AUSTIN (Monitoring Desk) The world’s smallest data storage device made of two-dimensional (TODI) material and measuring the size of a nano-meter has been invented by researchers at the University of Texas at Austin. Scientists have called the ‘atom resistor’ after it. That is, it is a nuclear-scale transistor that stores data. This system operates by transferring single atoms, which enables the storing of information and data in very small memory units. This system belongs to Memester, the recently developing electronics sector.
Between the resistance switches, it keeps records. Its electrical resistance varies and weakens or becomes greater as a given voltage is applied to a specific material. For writing and deleting records, this phenomenon is used. And eventually, to read the stored data, the same resistance mechanism can be used. When one of the atoms in a nano-meter-scale hole moves in or out the conductivity of a substance varies.
In this way, at the nuclear stage, data can be scientifically stored. For this objective, molybdenum disulfide was used. But on many substances, including “atom resistors” can be made, the same method can not be attempted. It is as such the smallest memory in the world built on a nuclear scale. Experts broke molybdenum disulfide into parts one nano-meter long and one nano-meter high, around the size of an atom, to create this ‘atom resistor’.
This way, on a square centimetre slice, as many as 25 terabytes of data can be potentially stored. This is 100 times more than per square centimetre of the current flash memory power. Interestingly, for storage at the nuclear stage, energy is often needed. Details of this invention was published in Nature Nanotechnology, the latest issue of the Open Access Scientific Journal. For tasks such as neuromorphic computation, radio frequency communication, and holding data in a very small space, it may be important in the future as a data storage device.
