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.
