subject: E-basics: Moore's Law Knowledge Large Search - Moore's Law, Integrated Circuits - [print this page] co-founder Gordon Moore (GordonMoore) initiative. Which reads: IC On the capacity of Transistor Number, about every 18 months will be doubled, the performance will be almost double the price in half; or that each dollar can buy computer performance, will quadruple every 18 months. The Law reveals the speed of advances in information technology.
1965 4 19 Day "Electronics" magazine published an article on page 114 Fairchild engineers written by Moore entitled "Let IC Fill more of the components "of the article, the paper predicted Semiconductor Chip On the number of integrated transistors and resistors to double each year.
1975, the IEEE Moore in an academic paper presented at the annual meeting, according to the actual situation at the time of the Moore's Law was amended to "double every year" to "double every two years," , while the prevailing view now is "double every 18 months." But in September 1997 to accept an interview with Moore in a statement that he never said "double every 18 months."
California Institute of Technology professor CarverMead also involved in the proposal of Moore's Law. Moore said the past 20 years, his people called him the founder of Moore's Law approach not deserve. Intel has concluded that former officials DavidHouse the number of transistors doubled every 18 months. In fact, the chip's performance doubling every 18 months time. Molar stressed that he never said 18 months.
Moore's Law is not suitable for the capacity of the hard drive or other device on. Moore joked: "Moore's Law has been applied to any increase exponentially above things, I am glad to be well received."
Select the reason Silicon This is a miracle of materials science. Silicon is a good semiconductor (which it can conduct electricity, but also can control the manner of), although shrinkage of silicon crystal structure remains intact.
Moore's Law is broken?
Although many analysts and corporate officials have boasted on Moore's Law will be out of date, but it may still play a role.
Some people, such as Hewlett-Packard Labs StanWilliams and PhilKuekes that, by 2010 to shrink transistors will become a problem. Therefore, manufacturers need to find new alternatives, such as HP's "crossbar switching" (crossbarswitches).
Others, such as Intel's director of technology strategy PaoloGargini claimed that by 2015, manufacturers began to turn mixed chips (hybridchips), which combine elements of traditional transistors and emerging materials, such as silicon nanowires . By 2020, the new chip will be fully operational.
From a theoretical point of view, silicon transistors could continue to shrink, until the 4-nanometer production process in the event that, nano is a measure of size on a chip. A nanometer is one billionth of a meter. Current chips use 90-nanometer process. Time may be expected in about 2023. At that point, the current in transistor gate (transistorgate) and the gate oxide (gateoxide) distance will be very close, so will the electron drift (electronsdrift). If this happens, transistors will lose their reliability, because the transistors will be impossible to control the flow of electrons, hence the creation of 1s and 0s.
If the alternative transistor materials will never be found, Moore's Law will be invalid.
