12:43PM EDT - Needing to have the right capability in the technololgy

12:44PM EDT - Have a good overall cost of ownership

12:44PM EDT - IoT is not a segment - it's a collection of applications spread across segments

12:45PM EDT - Mobile Segment, Compute Segment, Automotive Segment, Aerospace segment

12:45PM EDT - Low power in 40-130nm, Mid range in 22-28nm, High perf at 12-14nm

12:46PM EDT - Speed and memory types vary

12:46PM EDT - RF is important across all segments

12:46PM EDT - 17 levels of metal at 7nm

12:47PM EDT - The SoC Differentiator - to build value

12:47PM EDT - Some characteristics matter more depending on the IoT device

12:48PM EDT - Perf, Connectivity, Memory, Sensory, Storage, Battery, Security, Packaging, IP, Integration

12:50PM EDT - MRAM offers power and area savings

12:50PM EDT - Instant On for IoT is important

12:51PM EDT - If you put good MRAM on a mediocre platform, that's not going to win

12:51PM EDT - Need best in class compute and RF to get max benefit

12:52PM EDT - AI is a key part of the semiconductor 7% CAGR

12:52PM EDT - Break it up into two main areas : Datacenter (high-end training and inferencing)

12:53PM EDT - These use the high end processes, big chips, mostly ASICs

12:53PM EDT - The other side is mid-to-low end inferencing: IoT, Smartphones, Drones, ADAS

12:53PM EDT - classic foundry and ASIC, smaller die size

12:53PM EDT - balanced low power process

12:54PM EDT - IN high-end, big metal stacks requiremed, high density memory

12:55PM EDT - In edge devices, use FDX SoC platform, SoC design services

12:56PM EDT - Datacenter is usually based on thermal limits, low end is usually power limit driven

12:57PM EDT - How to win: IoT and ML

12:58PM EDT - AI/ML all about the datacenter - high performance, high speed IP etc

12:58PM EDT - IoT is all about the small chips and ultra low leakage

12:58PM EDT - Only high-density MRAM can really connect the two

12:59PM EDT - 22FDX is low power fully depleted SOI process

01:00PM EDT - Can run A53 at almost 2 GHz

01:00PM EDT - Lower dynamic and leakage

01:00PM EDT - 22FDX is king of power

01:00PM EDT - Uses back-biasing to help boost perf, or reduce back-bias to lower VTs and still run fast

01:01PM EDT - Overall 80% lower power

01:01PM EDT - Best in class mmWave perf

01:01PM EDT - eMRAM for NVM

01:01PM EDT - Increasing value prop by coupling eMRAM

01:02PM EDT - Ecosystem is already quite large, and growing

01:03PM EDT - Two versions of MRAM: -F for flash replacement, -S for SRAM replacement

01:04PM EDT - Differences in speed, endurance, data retention, operating temperature

01:05PM EDT - eMRAM-F is a cold storage technology, hence 15 year data retention

01:05PM EDT - eMRAM on 22FDX beats eFlash on 40nm

01:06PM EDT - Production of 22FDX eMRAM set for 1H 2019

01:07PM EDT - Status of 22FDX eMRAM

01:07PM EDT - Quarterly MPWs starting in Q1 2018

01:07PM EDT - Risk production by end of 2018

01:07PM EDT - JDV with Everspin in 2014

01:08PM EDT - Succeeded in each area

01:08PM EDT - 300 companies using production PDK

01:08PM EDT - 32Mb eFlash and 2Mb SRAM interfaces available for use

01:10PM EDT - Already announced $2b of design wins on 22FDX, most of which with eMRAM involved

01:10PM EDT - Next gen is 12FDX

01:10PM EDT - 7nm FinFET power efficiency with body bias, but still FDSOI planar process

01:11PM EDT - 40% fewer masks than 7nm DUV

01:12PM EDT - Four arms of technical challenges

01:12PM EDT - Never underestimate incumbents: eFlash scaling for example

01:13PM EDT - DRAM below 22nm is still in development - data integrity and corruption is a concern

01:13PM EDT - eDRAM has run out of steam

01:13PM EDT - SRAM Memory bandwidth is lagging behind CPU perf

01:13PM EDT - MRAM could help catch up

01:14PM EDT - IoT demand for lowest possible power memory solutions

01:14PM EDT - Non-technical challenges - cost of manufacturing ecoysystem, market acceptance

01:15PM EDT - making all the TAM accessible

01:15PM EDT - A lot of people want to go with the proven solution - hard to drive adoption without a compelling product

01:16PM EDT - MRAM is ready for GF customers

    So if I understand correctly, you can have MRAM on your SoC today,
    1. if you port your IP blocks to their 22nm process (but they have an A53 ready to use)
    2. you can choose between a high-density, long retention but slower variant to do 'storage things' and a lower-density, shorter retention variant to replace SRAM and DRAM tiers, if you can live with 5-10x slower access times vs. SRAM, but 2x areal density to 6T SRAM
    3. Costs you 4 extra layers, gains you non-volatility for the MRAM

    Sounds like an interesting niche.
