Memory chips that dissolve in water prevent data leaks
In the rapidly evolving Internet-of-Things era, data breaches are a serious concern. But local researchers have found a way to guard against data leaks, with the development of a water-soluble memory device.
Park Se-young has the details.
This memory chip is water soluble and it takes just ten seconds for it to dissolve. The device, developed by a research team at KAIST, offers the user both security and protection against unauthorized access.
"The memory device was produced on a water soluble substrate , which physically disassembles the chip as it dissolves."
The resistive random access memory chip was printed using an inkjet printer on a solid sodium glycerine paper, which reacts to even a small amount of water.
It was assembled at a temperature of 150 degrees Celsius or lower, so it maintains its stability in humidity.
The chip costs about one-tenth the price of producing similar kinds of chips that are affixed to a silicon base.
Although it's less durable than existing devices, that's likely a plus for some.
"What differentiates our study from previous ones is that we focused on quick disposal for the protection of personal information."
The soluble memory devices currently in use need to be burned in order to be destroyed.
The new chip, which shortens the disposal process by several seconds, was introduced in the online journal Scientific Reports.
