MRAM switching energy versus retention
MRAM Switch
Replay STT/SOT-style write probability, pulse width, retention barrier, and write energy as a compact MRAM tradeoff card.
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.
- Move retention barrier and pulse width together to see why write energy is not independent.
- Compare STT and SOT labels as architecture cues, not as calibrated stack predictions.
- Use switch probability as a lesson proxy before studying micromagnetics or silicon data.
RUN CARD
Conditions before conclusions.
This page replays saved MRAM surrogate data and does not run a micromagnetic or LLG solver.
Primary knobs
- Mechanism label
- Thermal barrier
- Pulse width
Saved outputs
- Drive current proxy
- Switch probability
- Write energy

How the number was made.
Methods are written for citation discipline: the extraction rule matters as much as the plotted value.
Critical current scales with the normalized retention barrier and mechanism label.
Keep this method attached when reusing the figure or metric.
Switch probability uses a logistic teaching curve around the critical-current ratio.
Keep this method attached when reusing the figure or metric.
Write energy is computed from voltage, drive current, and pulse width.
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 calibrated MTJ material stack, stochastic thermal-noise LLG solve, or measured write-error data.
Carry this boundary into any derivative note, paper draft, or slide.
STT and SOT labels are teaching categories, not validated process/device options.
Carry this boundary into any derivative note, paper draft, or slide.
Use as vocabulary and tradeoff scaffolding before citing MRAM papers or foundry data.
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 stores the STT/SOT, barrier, pulse, probability, and energy rows.
