In Brief
Nano Data Storage and Battery in One
The Jülich-Aachen Research Alliance (JARA) team around Rainer Waser has found out that so-called resistive memory cells (ReRAM) function also as a battery. So far, the tiny memory cells were considered to be purely passive elements. The discovery opens up new possibilities for optimised production and practical application. The innovative electronic data storage devices have the potential to be significantly more powerful yet requiring less energy than currently used types of memory. Instead of electrons they use ions for storing data, thus allowing for a more compact design.
