Metal-Semiconductor Combination Aids Brain-Like Computing Architecture


One of the biggest challenges within computer architecture is the integration and synchronization of memory, storage, and processing in a single unit. A research conducted at the University of Groningen revealed that the amalgamation of ferromagnetic cobalt with the strontium titanate (SrTio3) semiconductor type could create an interface with amplified storage abilities. This would enhance neuromorphic computing architecture, thus, strengthening the domain of brain-inspired computing. The researchers state that the interface created by the aforementioned combination creates storage abilities through a spin-memristor.

Methodology Employed to Understand Computing Architecture

On interfacing the SrTiO3 semiconductor with cobalt, a non-volatile variable resistance is developed, and the resistance be regulated with the use of an electric field. On the other hand, when the abovementioned interface is brought under a magnetic field, the TAMR spin voltage changed dramatically. The resistance to electric field and the change in TAMR value at room temperature hasn’t been witnessed in other materials before this. A professor at the University remarks that the simplification of spin-memristor eases the process of combining memory, computing, and storage.  The complexities of the computing architecture have been the prime causes behind the failure of such a combination. Devices that employ this combination can be used in brain-like computer architecture.

Paving Way for Better Computing Architecture Systems

It would be cumbersome to know what happens at the interface of the semiconductor and cobalt. The researchers believe that once this discovery is made, they would be in a better position to add utility to the system. As a final statement, the researchers asserted the wellness of the human brain to store and process large chunks of information.
