A team at Cambridge University working in conjunction with Hitachi have come up with the ugly sounding PLEDM. Ugly it might be, but it's better than the mouthful Phase-State Low-Electron Drive Memory.
PLEDM uses very small numbers of electrons to switch states, and can thus be fast, inherently low power and, according to Hitachi, could be developed to retain memory even with power switched off (known as non-volatile memory).
Chips using the design, which has been dubbed Phase-state Low Electron (hole)-number Drive Memory (PLEDM), could be used in high capacity mobile storage devices and replace current storage devices such as PC hard drives.
