RRAM, PCM, and FeFET read-margin degradation
eNVM Margin
Replay endurance, temperature, variability, and normalized read margin across RRAM, PCM, and FeFET style memory labels.
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.
- Treat emerging memory as a margin distribution problem rather than a single technology label.
- Compare endurance and temperature before ranking RRAM, PCM, or FeFET.
- Use the worst-case proxy to ask what metrology or compact model would replace this toy model.
RUN CARD
Conditions before conclusions.
This page replays saved emerging-memory surrogate data and does not run material or compact-model solvers.
Primary knobs
- Technology label
- Cycle count
- Temperature
Saved outputs
- Normalized read margin
- Read-error proxy
- Worst-case row

How the number was made.
Methods are written for citation discipline: the extraction rule matters as much as the plotted value.
Base margin is reduced by a log-cycle term and a temperature-loss term.
Keep this method attached when reusing the figure or metric.
Read-error proxy uses a simple exponential margin-over-variability mapping.
Keep this method attached when reusing the figure or metric.
Technology labels carry different base margin, variability, and drift constants for comparison only.
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.
No filament, phase-change crystallization, ferroelectric polarization, retention, or disturb physics is calibrated.
Carry this boundary into any derivative note, paper draft, or slide.
No production endurance, qualification, or technology-selection claim is made.
Carry this boundary into any derivative note, paper draft, or slide.
Use external papers and measured distributions before making a device choice.
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.
Seed sweep JSON records every technology, cycle, temperature, margin, and error-proxy row.
