Assignee: INSTITUTE OF SEMICONDUCTORS, CHINESE ACADEMY OF SCIENCES
Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 0:
1. A function switchable random access memory, comprising:
two electromagnetic portions configured to connect a current;
a magnetic recording portion disposed between the two electromagnetic portions, wherein the magnetic recording portion comprises a spin-orbit coupling layer and a magnetic tunnel junction;
a pinning region disposed between each of the electromagnetic portions and the magnetic recording portion; and
a cut-off region disposed on a side of each of the electromagnetic portions opposite to the pinning region,
wherein the spin-orbit coupling layer is configured to generate a spin current under an action of the current;
wherein the two electromagnetic portions is further configured to generate two magnetic domains with magnetization pointing in opposite directions under an action of the spin current;
wherein the magnetic tunnel junction is configured to generate a magnetic domain wall based on the two magnetic domains with magnetization pointing in opposite directions; and
wherein the magnetic tunnel junction is further configured to drive the magnetic domain wall to reciprocate under the action of the spin current, so as to achieve the magnetization switching.
