come without underlying engineering challenges. One of the major challenges in integrated circuits that use nanoscale transistors is increase in parameter variation and leakage currents. As a result of variation and leakage, the design margins available to do predictive design are becoming harder. Such systems also dissipate considerable power even when not switching. Adaptive and statistical design along with leakage power reduction is critical to sustain scaling of CMOS. A good treatment of these topics is covered in Leakage in Nanometer CMOS Technologies.

Kurzweil expansion of Moore's Law from integrated circuits to earlier transistors, vacuum tubes, relays and electromechanical computers.

 “ Moore's Law of Integrated Circuits was not the first, but the fifth paradigm to forecast accelerating price-performance ratios. Computing devices have been consistently multiplying in power (per unit of time) from the mechanical calculating devices used in the 1890 U.S. Census, to [Newman's] relay-based "Robinson" machine that cracked the [German Lorenz cipher], to the CBS vacuum tube computer that predicted the election of Eisenhower, to the transistor-based machines used in the first space launches, to the integrated-circuit-based personal computer.[17] ”

Thus, Kurzweil conjectures that it is likely that some new type of technology will replace current integrated-circuit technology, and that Moore's Law will hold true long after 2020. He believes that the exponential growth of Moore's Law will continue beyond the use of integrated circuits into technologies that will lead to the technological singularity. The Law of Accelerating Returns described by Ray Kurzweil has in many ways altered the public's perception of Moore's Law. It is a common (but mistaken) belief that Moore's Law makes predictions regarding all forms of technology, when it actually only concerns semiconductor circuits. Many futurists still use the term "Moore's Law" in this broader sense to describe ideas like those put forth by Kurzweil. For other uses, see Paradigm (disambiguation). ...

Then again, the law has often met obstacles that appeared insurmountable, before soon surmounting them. In that sense, Moore says he now sees his law as more beautiful than he had realised: "Moore's Law is a violation of Murphy's Law.

## Other considerations

Not all aspects of computing technology develop in capacities and speed according to Moore's Law. Random Access Memory (RAM) speeds and hard drive seek times improve at best a few percentage points each year. Since the capacity of RAM and hard drives is increasing much faster than is their access speed, intelligent use of their capacity becomes more and more important. It now makes sense in many cases to trade space for time, such as by precomputing indexes and storing them in ways that facilitate rapid access, at the cost of using more disk and memory space: space is getting cheaper relative to time. A processors core Computing is a very broad topic that has become pandemic to modern uses of technology. ... Random access memory (usually known by its acronym, RAM) is a type of data storage used in computers. ... Typical hard drives of the mid-1990s. ...

Another sometimes misunderstood point is that exponentially improved hardware does not necessarily imply exponentially improved software performance to go with it. The productivity of software developers most assuredly does not increase exponentially with the improvement in hardware, but by most measures has increased only slowly and fitfully over the decades. Software tends to get larger and more complicated over time, and Wirth's law even states humorously that "Software gets slower faster than hardware gets faster". For other uses, see Hardware (disambiguation). ... Computer software (or simply software) refers to one or more computer programs and data held in the storage of a computer for some purpose. ... Wirths law in computing was made popular by Niklaus Wirth in 1995. ...

Moreover, there is a popular misconception that the clock speed of a processor determines its speed, also known as the Megahertz Myth. This actually also depends on the number of instructions per tick which can be executed (as well as the complexity of each instruction, see MIPS, RISC and CISC), and so the clock speed can only be used for comparison between two identical circuits. Of course, other factors must be taken into consideration such as the bus width and speed of the peripherals. Therefore, most popular evaluations of "computer speed" are inherently biased, without an understanding of the underlying technology. This was especially true during the Pentium era when popular manufacturers played with public perceptions of speed, focusing on advertising the clock rate of new products.[19] This is a list of uncontroversial, undisputed clarifications to common misconceptions. ...

As the cost of computer power to the consumer falls, the cost for producers to achieve Moore's Law has the opposite trend: R&D, manufacturing, and test costs have increased steadily with each new generation of chips. As the cost of semiconductor equipment is expected to continue increasing, manufacturers must sell larger and larger quantities of chips to remain profitable. (The cost to tape-out a chip at 180 nm was roughly US\$300,000. The cost to tape-out a chip at 90 nm exceeds US\$750,000, and is expected to exceed US\$1,000,000 for 65 nm.) In recent years, analysts have observed a decline in the number of "design starts" at advanced process nodes (130 nm and below for 2007). While these observations were made in the period after the 2000 economic downturn, the decline may be evidence that traditional manufacturers in the long-term global market cannot economically sustain Moore's Law. However, Intel was reported in 2005 as stating that the downsizing of silicon chips with good economics can continue during the next decade.[20] Intel's prediction of increasing use of materials other than silicon was verified in mid-2006, as was its intent of using trigate transistors from around 2009 [citation needed]. Researchers from IBM and Georgia Tech created a new speed record when they ran a silicon/germanium helium supercooled transistor at 500 gigahertz (GHz).[21] The transistor operated above 500 GHz at 4.5 K (—451°F)[22] and simulations showed that it could likely run at 1 THz (1,000 GHz), although this was only a single transistor, and practical desktop CPUs running at this speed are extremely unlikely using contemporary silicon chip techniques [citation needed].

 moores law comments (641 words) Moore predicted: "Integrated circuits will lead to such wonders as home computers - or at least terminals connected to a central computer, automatic controls for automobiles, and personal portable communications equipment." This is a remarkable prediction given that it was made in 1965. Thus, Moore's Law was the driver of a positive feedback loop that made Gordon Moore's 1965 predictions come true: the integrated circuit is playing a central role in every facet of modern life. Moore's Law was not only a prediction - it also formed a blueprint for the development of the semiconductor industry.
 Moore's Law - Wikipedia, the free encyclopedia (2478 words) If Moore's Law were applicable to the airline industry, a flight from New York to Paris in 1978 that cost \$900 and took seven hours, would now cost about \$0.01 and take less than one second. Although Moore's Law was initially made in the form of an observation and forecast, the more widely it became accepted, the more it served as a goal for an entire industry. "Moore's Law is a violation of Murphy's Law.
