Magnetic field induction, storage and calculation integrated structure based on magnetoelectric effect

Abstract

The invention discloses a magnetoelectric effect-based magnetic field sensing, storage and calculation integrated structure, which comprises a sensing layer, a storage layer, a calculation layer and a silicon multi-bit multiplexer logic layer, and is characterized in that the sensing layer, the storage layer, the calculation layer and the silicon multi-bit multiplexer logic layer are in ultra-dense connection through nanotubes; the magnetostriction layer in the magnetic field sensing assembly stretches out and draws back under the action of an external magnetic field, and stretching out and drawing back of the magnetostriction layer causes stretching out and drawing back changes of the piezoelectric layer. The piezoelectric layer stretches out and draws back so that potential difference exists between the two end faces, and the potential difference serves as a signal to reflect external magnetic field information. And the sensor units in all the sensing layers directly write data into the RRAM units in the lower storage layer in parallel. The operation condition of a power grid is judged through the distribution and change of an induced magnetic field, the magnetic field distribution is predicted in combination with artificial intelligence, and the use condition and the service life of equipment are accurately predicted.

Problems solved by technology

At present, the magnetic field sensor can only realize the function of magnetic field sensing, but the sensing is separated from the memory and calculation. The intermediate data transmission process needs to consume a lot of energy, and the volume is relatively large. It is used in integrated circuits.
