Patent ID: 11929105
Assignee: CHANGXIN MEMORY TECHNOLOGIES, INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 5:
6. A magnetic memory, comprising a plurality of cell lavers, each of the plurality of cell layers comprising:
a plurality of parallel first wires, disposed in a first plane,
a plurality of parallel second wires, disposed in a second plane, the first plane being parallel to the second plane, and projections of the second wires onto the first plane intercrossing the first wires:
a plurality of storage elements, disposed between the first plane and the second plane, the storage elements comprising magnetic tunnel junctions and bi-directional gating components connected in series along a direction perpendicular to the first plane, the magnetic tunnel junctions being connected to the first wires, the bi-directional gating components being connected to the second wires, and the bi-directional gating components being configured to be conductive upon application of at least one of a threshold voltage or as threshold current; and
a control module, for providing a first current and a second current during a write operation, the first current passing through the first wires but not through the storage elements, the second current passing through selected storage elements, and the first current and the second current equalizing trends for resistances of the magnetic tunnel junctions to increase or decrease,
wherein the plurality of cell layers are sequentially arranged along the direction perpendicular to the first plane, adjacent cell layers share a same and single wire, Wherein the wire is used in upper-level cell layers and lower-level cell layers both as the first wire or the second wire.
