New type of memory effect discovered in transition metal oxides

A new kind of memory effect discovered in two Transition Metal Oxides could carry important repercussions on technology and security. The multi-state nature of the memory effect, whereby more than one piece of information can coexist in the same space, could be harnessed for memory technology. And while deleted computer data can be recovered, at least partially, by talented hackers, the ‘erase-upon-reading’ property of this system could make an invaluable contribution to security technologies.
