Abstract
Charge-trap transistors (CTTs) are compute-in-memory devices that are used to model synaptic arrays in neuromorphic systems. CTTs enable non von Neumann architectures, thus, eliminating the energy spent on compute-memory communication. Synaptic weights can be stored in CTTs by shifting the threshold voltage of the devices in an analog manner. CTTs are, however, susceptible to unintentional de-trapping of charge over time due to threshold voltage instability, leading to loss of the stored synaptic weights. The proposed weight refresh system performs statistical refresh of the CTT array to replenish the charge of individual CTT devices (restore synaptic weights) based on characterization of threshold voltage instability in high-k dielectrics.

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
