SCIENCE - Nanoscale engineering could lead to faster, smaller, more stable electronic memories

Developing a so-called 'universal memory', or the perfect electronic memory, has long been the holy grail of electronic engineering. A universal memory should have a fast read and write speed, high reliability, low power consumption, and be compatible with other electronic components as well as non-volatile; that is, it should retain the data even when the device's power is switched off.
