DAEJEON, Dec. 22 (Korea Bizwire) – A team of Korean scientists led by KAIST professor Bae Hag-youl announced Thursday that it has developed a water-disposable, non-volatile resistive random access memory (RRAM) chip using a water soluble SSG (solid sodium with glycerine) paper.
In a nutshell, the device dissolves in a matter of seconds once it is placed in a small amount of water, making the data contained on the chip impossible to recover or replicate.
With the advancement of technology, and the increased use of IoT devices, significant research has focused on developing more secure semiconductors that can best prevent sensitive information from falling into the wrong hands.
Conventional memory devices tend to take a longer time to destroy, while technology that uses paper boards to incinerate devices is limited by its need for a separate ignition mechanism and heat, the researchers said.
According to the team, the new device can be dissolved within just ten seconds. The team also used an inkjet printing technique to overcome vulnerability to moisture and heat, preventing any damage from everyday humidity, and allowing the chip to only react to water.
The team noted that its technology is applicable to a wide range of electronic devices, thanks to its flexibility, and the manufacturing cost is about one-tenth that of silicon-based options.
The full research findings were published in the December 6 online edition of Scientific Reports.
