Scientists at the Royal Melbourne Institute of Technology in Australia have developed a memory that can store information for a long time by simulating the process of processing human brain information. The device is considered to be the world's first electronic polymorphic memory, capable of simulating the ability of the human brain to store a variety of information while processing information, paving the way for the replication of brain and electronic bionic brains in vitro. Related papers were published in the latest issue of Advanced Functional Materials.
Dr. Sharis Slimam, who led the research, is one of the leaders of the School's Micro-Nano Research Center (MNRF) Functional Materials and Microsystems Research Group. He said that simulating long-term memory in the brain is an important breakthrough. The new study solves a key problem in the development of the simulated human brain, making the electronic bionic brain a step closer to reality. In addition, the study will help to treat the treatment of common neurological diseases such as Alzheimer's disease and Parkinson's disease.
Slimam said: "The human brain is a very complex analog computer... Its evolution is based on past experience. Until now, this function has not been fully reproduced by digital technology. This research is that we are creating electronics. An attempt to mimic the real brain in the process of bionic brain. It simulates the human brain to learn, store, and retrieve and extract information. This high-density, ultra-high-speed analog memory memory will become the basic component of the biological neural network and even the artificial brain."
The first author of the paper, Dr. Hussein Neri of the Royal Melbourne Institute of Technology, said that the important value of this new discovery is that it allows polymorphic cells to store and process information into reality, which is what the brain processes and stores. The way is very similar. He used an image comparison to illustrate the advantages of the new technology. "Previously, the memory of a computer was like the image obtained by a camera that can only capture black and white images, only black and white, and the new technology brought a contrast of light and dark. The color world of light intensity and object texture." This is an important breakthrough for computer information storage. Neri said: "Compared to traditional digital memories that can only store 0 and 1, these new devices can 'remember' more information, in addition to retaining and retrieving previously stored information. People are very excited."
The results were based on a study at the end of last year at the research center. They developed a nano-scale ultra-fast memristor with amorphous perovskite oxide that is 1000 times thinner than human hair. The device is able to "remember" previously saved information after a power outage.
Dr. Nile said that the scope of the study will be very broad, including the possibility of replicating an extracorporeal brain. In addition to helping the artificial brain, this replicating brain is also expected to help treat the brain and nervous system diseases, reducing the ethical issues associated with treatment and experimentation.
