A single memristor is made of a positive and negative electrode, separated by a “switching medium,” or space between the electrodes. The size of the ion channel (and the signal that the memristor ultimately produces) should be proportional to the strength of the stimulating voltage.Kim says that existing memristor designs work pretty well in cases where voltage stimulates a large conduction channel, or a heavy flow of ions from one electrode to the other. Peng Lin.
But these designs are less reliable when memristors need to generate subtler signals, via thinner conduction channels.The thinner a conduction channel, and the lighter the flow of ions from one electrode to the other, the harder it is for individual ions to stay together. Search form.
The synapse receives signals from one neuron, in the form of ions, and sends a corresponding signal to the next neuron.A transistor in a conventional circuit transmits information by switching between one of only two values, 0 and 1, and doing so only when the signal it receives, in the form of an electric current, is of a particular strength.

When a voltage is applied to one electrode, ions from that electrode flow through the medium, forming a “conduction channel” to the other electrode.
Search . This would enable a single memristor to have many values, and therefore carry out a far wider range of operations than binary transistors.Like a brain synapse, a memristor would also be able to “remember” the value associated with a given current strength, and produce the exact same signal the next time it receives a similar current. We’re trying to build real neural network hardware for portable artificial intelligence systems,” says Jeehwan Kim, associate professor of mechanical engineering at MIT.

The signal it produces would vary depending on the strength of the signal that it receives. Kim’s team looked through the literature to find an element that they could combine with silver to effectively hold silver ions together, while allowing them to flow quickly through to the other electrode.The team landed on copper as the ideal alloying element, as it is able to bind both with silver, and with silicon.“It acts as a sort of bridge, and stabilizes the silver-silicon interface,” Kim says.To make memristors using their new alloy, the group first fabricated a negative electrode out of silicon, then made a positive electrode by depositing a slight amount of copper, followed by a layer of silver.

This could ensure that the answer to a complex equation, or the visual classification of an object, is reliable — a feat that normally involves multiple transistors and capacitors.Ultimately, scientists envision that memristors would require far less chip real estate than conventional transistors, enabling powerful, portable computing devices that do not rely on supercomputers, or even connections to the Internet.Existing memristor designs, however, are limited in their performance. “We would like to develop this technology further to have larger-scale arrays to do image recognition tasks. Search form. Credit: Peng Lin Full Screen A new MIT-fabricated “brain-on-a-chip” reprocessed an image of MIT’s Killian Court, including sharpening and blurring the … In a neuromorphic device, a memristor would serve as the transistor in a circuit, though its workings would more closely resemble a brain synapse — the junction between two neurons.
In contrast, a memristor would work along a gradient, much like a synapse in the brain. Search . As a result, it’s difficult for the receiving electrode to reliably capture the same number of ions, and therefore transmit the same signal, when stimulated with a certain low range of current.Kim and his colleagues found a way around this limitation by borrowing a technique from metallurgy, the science of melding metals into alloys and studying their combined properties.“Traditionally, metallurgists try to add different atoms into a bulk matrix to strengthen materials, and we thought, why not tweak the atomic interactions in our memristor, and add some alloying element to control the movement of ions in our medium,” Kim says.Engineers typically use silver as the material for a memristor’s positive electrode.
