Decoding the Past: Recovering Sensitive Data from SRAM Aging Imprints
DescriptionLong-term data remanence in SRAMs can pose serious security risks when discarded ICs retain sensitive information. Unlike DRAM and Flash memories, SRAMs have been largely overlooked in this field due to their very short retention periods. Prior works demonstrated that aging-induced imprints enable partial data recovery in SRAMs, but only when recorded initial power-up states are available. In this paper, we have proposed a recovery approach that eliminates this requirement by reconstructing initial states through controlled aging. By analyzing the reconstructed and aged power-up states, we demonstrated near-complete data recovery from SRAM chips after 12 hours of controlled aging using only 32 copies.
