Title:
MAGNETIC STORAGE UNIT AND MAGNETIC STORAGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/178595
Kind Code:
A1
Abstract:
Provided in the present invention are a magnetic storage unit and a magnetic storage device. The magnetic storage unit comprises: a first free layer, a first coupling layer, a second free layer, a barrier layer and a reference layer, which are sequentially arranged in a stacked manner. A logic storage state of the magnetic storage unit is determined according to resistance states at two ends of the magnetic storage unit; and by means of applying a voltage pulse, the pulse width of which exceeds a pulse width threshold value, to the two ends of the magnetic storage unit, the resistance states at the two ends of the magnetic storage unit are subjected to unipolarity switching. In the present application, a pulse voltage is used to drive the magnetic storage unit to turn over; the present application has the advantages of low power consumption and high storage density; and there is no need to accurately control the pulse width of the voltage pulse, such that the difficulty of control over the pulse width is reduced.
