#Researchers develop the first flexible phase-change random access memory (Nanowerk News) Phase change random access memory (PRAM) is one of the strongest candidates for next-generation nonvolatile memory for flexible and wearable electronics.
The effective solution is to decrease cell size in sub-micron region as in commercialized conventional PRAM.
thus practical flexible PRAM has not been realized yet. Recently a team led by Professors Keon Jae Lee
and Yeon Sik Jung of the Department of Materials science and engineering at KAIST has developed the first flexible PRAM enabled by self-assembled block copolymer (BCP) silica nanostructures with an ultralow current operation (below one quarter
of conventional PRAM without BCP) on plastic substrates. BCP is the mixture of two different polymer materials,
"Low-power nonvolatile PRAM for flexible and wearable memories enabled by (a) self-assembled BCP silica nanostructures and (b) self-structured conductive filament nanoheater.
KAIST) Another way to achieve ultralow-powered PRAM is to utilize self-structured conductive filaments (CF) instead of the resistor-type conventional heater.
"In addition, due to self-structured low-power technology compatible to plastics, the research team has succeeded recently in fabricating a flexible PRAM on wearable substrates.
"The demonstration of low power PRAM on plastics is one of the most important issues for next-generation wearable and flexible nonvolatile memory.
Our innovative and simple methodology represents the strong potential for commercializing flexible PRAM.""In addition, he wrote a review paper regarding the nanotechnology-based electronic devices in the June online issue of Advanced Materials entitled"Performance Enhancement of Electronic and Energy Devices via Block copolymer Self-Assembly
