12 atoms used to store a single byte of data

New research findings at I.B.M. allow for miniaturized data storage in atomic-scale antiferromagnets. The binary representation of 'S' (01010011) was stored in eight iron atom arrays.



IBM researchers have developed a way to store data at the atomic level.  By using an array of 12 atoms they have successfully written and read digital 1’s and 0’s.

Today’s most advanced storage technology requires around 1 million atoms to store the equivalent data.

The implications on storage capacity and energy consumption could be huge and allow for massive storage on tiny devices further empowering capabilities of all electronic devices.


Their experiment was done at very low temperatures, near absolute zero, but the researchers said it should be possible to at room temperature using as few as 150 atoms, still orders of magnitude less that technology available today.
