Abstract
Provided are a magnetic random access memory cell and a magnetic random access memory. One form of a memory cell includes: a spin-orbit torque (SOT) layer, through which a write current flows when performing a write operation on the magnetic random access memory cell, a direction of the write current being a first direction, and a direction parallel to the SOT layer and perpendicular to the first direction being a second direction; and a magnetic tunnel junction, located on the SOT layer, the magnetic tunnel junction including substructures symmetrical with respect to the second direction, and a magnetic moment direction of the substructure forming an acute included angle with the first direction.
