A memristor (/ ˈ m ɛ m r ɪ s t ər /; a portmanteau of memory resistor) is a non-linear two-terminal electrical component relating electric charge and magnetic flux linkage.It was described and named in 1971 by Leon Chua, completing a theoretical quartet of fundamental electrical components which also comprises the resistor, capacitor and inductor.
While the memristor is defined in terms of a two-terminal circuit element, there was an implementation of a three-terminal device called a memistor developed by Bernard Widrow in 1960. Memistors formed basic components of a neural network architecture called ADALINE developed by Widrow. [1] [2] The memistor was also used in MADALINE.
Leon Chua argued that all two-terminal non-volatile memory devices including ReRAM should be considered memristors. [20] Stan Williams of HP Labs also argued that ReRAM was a memristor. [21] However, others challenged this terminology and the applicability of memristor theory to any physically realizable device is open to question.
It is a combination of the memristor and transistor technology. [2] This technology is different from the 1T-1R approach since the devices are merged into one single entity. Multiple memristors can be embedded with a single transistor, enabling it to more accurately model a neuron with its multiple synaptic connections.
A real-estate lock box is a padlock-shaped box that generally hangs around the doorknob of a house that is on the market. The device holds the keys to a house to allow communal access for all real estate agents , while continuing to keep them secure. [ 1 ]
Neuromorphic devices have also been demonstrated using nanocrystals, nanowires, and conducting polymers. [27] There also is development of a memristive device for quantum neuromorphic architectures. [28] In 2022, researchers at MIT have reported the development of brain-inspired artificial synapses, using the ion proton (H +), for 'analog deep ...
Chua's memristor (1971) was based on a mathematical model for a fourth non-linear 2-terminal passive circuit element but did not represent a real device at the time. Chua and Kang extended the memristor concept to cover a larger class of memory circuits in 1976 and this is what HP's memristor basically represents.
In electronics, the relationship between the direct current (DC) through an electronic device and the DC voltage across its terminals is called a current–voltage characteristic of the device. Electronic engineers use these charts to determine basic parameters of a device and to model its behavior in an electrical circuit. These ...
