Abstract:
Improved spin hall MRAM designs are provided that enable writing of all of the bits along a given word line together using a separate spin hall wire for each MTJ. In one aspect, a magnetic memory cell includes: a spin hall wire exclusive to the magnetic memory cell; an MTJ disposed on the spin hall wire, wherein the MTJ includes a fixed magnetic layer separated from a free magnetic layer by a tunnel barrier; and a pair of selection transistors connected to opposite ends of the spin hall wire. An MRAM device and method for operation thereof are also provided.
