Discovery of a 'holy grail' with the invention of universal computer memory
[An] electronic memory device -- described in research published in Scientific Reports -- promises to transform daily life with its ultra-low energy consumption. [...] The device is the realisation of the search for a "Universal Memory" which has preoccupied scientists and engineers for decades.
Physics Professor Manus Hayne of Lancaster University said: "Universal Memory, which has robustly stored data that is easily changed, is widely considered to be unfeasible, or even impossible, but this device demonstrates its contradictory properties."
A US patent has been awarded for the electronic memory device with another patent pending, while several companies have expressed an interest or are actively involved in the research.
The inventors of the device used quantum mechanics to solve the dilemma of choosing between stable, long-term data storage and low-energy writing and erasing. The device could replace the $100bn market for Dynamic Random Access Memory (DRAM), which is the 'working memory' of computers, as well as the long-term memory in flash drives.
[...] Professor Hayne said: "The ideal is to combine the advantages of both without their drawbacks, and this is what we have demonstrated. Our device has an intrinsic data storage time that is predicted to exceed the age of the Universe, yet it can record or delete data using 100 times less energy than DRAM."

The article quotes someone saying "exceed the age of the universe", yet the actual paper says "Non-volatile data retention of at least 10^4 s", with no reports of tests lasting more than around an hour. Unless I'm experiencing an incredible amount of time dilation, there's a big difference between an hour and the lifetime of the universe...

When I saw the 10^4 sec, I thought, "hmm... about 3 hours." Low-volatility but definitely not non-volatile.
