SRAM assist taxonomy
Assist Taxonomy
Classify baseline write, cell-VDD collapse, wordline boost, negative bitline, and read wordline-underdrive as tradeoff cards instead of recipe settings.
EXPLORE
Start with the observable.
Use this page when the simulation is the primary artifact. The linked lesson explains the concept; the linked lab keeps the visual replay surface available.
- Compare which assist helps write margin and which protects read stability.
- Read energy index and coupling risk before treating margin gain as free.
- Use the taxonomy to name evidence needed for a real assist decision.
RUN CARD
Conditions before conclusions.
The page replays a saved taxonomy table. It does not publish voltage settings or operate assist hardware.
Primary knobs
- Assist family: baseline, write assist, read assist
- Metrics: write margin gain, read stability delta, energy index
- Risk language: coupling and neighboring-mode penalty
- Boundary: vocabulary and tradeoff, not recipe
Saved outputs
- assist classification
- margin tradeoff table
- risk language
- evidence-needed note

How the number was made.
Methods are written for citation discipline: the extraction rule matters as much as the plotted value.
Separate write assist from read assist before comparing margin numbers.
Keep this method attached when reusing the figure or metric.
Attach energy and coupling-risk language to every assist card.
Keep this method attached when reusing the figure or metric.
Describe the missing evidence required before any real SRAM assist claim.
Keep this method attached when reusing the figure or metric.
LIMITS
What this page does not claim.
The MVP is useful because the limits are visible. These statements prevent a teaching simulation from being cited as silicon evidence.
The assist table is a vocabulary and tradeoff replay; it is not a recommended SRAM assist design.
Carry this boundary into any derivative note, paper draft, or slide.
Numbers are normalized teaching values and must not be copied into a macro or chip implementation.
Carry this boundary into any derivative note, paper draft, or slide.
Driver circuits, boost generators, reliability stress, half-select behavior, timing closure, and variation are outside this dataset.
Carry this boundary into any derivative note, paper draft, or slide.
A real assist decision needs foundry models, array context, measurements, aging review, and product constraints.
Carry this boundary into any derivative note, paper draft, or slide.
EVIDENCE
Trace the claim back to artifacts.
The evidence route remains the catalog-level browser; this page is the simulation-level reading card.
The dataset records five assist taxonomy cards.
SA-MEM-DEPTH-ASSIST-001
Verification checks that no recipe voltage setting is published.
SA-MEM-DEPTH-ASSIST-001
The model card keeps VMIN and guardband language bounded as public education.
