Abstract
A 0.4 V single cycle 75 kbit SRAM macro protected with a multi-bit upset (MBU) correcting circuit is fabricated in a 28 nm LP-CMOS process. The novel error correcting circuit (ECC) is capable of 3-bit adjacent error correction and 8bit adjacent error detection. Simulation results show that the code provides a 2.35x improvement in corrected soft error rate (SER) over a Bose-Chaudhuri-Hocquenghem (BCH) double error correcting (DEC) code at a raw-SER of 1300 FIT/Mb while requiring 3 fewer check-bits. Further an alternative 2-bit adjacent error correcting implementation provides an corrected-SER approximately equal to the BCH DEC code for the same check-bit overhead as a single error correcting double error detecting (SEC-DED) code in the same error channel. Measurement results confirm an average active energy of 0.015 fJ/bit and leakage current of 10.1 pA/bit.

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
