Technique that created the solid-state memory which can store 45 million songs on the surface of a quarter
Scientists have created the dense, solid-state memory that could exceed the capabilities of current hard drives by 1,000 times. It will also enable the memory to be rewritable, meaning it could lead to far more efficient types of solid-state drives for computers.
Ready for real-world use
Unlike, previous discoveries of atomic-scale computer storage which were stable only at extremely low temperatures, this new memory works at real-world temperatures and can withstand normal use.
As withstanding temperature restrictions, the technology can be used and transported to an end-user. It can be used for archiving data whereas next steps will include increasing reading and writing speed for more flexible applications.
Nanotip technology allowed scientists to manipulate single atoms on a silicon chip and this atom-scale fabrication will soon become a commercial reality in the near future.
To demonstrate the new memory, scientists encoded the entire alphabet at a density of 138 terabytes per square inch, roughly equivalent to writing 3,50,000 letters across a grain of rice. For a playful twist, they also encoded music reminiscent of video game soundtracks from the ’80s and ’90s.
