In space environments and at nuclear power plants, data can be destroyed by radiation, even data recorded on flash memories. To realize a radiation-hardened configuration context for field programmable gate arrays (FPGAs) under such radiation environments, this paper presents a proposal of a method to increase the radiation tolerance of configuration contexts used for FPGAs by introducing a holographic memory technology and a new FPGA architecture. When reading a configuration context from holographic memory, the context robustness depends on the number of bright bits on the configuration context. Our proposed method exploits that holographic memory property and uses a new FPGA architecture to fit the property to increase the radiation tolerance of configuration contexts from holographic memory. This paper presents simulation results and an experimental demonstration result.
