Abstract
In one aspect of the present invention, a non-volatile latching element is provided that includes one or more magnetic elements therein. By programming the magnetic elements to appropriate resistance values, the latching element assumes a pre-programmed state upon power up. The magnetic elements are preferably programmed using either a one or two layer word line. In another aspect of the present invention, the magnetic elements are formed as pseudo-spin valve structures utilizing only CoFe as the active ferromagnetic layers, with one ferromagnetic layer thinner than the other. This simplifies the design while maintaining the high moment material to achieve large GMR ratios.
