Abstract

The embodiments of the invention provide an apparatus, method, etc. for a non volatile memory RAD-hard (NVM-rh) system. More specifically, an IC permanent non-volatile storage element comprises an integrated semiconductor stable reference component, wherein the component is resistant to external radiation. The storage element further comprises e-fuse structures in the component and a sensing circuit coupled to the e-fuse structures. The sensing circuit is adapted to update an external device at a specified time interval to reduce incidence of soft errors and errors due to power failure. Moreover, the sensing circuit is adapted to cease updating the external device to program the e-fuse structures; and, continue updating the external device after programming the e-fuse structures.
