Ask HN: What are some good resources to learn about NVM?

I was skimming through conference papers like ATC, OSDI, ... and there are many papers to build databases on top of NVM.

Unfortunately I'm failing to find a useful resource to learn the structure of NVM (in particular the byte addressable interface). There are a couple of NVM libraries out there with in-cohesive documentation.

Traditional file systems on top of NVM using block-level interface is not an issue. Bare in mind that I'm a CS student with minimal electrical engineering knowledge. Also, I have a fairly good knowledge of SSD internal design (FTL, ...)
