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 with ECC, every input of ECC, is a segment of length composed of
After TMVS 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'
ECC has two inputs:
first segment is composed of
first 4/L cells biased towards '1'
last 4/L cells biased towards '0'
second segment
last 4/L cells biased towards '1'
first 4/L cells biased towards '0'
in this way, the ECC consumes less resources since it has less errors
