Abstract
A new type of memory cell that uses domain wall motion is described. The magnetic configurations were revealed using a simulation, and were observed by a magnetic force microscope (MFM). The cell includes a magnetic tunnel junction (MTJ). The cell have two magnetization states, and they correspond to the domain wall position. The advantage of this memory cell is that the voltage stress to the tunnel barrier and the reading disturbance to the stored data are less than the general spin-injected MTJ cells.
