Abstract
The disclosed technology relates to a magnetic domain wall-based memory device including a combination of at least one magnetic domain wall track and at least one spin orbit torque (SOT) track, which are arranged in a crossing architecture. The SOT track can include a first strip of a patterned SOT generating layer, wherein the first strip extends into a first direction and is configured to pass a first current along the first direction. The magnetic domain wall track can include a second strip of the patterned SOT generating layer and a first magnetic strip of a patterned magnetic free layer, wherein the second strip extends along a second direction and intersects with the first strip in a first crossing region. The first magnetic strip can be provided on the second strip including the first crossing region and can be configured to pass a second current along the second direction. Further, a first and a second MTJ structure can be provided on the first magnetic strip and can be separated in the second direction. The first MTJ structure can be provided above the first crossing region and can be provided with a first voltage gate.
