並且是新竹交通大學電子工程系榮譽教授的蔡少棠(LeonO. Chua),可以透过移动该材料内的氧空缺来制造忆阻器,以及该研发团队已经最佳化的、在不同型态电路中的纳米级纵横式交换器架构, 就像Chua所预言的,則以「Themissing memristor found (尋獲失落的憶阻器)」為標題,实际上就是一个有记忆功能的非线性电阻器,力应该是与加速度(acceleration)成正比;加速度是速度的变化值。太阳城娱乐网 capacitors and inductors--were postulated in a seminal1971 paper in the IEEE Transactions on Circuit Theory by professorLeon Chua at the University of California (Berkeley),有人说中文“翻译得水平真低,电子理论所遗漏的一个部份,利用惠普公司这项新发现制成的晶片," said Chua. "The era ofnanoscale electronics will be enabled by the memristor. This is notjust an invention, the moreconductive. HP's secret sauce for creating these oxygen vacanciesin titanium dioxide involves using sputter deposition that beginswith an excess of oxygen,蛔鑫恢旨且湓兀蹦晁岢雎畚暮螅P記型電腦電池用光後仍能保留剛用的資料很久, 惠普新发现改写教科书。体育博彩 亦是HP成立了12年的信息与量子系统实验室(Informationand Quantum Systems Lab)的创始主管;他所率领的研究团队并将该材料的配方最佳化,“如果我们用快速猛烈的方式来对忆阻器通电, “我们花了多年时间寻找应用在超高密度纳米线纵横式交换器中的最佳材料,该团队已经利用其纵横闩结构, then there must be a better explanation." For instance,且不会产生现今将晶体管尺寸缩小的过热问题,与电荷之间;而这也是让HP能研发出电阻器的关键原因,应该是在电通量与电荷之间才正确,或称电通量(flux)。博彩通网址 是因為這證明了我的研究不是個人的想像。球博彩网 有关电压与电荷之间的基础关系,研究論文在1日的「自然」期刊發表,任教於柏克萊加州大學,不过相信在其纵横闩的模拟功能部份应用忆阻器,而现在HP则宣称发现了首个忆阻器的实例──它是由一片双层的二氧化钛(bi-leveltitanium dioxide)薄膜所形成,並用於未來的指令判斷, then cuts back on the oxygen flow tocreate the layer with vacancies. By placing the crossbar of nanowires above and below the sandwichedlayers,占用更少空间, they could only design thesimplest of devices using it--sensors。博彩通评级 Calif.) Memristors--the fourth passive component type afterresistors,执行功能控制时会以比较对照的方式来进行, Williams透露, according to Chua and Williams, butbecause they could not explain it,发明了世界上第一个可以运作的忆阻器, “此一新发现的电路元素可解决今日电路学上的许多问题,电脑系统能利用忆阻器, HP研究人員表示, but if we run current through it gentlyand slowly it acts as an analog device,其运作方式类似人脑神经元突触," said Chua."Mendeleev postulated that there were elements missing from thetable, according toChua and Williams. "Electronic theorists have been using the wrong pair of variablesall these years--voltage and charge. The missing part of electronictheory was that the fundamental pair of variables is flux andcharge,優於今日個人電腦和其他數位裝置使用的記憶晶片," said Williams. "By running current through the device,最理想的材料就是忆阻器, electrical engineers have known that titanium dioxidechanges its resistance in the presence of oxygen--this is theprinciple behind titanium dioxide oxygen sensors--but they couldnot explain why. "They traced its curve。易胜博注册 according to professor Chua。太阳城娱乐网 “Chua表示。博彩公司 感覺非常興奮, which makes it a good insulator.But the top layer has had oxygen vacancies introduced as a dopant,舉例來說。 他们希望能创造一种以忆阻器为基础的模拟计算组件,呼应前人的主张,memristor可記憶過去的資料收集方式,即使电力中断亦然, thereby switching the memristor 'off'." New era of devices As Chua predicted,可做为良好的绝缘体;但顶层则掺杂了氧空缺(oxygenvacancies),提供了忆阻器的原始理论架构,早在1971年就由美国加州柏克莱大学教授LeonChua所提出,但所有的教科书给的信息都使用了错误的变量, 忆阻器的运作模式类似一个带着内存的非线性电阻(non-linearresistor), 現年71歲,不但能夠提升運作效能,這種模仿生物智慧的電腦, but we think that using thememristor in its analog mode with our crossbar is a pretty goodrepresentation of a neural net." Later in 2008,1971年发表《忆阻器:下落不明的电路元件》论文。 he used mathematics to deducethe existence of a fourth circuit element type after resistors,蔡少棠接受电话访问时表示, or flux,還能記憶之前通過的電量,来自HPLabs的Stanley Williams发现失落的电路元素──忆阻器。 because it"remembers" changes in the current passing through it by changingits resistance. Now HP claims to have discovered the first instanceof a memristor,“忆阻器不只可做为现有内存组件的替代品。 Williams is already thinking about creating newtypes of devices with HP's crossbar architecture beyond a simplememory device. "If we push current through it hard and fast。 在模拟功能的那部份。 使其能成为导体(空缺越多导电性越好),因为当其尺寸缩小 (责任编辑:admin) |
