Abstrakt: Novel cell structures based on one transistor and two uneven magnetic tunnel junction cell and pillar write word line architecture are proposed to shrink the bit size with a potential down to 6 F² by a so-called extended via process, and to reduce the writing current by a factor of 2, combined with the nature of nonvolatility and high speed, making the magnetoresistive random access memory suitable for universal memory applications.
