The first plastic flexible magnetic memory chip came out
According to the message, an international team developed a novel technology, they transplanted high-performance magnetic memory chips into a piece of flexible plastic surface, and nondestructive its performance, the transparent film shape flexible plastic "" smart chip has excellent data storage and processing power, is expected to become flexible lightweight equipment design and development of key components. In the latest study, the scientists will first magnesia based magnetic tunnel junction (MTJ) grown on a silicon surface, then etched away below the silicon, then use a method of heat transfer in a flexible plastic surface made of polyethylene terephthalate, into a magnetic memory chips. New equipment in the magnetic resistance type random access memory (MRAM) operation show that the performance of the MRAM is better than the traditional random access memory computer chips in many ways, for example, higher processing speed, lower energy consumption, can be in stored data when the power is cut off, and so on. Flexible electronic devices are particularly eye-catching for flexible magnetic storage devices because they are key components for data storage and processing of wearable electronics and biomedicine devices. Although scientists have conducted multiple studies on different memory chips and materials, it still faces significant challenges to build high-performance memory chips on flexible plinths without compromising their performance. To do this, associate professor at the national university of Singapore Yang Xianxiu (transliteration) leadership yonsei university, the university of Ghent in Belgium, Singapore institute of materials research and engineering of this new technology is developed by scientists. "We are the first team to build magnetic memory on the flexible surface," Yang said. The experiment proved that the tunnel magnetic resistance of the new equipment could reach 300%, and we also managed to improve the control ability of the switch, so that this flexible core chip could transmit data more quickly. The team recently patented the technology in the United States and South Korea, where they are further promoting the device's magnetoresistance and planning to apply it to other electronic devices. The research is published in the latest issue of advanced materials.
