Title of the paper: A Two-Stage TMV SRAM PUF Preselection Method with Fewer ECC Resources Available at: https://ieeexplore.ieee.org/abstract/document/10503621 |
In summary, this paper combines TMVS TMV with ECC, every input of ECC, is a segment of length composed of
After TMVS TMV we have 4 segments:
first 4/L cells biased towards '1'
last 4/L cells biased towards '1'
last 4/L cells biased towards '0'
first 4/L cells biased towards '0'
...
in this way, the ECC consumes less resources since it has less errors
This paper has a major error: they used 4/L instead of L/4, where L is the length of the PUF response
