Abstract
A data system includes an information bus, a volatile memory located on the information bus, and an MRAM located on the information bus. The data system includes threat detection circuitry. In response to a threat condition to the MRAM, data is transferred via the information bus from the MRAM to the volatile memory for storage during a threat to the MRAM as indicated by the threat condition. In some examples, the threat condition is characterized as a magnetic field exposure.
