MEMORY / DEVICE / INTEGRATION

Emerging device, memory & integration

Read evidence maturity as five separate questions. A mechanism link does not close measurement, reliability, or product readiness.

EVIDENCE ANATOMY

Five questions. No aggregate maturity score.

Each cell preserves its own state, source gate, evidence class, and replacement requirement. The dimensions cannot compensate for one another.

01

Mechanism

What physical effect is proposed, and which assumptions connect it to the observable?

Discovery can begin here
02

Integration

What process sequence, interface, contact, thermal path, and compatibility constraint must coexist?

Context is not completion
03

Measurement

Which metric contract, method, uncertainty, sample basis, and reproducibility state support the result?

GAP in V138
04

Reliability

Which stress, time, temperature, cycling, recovery, and failure-mode evidence has been reviewed?

Separate from function
05

Product readiness

Which qualification, manufacturability, cost, supply, and owner decision gates have actually closed?

HELD in V138

V138 TOPIC SET

Visibility does not mean endorsement.

The atlas keeps promising topics visible for structured review while refusing technology ranking, commercial recommendation, recipes, and unsupported performance transfer.

FeFET / HZOHeld for primary-source review
IGZO memoryDiscovery context only

READING ORDER

Move from a named question to an explicit stop.

  1. 01
    Name the topic

    Keep the device or integration subject explicit; do not compare labels that hide different objects.

  2. 02
    Choose one dimension

    Ask a mechanism question, integration question, measurement question, reliability question, or readiness question.

  3. 03
    Read the state

    DISCOVERY_LINKED, STRUCTURAL_CONTEXT, GAP, and HELD carry different meanings and never become a score.

  4. 04
    Trace the source gate

    A deduplicated URL is discovery metadata until the primary body, rights, claim edge, and metric contract are reviewed.

  5. 05
    Stop visibly

    Missing evidence remains missing. Held candidates, contradictions, and empty replacement slots stay on screen.

PUBLIC BOUNDARY

Discovery is useful when its limits travel with it.

V138 carries deduplicated link metadata and existing deterministic teaching context. It copies no publication figure or body, validates no claim-source edge, fills no owned replacement slot, and issues no qualification, disposition, tapeout, signoff, product, or investment decision.
