A SIM card sized that stores human books.

A small electronic chip that can store a huge amount of data, using the properties of chlorine atoms, an invention that would revolutionize the storage of various data.


One of the characteristics of this chip is that it has the advantage of retaining incredible amounts of data compared to electronic chips intended for storage, using the properties of chlorine atoms, according to the journal Nature Nanotechnology.


The slide, which can be rewritten and can store information in single chloric atoms on a copper surface, developed by Dutch scientists under the supervision of scientist Sander Oo of Delft Technological University.


The researchers used the property of chlorine atoms to arrange the information on a two-dimensional lattice on a copper surface on each side on its own, Deutsche Welle’s Moukah said.


“Each (bit) of information typically consists of two positions on a surface of copper atom, and one chlorine atom that we can pull forward or backward between these two positions,” Oah explains how the information is stored.


“If the chlorine atom is at the top position, there will be a hole underneath it, we call it one and if the empty hole is in the top position and the chlorine atom is at the bottom the bit is within the definition of zero,” he adds.


Because chlorine atoms are surrounded by other chlorine atoms, other than positions near holes, they will keep each other in their exact location, that’s why the research team at Delft University believes their method is more stable than methods that use free atoms and more convenient to store information.


Scientists confirm that this small slide, which does not exceed the size of a small postage stamp, accommodates all the books of all humanity, according to the published study, as the researchers used the STM tunnel survey microscope in which a sharp needle explores the atoms on the surface one by one.


However, the possibility of storage is only at minus 196 degrees Celsius, and the storage method used, by pushing “programmed atoms” from one gap to another, until one information unit is created takes a lot of time, so copying all the world’s books on this chip “may take thousands of years” to complete this task, according to the magazine.


The researchers said it is currently difficult to connect this technology in regular computers or mobile phones, but Oh and his colleagues believe that this invention will pave the way for the development of new and different storage systems from what is currently on the market.
