Abstract: Embodiments of this application provide a storage component, a preparation method, a reading/writing method, a storage chip, and an electronic device, is related to the storage technology field, and is used to resolve a problem that a quantity of storage states of a spin orbit torque-magnetic random access memory is increased while a storage state change range remains unchanged. The storage component includes: a first magnetic tunnel junction, a spin orbit coupling layer and a second magnetic tunnel junction that are sequentially arranged in a stacked manner. The first magnetic tunnel junction includes a first free layer, and the second magnetic tunnel junction includes a second free layer. The first free layer and the second free layer are arranged on two opposite surfaces of the spin orbit coupling layer.
