US 11,676,677 B2 · Magnetic storage device

Abstract

A magnetic storage device includes a magnetic body including first and second magnetic regions and a magnetic connection region that connects the first and second magnetic regions, and in which a plurality of magnetic domains each storing information by a magnetization direction thereof is formed, a read element that is electrically connected to the magnetic connection region and by which a magnetization direction of one of the magnetic domains is read, and a write element by which a magnetic domain having a magnetization direction is formed in the magnetic body according to information to be stored. The magnetic domains formed in each of the first and second magnetic regions are shifted in a predetermined direction in response to current that flows through the corresponding one of the first and second magnetic regions.
