A memristor, or memory resistor, is described as one of the basic elements (resistor, capacitor, inductor) of electronic circuits, because it can’t be replaced by any combination of these elements.This element can change its resistivity according to the voltage, but even after disconnection it remembers resistivity for unlimited time. It can work like analog memory or a resistive switch. Emerging technology provides a unique opportunity to introduce science within education. The development of Memristors, the fourth passive component type after resistors, capacitors and inductors, along with other Solid State memory devices, takes us one step further to creating cheap, powerful, distributed solutions for sensing and processing. A memristor (/ˈmɛmrɪstər/; a portmanteau of memory resistor) is a hypothetical non-linear passive two-terminal electrical component relating electric charge and magnetic flux linkage. It was envisioned, and its name coined, in 1971 by circuit theorist Leon Chua. According to the characterizing mathematical relations, the memristor would hypothetically operate in the following way: The.

A memistor is a nanoelectric circuitry element used in parallel computing memory technology. Essentially, a resistor with memory able to perform logic operations and store information, it is a three-terminal implementation of the memristor. It is a possible future technology replacing flash and DRAM. Applications of a Memristor Non-volatile memory applications. Memristors can retain memory states, and data, in power-off modes. Non-volatile random access memory, or NVRAM is the first application that comes to mind when we hear about memristors.

A memristor, or memory resistor, is described as one of the basic elements (resistor, capacitor, inductor) of electronic circuits, because it can’t be replaced by any combination of these elements. This element can change its resistivity according to the voltage, but even after disconnection it remembers resistivity for unlimited time. It can work like analog memory or a resistive switch, which can have an infinite number of states.

History

Professor Leon Chua mathematically described this element in 1971.In 2008 scientists from HP labs described a material that appeared to be a good candidate to construct the hypothetical memristor of Leon Chua.

How it works

The fourth element can change its conductivity by the voltage, and after power interruption the amount of the resistivity stays the same. No combination of the other three circuit elements can replace a memristor. Only the memristor allows reconfiguring properties so it allows changing a whole electronic circuit. Analogy behaviour is similar to synapses in the brain.

Future usage

Memristors have great potential for use in computers. For example, computers today have to boot from hard drives because the data is erased from operating memory immediately after shutting down the computer. The process of booting takes much time and energy. Memristors could be used for loading data quicker because it remembers data even after power interruption. Therefore, Memristors could be used to speed the booting process.

The first products using Memristor technology are expected to become available in 2013.^[1]
