Abstract

fetched live from OpenAlex

We introduce a novel family of asymmetric dual-Vt SRAM cell designs that reduce leakage power in caches while maintaining low access latency. Our designs exploit the strong bias towards zero at the bit level exhibited by the memory value stream of ordinary programs. Compared to conventional symmetric high-performance cells, our cells offer significant leakage reduction in the zero state and in some cases also in the one state albeit to a lesser extend. A novel sense-amplifier, in coordination with dummy bitlines, allows for read times to be on par with conventional symmetric cells. With one cell design, leakage is reduced by 7X (in the zero state) with no performance degradation. An alternative cell design reduces leakage by 40X (in the zero state) with a performance degradation of 5%.

Teacher imitation

Not 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.
