We propose an optical buffering technique for a programmable gate array under a space radiation environment. The technique allows rapid recovery of a programmable device that is damaged by high-energy charged particles. The technique uses invalid configuration data, including error bits that have already been damaged by the particles, while the configuration data are transferred using wireless communications and are retained on electronically erasable, programmable read-only, or static random-access-memory devices.
