Title:
MAGNETIC MEMORY AND METHOD FOR WRITING DATA INTO MAGNETIC MEMORY ELEMENT
Document Type and Number:
WIPO Patent Application WO/2016/063448
Kind Code:
A1
Abstract:
In order to stably write data in a magnetic memory in which data is written using in-plane current-induced perpendicular switching of magnetization, the magnetic memory is provided with: a recording layer formed as a perpendicular magnetization film; an adjacent layer joined to an upper surface or a lower surface of the recording layer; an external magnetic field application part configured to apply a first external magnetic field to the recording layer in a first direction that is an in-plane direction of the recording layer; and a current application part configured to pass a write current through the adjacent layer in the first direction or a second direction opposite to the first direction. The external magnetic field application part is configured to reverse the direction of a second external magnetic field to be applied in a direction perpendicular to the first direction depending on the direction of the write current.
