American researchers have found that the application of buckyballs to flash memory - the storage medium used in mobile phones and digital cameras - can enable flash memory to work under low voltage. This not only saves energy, but also extends the lifespan of the flash memory. According to the latest issue of the British journal Nature, researchers from Cornell University in New York, USA, have for the first time applied the principles of molecular electronics to flash memory, one type of non-volatile memory. By incorporating buckyballs into the structure of flash memory, the researchers enhanced the current during data reading, writing, or deletion, thus requiring only a lower voltage when writing or deleting data.
