Researchers Use Nanotechnology to Design Memory Storage Devices

Researchers have developed a new range of compact memory storage devices offering quick and energy saving memory for MP3s, smartphones and cameras.

Traditional methods utilize electronic devices to translate information into signals and are saved in the form of binary code. The new device utilizes a small mechanical arm to convert the information into signals. In contrast to the traditional memory storage devices, the latest device offers quicker functionality and also consumes minimum energy.

The new memory storage device saves information by measuring the amount of current flowing through a carbon nanotube and the corresponding binary value of the information is ascertained by an electrode that regulates the current flow.

University of Edinburgh researchers worked along with Konkuk University and Seoul National University researchers to develop the device. They have mentioned that the latest device could provide an innovative method of developing quicker devices consuming less power.

Earlier attempts of utilizing carbon nanotube transistors as memory storage devices were unsuccessful due to the low functional speed and brief memory retention period of carbon nanotube transistors. These problems have been avoided by utilizing a mechanical arm for charging the electrode.

The research received support from EaStCHEM and was published in the Nature Communications journal. Professor Eleanor Campbell of the University of Edinburgh's School of Chemistry participated in the research. He stated that utilizing a mechanical method linked with the advantages of nanotechnology has offered a memory storage device with high speed and energy competence in contrast to current devices.
