Korean scientist invents transparent memory

South Korean scientists have used graphene to invent a transparent memory. In the future, laptops and smart phones will hopefully become transparent.

South Korean media ETNews reported on the 24th that the Ministry of Science and Information Technology of the Republic of Korea (ICT and Future Planning, MISP) announced on the 23rd that Kim Tae-geun and Kim Hee-, professors of the Department of Electrical Engineering at Korea University (Korea University) Dong has jointly developed a transparent memory manufacturing technology that uses a reduced graphene oxide with good conductivity and light transmission to increase transparency by 80%.

If you want to make transparent electronic products, the most important thing is to create a transparent non-volatile memory. Tantalum has been the main raw material for making non-volatile memory, but this material is not transparent.

In the past, many scientists had wanted to make transparent memory with graphene, but they could not develop devices with ideal storage capacity and resistivity. The transparent memory invented by Korea University’s research team can store data in a high-temperature environment at 85 degrees Celsius, and its operation time is at least 100,000 seconds. It is expected to be the core technology needed for transparent notebooks to store large amounts of data in the future.
