SRAM-based FPGA (Field Programmable Gate Array) is a reconfigurable LSI(Large Scale Integration).However, the configuration memory destroyed by a soft error due to radiation becomes a problem.To protect configuration memory against soft error , our original EDAC (Error Detecting And Correcting) was developped against soft error SBU(Single Bit Upset).However , EDAC ,which is intended for the SBU ,becomes powerless to MBU(Multiple Bit Upset).we propose to decompose the MBU in SBU with using interleaving to provide the tolerance against MBU for EDAC.
