Germany uses nanotechnology to develop the world's smallest information memory

Recently, the world’s smallest information memory came out in Germany. German scientists used nanotechnology to successfully develop it. Although such magnetic nano-memory currently has extremely high requirements for the environment, it can maintain a stable state at -268 degrees Celsius. However, scientists hope that through further research, stability at room temperature can be achieved.

It is reported that the material used in the information memory is made by scientists using tunneling microscope probes to deposit iron atoms on copper nitrides. It is possible to use 12 ordered iron atoms in the electrical pulse to switch between the two magnetization states of 0 and 1 to store the information bit pattern, thereby forming tiny memory cells.

By accumulating the number of iron atoms, it is possible to gradually store bytes, although at least 500 million atoms can currently complete one byte of information storage. However, the information storage density of this information storage is very high, which is one of the reasons why scientists value this project. At present, scientists hope to further research and development to achieve stable magnetization at room temperature for future applications in the electronic information field.
