SIMULATION / SA-MEM-MRAM-002-TRIANGLE-001

MRAM switching/read/retention triangle
MRAM Triangle

Replay STT/SOT labels, thermal barrier, and pulse width to compare write energy, switch probability, read margin, retention, and disturb risk.

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.

guided exploration
  • Read write probability and write energy together before ranking MRAM options.
  • Keep read margin, retention proxy, and disturb risk visible beside switching.
  • Use STT and SOT as mechanism labels, not commercial replacement claims.

RUN CARD

Conditions before conclusions.

This page replays saved MRAM surrogate rows and does not run micromagnetics, LLG, MTJ stack calibration, or product memory evaluation.

METHODS

How the number was made.

Methods are written for citation discipline: the extraction rule matters as much as the plotted value.

method

Drive current proxy scales with thermal barrier and mechanism label.

Keep this method attached when reusing the figure or metric.

method

Switch probability improves with pulse width while higher barriers add retention and write-cost pressure.

Keep this method attached when reusing the figure or metric.

method

The triangle score combines switching, read margin, retention, energy, and disturb risk to discourage one-metric claims.

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.

non-claim

No measured MTJ stack, stochastic thermal-noise LLG solve, endurance data, read-disturb measurement, or array implementation is included.

Carry this boundary into any derivative note, paper draft, or slide.

non-claim

No claim is made that MRAM replaces SRAM, DRAM, Flash, or HBM in a product hierarchy.

Carry this boundary into any derivative note, paper draft, or slide.

non-claim

Real MRAM study requires measured or published device data, array context, sense circuitry, write-error statistics, and retention/endurance conditions.

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.

evidence note

The dataset stores every STT/SOT, barrier, pulse, energy, probability, margin, retention, and disturb row.

evidence note

CSV export supports a memory-hierarchy comparison table without copying external course material.

SA-MEM-MRAM-002-TRIANGLE-001

evidence note

The memory domain now separates basic MRAM switching from a broader read/retention/disturb triangle.
