Compare STT and SOT labels as mechanism cues, not commercial guarantees.

Switching is only one corner of the MRAM tradeoff.
Memory
MRAM needs a memory-hierarchy explanation: write energy, write time, switch probability, read margin, retention, and disturb risk pull against each other.
EVIDENCE SEQUENCE
What the learner should inspect first.
This surface connects the daily-scan source signal to an original SemiAgora simulation object without copying source text, code, figures, PDK files, or process recipes.
Move thermal barrier and pulse width while tracking write energy and read margin.

Inspect run card ->METHODS
Precomputed model contract.
The goal is useful study scaffolding and paper-planning discipline, not calibrated production evidence.
Normalized STT/SOT teaching model.
The simulation object keeps the same statement beside downloadable JSON and CSV evidence.
Triangle score combines switch probability, read margin, retention, energy, and disturb risk.
The simulation object keeps the same statement beside downloadable JSON and CSV evidence.
The simulation exports rows for later figure and methods drafting.
The simulation object keeps the same statement beside downloadable JSON and CSV evidence.
LIMITS
Useful, but deliberately bounded.
No account, upload, payment, comment, newsletter, live solver, facility workflow, or product-release surface is enabled.
No calibrated MTJ stack, stochastic LLG solve, endurance data, or array implementation.
Keep this boundary attached when reusing the card for lesson writing, figure planning, or research notes.
No claim that MRAM replaces SRAM, DRAM, Flash, or HBM.
Keep this boundary attached when reusing the card for lesson writing, figure planning, or research notes.
Real study needs measured device data, sense circuitry, write-error statistics, and retention/endurance conditions.
Keep this boundary attached when reusing the card for lesson writing, figure planning, or research notes.
SOURCE ANCHOR
Link-only public source spine.
SemiAgora uses the source as a signal and citation anchor, then writes original summaries and original toy data with explicit limitations.
