MEMRISTOR

Purpose of work:

• Find out what a memristor is.
• Where it is possible to use memristors.
• Differences from theoretical and practical memristor.
• As a memristor develops in Russia.

• Memristor (rus. Мемристор, from память - "memory", and резистор — «electrical resistance") — a passive element in microelectronics, able to change its resistance depending on the charge flowing through it (integral current during operation).

The theory of the memristor was created in 1971 by Professor Leon Chua. Born in 1936 Cai Satan in the Philippines among the ethnic Chinese who grew up in the same place in terms of the Japanese occupation.

• The memristor establishes relations between the time integrals of the current flowing through the element and the voltage on it.
• For a long time, the memristor was considered as the theoretical object that it is impossible to build.

• However, the laboratory sample of the memristor was created in 2008 by a team of scientists in the research laboratory of Hewlett-Packard (hp).
• Unlike the theoretical model, the device does not accumulate a charge like a capacitor and does not support magnetic flux like an inductor.

• Operation of the device is provided by chemical transformations in a thin 5 nanometer two-layer film of titanium dioxide.

• The phenomenon of hysteresis observed in the memristor allows it to be used as a memory cell.
• In principle, memristors can replace transistors in many cases, but this possibility is still considered only hypothetically.

• Theoretically, they can be more capacious and faster than modern flash memory.
• Their ability to" remember " the charge will allow to refuse loading of system.

• In the memory of the computer is disconnected from the power supply to store its latest state.

• It will be possible to turn it on and get started from where it left off.

• This property will allow us to abandon some components of the modern PC, which will make computers smaller and cheaper.

Development of memristor in Russia

• A memristor was obtained at Tyumen state University within the framework of the project on modeling of brain neural networks implemented by TSU and TASO LLC.

• Memristors were synthesized with the help of the modular technological platform acquired by TSU for the formation of nanotechnological complexes with the cluster arrangement "NANOFAB-100".

• Memristors today are the only non-living material, approaching its functions to the synapses of the living brain.
