## basic commercial advantages ... materials dependent

- pros

[faster switching than SRAM, but slower than charge-based DRAM?](https://www.forbes.com/sites/karlfreund/2021/03/10/ibm-nears-breakthrough-in-new--memory-class/?sh=6cdfc9dff6d5)

**more energy-efficient than DRAM?**

**"collective switch" of stt-mram has very different behaviour** than a single-electron-based physics of non-magnetic Tunneling Junctions of DRAM/SRAM - what is better and what is worse?

Write power is low according to [what work/references (according to Table on page 7 here)?](https://knowen-production.s3.amazonaws.com/uploads/attachment/file/5052/v%2B1-2%2BEmbedded%2BSTT-MRAM-based%2Bchip%2Bfor%2Bone-cycle%2Bneural%2Bnetwork%2Bperformance.pdf).... errors on writing are widely discussed, pls find a reference too (MT)

- cons


still more expensive than DRAM... so far?
