Scientists Cook Up See-Through Memory

Paul Lilly

Research in transparent electronic devices isn't anything new, but for the first time (that we're aware of), a group of scientists have created what they say is an "almost completely clear" computer chip. Credit goes to the Advanced Institute of Science and Technology (KAIST) team responsible for creating the see-through transparent resistive random access memory (TRRAM) based on maturing RRAM technology. RRAM technology is currently being developed by companies like Fujitsu, Samsung, Micron, and Spansion as a non-volatile memory technology that will attempt to replace flash, TGDaily says .

The KAIST team said its TRRAM device is based on an ITO (indium tim oxide)/ZnO/ITO capacitor structure with a transmittance of 81 percent in the visible region of the chip. Creating the chip consisted of essentially sandwiching the RRAM's metal oxide materials between equally transparent electrodes and substrates, which gives the chip its transparency. According to the researchers, the chip is capable of retaining data for 10 years.

There hasn't been a ton of interest in clear electronics up to this point, but the KAIST team is hopeful their discovery might change that. Eventually, the technology could enable the development of clear computer monitors and TVs that are embedded inside glass.
