Spanish researchers have developed a material that mimics how the brain stores information

The way the brain stores information is possible to mimic thanks to neuromorphic computing, which works on the study of this type of technology. Recently, some researchers from the Autonomous University of Barcelona (UAB) have managed to develop a magnetic material that simulates and is able to simulate the synapses of neurons. Learning that occurs during deep sleep.

The study was led by researchers from the UAB Department of Physics Jordi sort You Enrique Menendezand with the participation of Zhengwei Tan, Julius De Rojaso You Sofia Martins, ALBA Synchrotron, in collaboration with the Catalan Institute of Nanoscience and Nanotechnology (ICN2) and ICMAB. Thanks to reproducing the main synaptic functions of neurons, they have devised a new way of controlling magnetization both in the stimulus state and after stimulation.



content is based a thin layer of Cobalt Mononitruron (CoN), With the use of an electric field, researchers have managed to control the accumulation of ions between the layer and a liquid electrolyte already submerged in the material.

Jordi Sort explains that the material “works with the motion of ions controlled by an electrical voltage, similar to that of our brain, and to the motion produced in neurons”. According to the professional, this may be the “basis” of the artificial synapse. A new alternative computing paradigm used by current computers,

On the UAB website, they explain that their technology is able to mimic “in a controlled manner, processes such as memory, information processing, information retrieval and, for the first time, the controlled updating of information without applied voltage”. it’s all possible Modulating the thickness and frequency of pulses of cobalt mononitride layers.


He shared this picture of Osprey.

“When the thickness of the cobalt mononitride layer is less than 50 nanometers and with an applied voltage at a frequency of more than 100 cycles per second, We have managed to simulate an additional argument function: Once a voltage is applied, the device can be programmed to learn or forget, without requiring any additional energy input, mimicking the synaptic functions that occur in the brain during deep sleep, when processing information without There may be continued indications of any external use,” the researchers stressed.
