Abstract:
Self-referenced magnetic random access memory (MRAM) cell including a magnetic tunnel junction including a sense layer; a storage layer having a storage magnetization; a tunnel barrier layer between the sense and the storage layers; and an antiferromagnetic layer exchange-coupling the storage layer such that the storage magnetization can be pinned when the antiferromagnetic layer is below a critical temperature and freely varied when the antiferromagnetic layer is heated at or above the critical temperature. The sense layer includes a first sense layer having a first sense magnetization, a second sense layer having a second sense magnetization and spacer layer between the first and second sense layers. The MRAM cell can be read with low power consumption.
