Abstract
A ferromagnetic thin-film based digital memory (FIG. ) having in a bit structure ( ) a coupled moment material film ( ) in which magnetic moments of adjacent atoms, ions or molecules are coupled to one another to maintain some alignment thereof below a critical temperature above which such alignment is not maintained, and also having a plurality of word line structures ( ) each located across from the coupled moment material film ( ) in a corresponding one of the bit structures ( ). The bit structures ( ) are sufficiently thermally isolated to allow currents in the adjacent word lines ( ) and/or the bit structure ( ) to heat the bit structure ( ) to approach the critical temperature which may be supplied coincidently and then reduced to cool the bit structure ( ) while supplying a magnetic field during the cooling.
