Abstract
Cosmic neutron-induced single event upsets have become a dominant failure mechanism in sub-100 nm CMOS memory and logic circuits. In this paper two SEU-robust flip-flops are described which are based on a hardened storage cell, known as the Quatro cell. One flip-flop utilizes C <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> MOS gates while the other utilizes a pulsed-latch architecture. The proposed flip-flops exhibit as much as a 50% improvement in power-delay product when compared with recently reported hardened flip-flops. A test chip containing the proposed flip-flops arranged in a shift register configuration was fabricated in a 65 nm CMOS process. Accelerated neutron radiation testing results show that the proposed flip-flops have excellent soft-error robustness.

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 it
