Patent attributes
A magnetic memory device and methods thereof are provided. The example magnetic memory device may include a transistor disposed within a given unit cell region and a magnetic tunneling junction (MTJ) element connected to the transistor, the MTJ element including an MTJ cell and first and second pad layers forming a magnetic field at first and second ends of the MTJ cell, the transistor including a drain connected to the first pad layer in the given unit cell region and a bit line, a source connected to the second pad layer in an adjacent unit cell region, and a gate connected to a word line corresponding to the given unit cell region. A first example method may include writing data into a MTJ element by polarizing a selected memory region connected to a word line, a first magnetic field at a first end of the MTJ element controlled by a first transistor corresponding to the selected memory region and a second magnetic field at a second end of the MTJ element controlled by a second transistor associated with an adjacent MJT element, the adjacent MJT element connected to the same word line as the MJT element. A second example method may include applying a first current to a first portion of a MTJ element on a first path from a word line to the MTJ element and applying a second current to a second portion of the MTJ element on a second path from the word line to the MTJ element, each of the first and second currents lower than a current threshold, the current threshold being a minimum current for initiating a polarization of the MTJ element, and a sum of the first and second currents at least equal to the current threshold.
