SRAM-Based PUF Reliability Prediction Using Cell-Imbalance Characterization in the State Space Diagram
Gabriel Torrens, Abdel Alheyasat, Bartomeu Alorda +1
This work proposes a methodology to estimate the statistical distribution of the probability that a 6T bit-cell starts up to a given logic value in SRAM memories for PUF applicatio…
Estimation during Design Phases of Suitable SRAM Cells for PUF Applications Using Separatrix and Mismatch Metrics
Abdel Alheyasat, Gabriel Torrens, Sebastia A. Bota +1
Physically unclonable functions (PUFs) are used as low-cost cryptographic primitives in device authentication and secret key creation. SRAM-PUFs are well-known as entropy sources;…
A 65-nm Reliable 6T CMOS SRAM Cell with Minimum Size Transistors
Gabriel Torrens, Bartomeu Alorda, Cristian Carmona +3
As minimum area SRAM bit-cells are obtained when using cell ratio and pull-up ratio of 1, we analyze the possibility of decreasing the cell ratio from the conventional values compr…
An Affordable Experimental Technique for SRAM Write Margin Characterization for Nanometer CMOS Technologies
Bartomeu Alorda, Cristian Carmona, Gabriel Torrens +1
Increased process variability and reliability issues present a major challenge for future SRAM trends. Non-intrusive and accurate SRAM stability measurement is crucial for estimati…
