Abstract

A magnetic memory cell (100) includes a magnetic memory element (110) with at least one magnetic layer (111), configured to store information in distinct magnetization states. The magnetic layer (111) generates a stray magnetic field corresponding to its magnetization state. A magnetic field detection device (120) is positioned in proximity to the magnetic memory element (110) to detect variations in the stray magnetic field. The detection device (120) comprises a magnetostrictive (121) and piezoelectric (122) or a piezomagnetic (121) and piezoelectric (122) layer assembly. The magnetostrictive (121) or piezomagnetic (121) layer undergoes mechanical deformation in response to stray field changes, while the piezoelectric layer (122) generates an electrical signal representing the stored information. A writing mechanism (130) is configured to alter the magnetization state of the magnetic layer (111), enabling reliable data storage and retrieval.
