Boffins pioneer electron spin data storage Ohio State University boffins have built a device that stores data based on electron spin which uses less energy and is cooler than existing DRAM. Electrons can be forced to orient their magnetisation or spin in parallel (on) or anti-parallel (off) alignment by using an external magnetic field. The alignment, called spin up or …
All sorts of momory systems are vulnerable to ionizing radiation (the denser the storage for a given technology, the more vulnerable it is). The answer is well established - error correction algorithms. Throw enough redundant bits at the problem and place them such that no single event will wreck the data integrity and you have a solution. Of course as memory gets denser then it becomes cheaper to throw more bits into the error correction redundancy plot.
Evolution long ago learned long ago to make brains not vulnerable to single synapse failures.
But a hell of a long way from buying a device out the catalogue.
Still not quite sure from the article if this is a non volatile technology. Garnet films and actual particle (or virtual particle) motion put me in mind of magnetic bubble domain memories. Hopefully this will be more commercially successful.
Cautious thumbs up.
