Patent ID: 7132707

Claim:
An MTJ MRAM cell element formed at an intersection of ultra-thin, magnetically clad word and bit lines comprising: an ultra-thin word line formed of magnetically clad high conductivity material, extending in a first direction within a first horizontal plane, said word line having an upper and a lower surface and having width w w and a thickness that is less than 100 nm; an ultra-thin bit line having an upper and a lower surface, a width w b and a thickness less than 100 nm, formed of magnetically clad high conductivity material, said bit line extending in a direction orthogonal to said first direction in a second horizontal plane that is vertically separated from said first horizontal plane, wherein said bit line and said word line thereby form a vertically separated intersection and are electrically insulated from each other; a horizontally multilayered magnetic tunnel junction (MTJ) cell element, having an upper and a lower surface and formed either above or below the intersection of said word line and said bit line and wherein said element electrically contacts said bit line.
