A group of
scientists at Korea Advanced Institute of Science and Technology (KAIST)
has fabricated a working computer chip that is almost completely clear,
the first of its kind. The new technology, called transparent resistive
random access memory (TRRAM).
The new chip is similar
in type to an existing technology known as complementary metal-oxide
semiconductor (CMOS) memory common commercial chips that provide the
data storage for USB flash drives and other devices. Like CMOS devices,
the new chip provides "non-volatile" memory, meaning that it stores
digital information without losing data when it is powered off. Unlike
CMOS devices, however, the new TRRAM chip is almost completely clear."It
is a new milestone of transparent electronic systems," says researcher
Jung Won Seo, who is the first author on the paper. "By integrating
TRRAM device with other transparent electronic components, we can create
a total see-through embedded electronic system."
"We
are sure that TRRAM will become one of alternative devices to current
CMOS-based flash memory in the near future after its reliability is
proven and once any manufacturing issues are solved," says Professor
Jae-Woo Park, who is Seo's co-advisor and co-author on the paper. He
adds that the new devices have the potential to be manufactured cheaply
because any transparent materials can be utilized as substrate and
electrode. They also may not require incorporating rare elements such as
Indium.
The fabricated
TRRAM has a transmittance of 81% (including the substrate) in the
visible region and an excellent switching behavior under3 V. The
retention measurement suggests that the memory property of the TRRAM
device could be maintained for more than 10 years. We believe that the
TRRAM device presented in this work could be a milestone of future
see-through electronic devices.
I think in future the iphone may be like the below image..!! :P
