Abstract
A multibit MRAM cell including a magnetic tunnel junction including a sense layer having a freely orientable sense magnetization; a tunnel barrier layer; and a synthetic antiferromagnet storage layer having a first and second storage layer. The sense magnetization induces a dipolar field having a magnitude above a spin-flop field of the storage layer. The MRAM cell also includes aligning means for aligning the sense magnetization in a plurality of distinct orientations such as to encode a plurality of distinct logic states in the MRAM cell. The present disclosure also concerns a method for operating the multibit MRAM cell.
