SIMULATION / SA-MEM-003-FEFET-HYSTERESIS-001
FeFET hysteresis, wake-up, fatigue, and usable window
FeFET Window
Replay cycle count, temperature, and program pulse to see how ferroelectric memory window can wake up, fatigue, and shift.
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.
- Keep hysteresis window, imprint shift, wake-up, fatigue, and retention language together.
- Compare early-cycle and high-cycle behavior before trusting one memory-window number.
- Use the card to prepare for FeRAM/FeFET literature without copying device data.
RUN CARD
Conditions before conclusions.
This page replays saved FeFET data and does not run a ferroelectric compact model or measured endurance flow.
Primary knobs
- Cycle count
- Temperature
- Program-pulse proxy
Saved outputs
- Memory window
- Imprint shift
- Usable window

How the number was made.
Methods are written for citation discipline: the extraction rule matters as much as the plotted value.
Memory window starts from a nominal hysteresis width, then includes wake-up, fatigue, and temperature-loss terms.
Keep this method attached when reusing the figure or metric.
Imprint shift increases with cycle count and temperature.
Keep this method attached when reusing the figure or metric.
Usable window subtracts imprint and a fixed sensing guardband from the memory window.
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 HfO2 stack, domain switching model, measured polarization, retention, endurance, or wake-up/fatigue dataset is included.
Carry this boundary into any derivative note, paper draft, or slide.
No process integration, embedded NVM, or product-memory claim is made.
Carry this boundary into any derivative note, paper draft, or slide.
Real FeFET work needs material stack, pulse protocol, measured hysteresis, and retention/endurance evidence.
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.
v64 deep results store every cycle, temperature, pulse, window, and imprint row.
