Scientists Have Turned A Single Molecule Into Flash Storage
Scientists have managed to turn a single molecule into flash storage. These devices are able to store memory in electrons that are caged. This invention can lead to usage of much smaller and rapid technology.
Memory storage has evolved with time. It began with etching of data on to discs of all sorts which is now an outdated and extinct method. Presently flash storage is utilized that allows users to electronically erase and reprogram it in accordance with their requirements.
A USB drive is a good example of such. Science and technology have managed to shrink these storage devices down to such a size but currently, scientists are in a struggle to shrink them below ten nano-meters per each data cell.
An international team of talented researchers has succeeded in taking things a step further. They have successfully stored data in a molecule. A flash storage is as big as three molecules in reality. It is constructed on two molecules that hold the electrons possessing the data while the third molecule serves as a small cage for them. Each portion of the cage is about a nanometer in length.
The team conducted an experiment to prove the concept. They made use of a tungsten molecule to serve the purpose of that cage in particular. They use selenium trioxide molecules for holding of the electrons. The set up was able to remain stable at temperatures as high as six hundred degrees Celsius. The set up was able to store those electrons for the longest recorded time tested of about 336 hours. The results of the brilliant experiment were published in Nature.
It is obvious that the research has just begun. These are in the very first stages of this long journey. It is still time to a point where users will be able to store all of their contacts onto molecules in caged form.
These scientists were lead by the team from the University of Glasgow are looking forward to progressing in this particular process. They are working to make the process even more efficient as presently the entire process needs huge amounts of energy (voltage) relative to other devices used in current times.
The scientist explained that the setting up process of the device along with the writing process took about tenths of seconds. In order to compete with the present storage devices, these molecular systems need to be much more efficient.
The researches have however predicted on the basis of their model that they will be able to set up the writing process on to these devices right down to picoseconds. It is being predicted that the path used by the electrons to be taken into the molecule is what determines the entire performance and speed.
Previously scientists have managed to come up with flash devices constructed from gaphene of single atom thick layers. The sheets, however, need stacking to work properly.
