Thin film magnetic memory device having communication function, and distribution management system and manufacturing step management system each using thereof

摘要

A thin film magnetic memory device includes an antenna section transmitting and receiving a radio wave to an from an outside of the thin film magnetic memory device. An inductance wiring constituting the antenna section has a metal wiring, and a magnetic film formed to correspond to a lower surface portion of the metal wiring or lower surface and side surface portions of the metal wiring. The magnetic film is formed in an original manufacturing step of the thin film magnetic memory device without providing a dedicated manufacturing step.
