Note: Lithographic methods (nanoelectronics) are now used to prepare some very powerful memories. The science and technology of nanoelectronics provide different possibilities  of nano molecular memory  . In fact, by using nano technology, the storage capacity of information can be increased by a thousand times or more. 
Nano Memory Moulcolar  is a transparent flexible nanographene floating gate transistor nano memory device that is made by combining a single-layer graphene active channel with gold nanoparticle charge trap elements. Systematically ,  the sizes of gold nanoparticle charge trap elements, the thickness of the tunneling dielectric layer and the doping level of graphene are very important in its production. In particular, the conductance differences (  ie  , memory window) between program and erase operations at a given read gate voltage can be maximized through doping. Graphene nano memories The resulting molecularly developed, nanoscale programmable memory has excellent performance compared to previous graphene memory devices and a large memory window (12 V), fast switching speed (1 μs), strong electrical reliability. it shows. The phenomenon at work here is called giant magnetoresistance, which refers to the effect of magnetic fields on electrical resistance. Depending on the magnetic polarization (whether the data bit is a one or a zero), the electrical currents recorded in the read head will differ. Graphene molecular nano-memory is  a new non-volatile charge trapping memory using isolated and uniformly distributed graphene nano-crystals as a nano-floating gate with controllable capacity and excellent uniformity. The nanographene charge-trapping memory exhibits large gate memory (4.5 V) at low operating voltage (8 V), chemical and thermal stability (1000 °C), as well as tunable memory performance using differential tunneling. .


The range of nanoparticle activity change depends on the nature and shape of the nanostructure. However  , if the energy of the nanoparticle field is comparable to the energy of electromagnetic radiation and if  significant changes are made in a certain wavelength range with the occurrence of chemical reactions in the irradiated materials, the activity  of nanoparticles up to 100nm will be significant. One of the new means of information storage is the use of nickel quantum dots in nanometer sizes, which are expected to be used for storage. Quantum nanoscale  effects are important in most materials and create different properties than what we are familiar with at the macroscopic scale. Nanophysics forms the basis of many phenomena of medicine, biological sciences and chemistry and is an important interface with these sciences.Electronic and optical properties and surfaces of various materials are interesting and new. Nano-Quantum is  based on the continuous development and refinement of nano-scale imaging techniques whose resolution reaches the atomic scale. Nanoelectronics enters into new materials and different fields of nutrition technology, (nano-scale measuring devices, tools for medical diagnosis, energy efficiency and storage and solar technology)  Quantum physics phenomena can be done with electrons, atoms or Photons and observed in dense matter systems such as metals or semiconductors that play an important role in our daily life. In the nano-quantum world, we observe many surprising and at first glance unusual phenomena - such as quantum particles that cannot collide in different places at the same time, or quantum jumps whose exact timing is essentially random. . As confusing as these phenomena may seem, we are already seeing signs that will form the basis of the modern technological revolution. There is almost no other field of science that so seamlessly intertwines basic research and pure technological applications and revolutionary impact as nanoelectronics. 



Conclusion :

The attractiveness of nanotechnology comes from the unique quantum and surface phenomena that matter exhibits at the nanoscale and enables new applications and interesting materials. The goal of evolutionary nanotechnology is to improve existing processes, materials and applications by shrinking in the nano realm and finally fully exploiting the unique quantum and surface phenomena that matter shows on the nano scale.
