Abstract
A semiconductor memory device is disclosed. The semiconductor memory device may include a magnetic tunnel junction pattern, a spin-orbit torque (SOT) pattern in contact with a first portion of the magnetic tunnel junction pattern, a first transistor electrically connected to a second portion of the magnetic tunnel junction pattern and configured to be controlled by a first word line, and a second transistor electrically connected to a first end of the spin-orbit torque pattern and configured to be controlled by a second word line. An effective channel width of the first transistor may be different from an effective channel width of the second transistor.
