Sub-quarter micron SRAM cells stability in low-voltage operation: a comparative analysis
Bibliographic record
Abstract
Comparative analysis of the conventional 6T and recently proposed loadless 4T CMOS SRAM cells is performed. Based on HSPICE simulations for 0.18-/spl mu/m technology, we compared the stability of the aforementioned cells to temperature and process (V/sub TH/, L/sub eff/, T/sub OX/) variations as well as the cells robustness in low-voltage operation. We found that at V/sub DD/ = 1.2 V the loadless 4T cell has a 20% higher static noise margin (SNM) and 1.5 times lower sensitivity to the V/sub TH/ fluctuations than the 6T cell. On the other hand, the 4T cell has a stronger read current degradation at reduced V/sub DD/. The analytical model for SNM calculation of the loadless 4T CMOS SRAM cell has been developed.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
