Physically Unclonable Functions (PUFs) extract secure keys from inherent hardware variations, without storing them in non-volatile memory (NVM). SRAM PUFs leverage existing memory, but suffer from reliability issues due to noise. Current methods address this using complex error correction with NVM-stored helper data or by pre-selecting stable cells through repeated measurements. Avoiding NVM reduces leakage risks and manufacturing costs, benefiting low-end devices without NVM. This paper presents a novel self-contained approach for stabilizing SRAM PUFs without NVM-stored helper data, using a simple decoder and few SRAM measurements.
