Possible to identify this Flash chip?

[john5677]

Hello. I took apart a new SSD and the flash chips are labeled 4xb2d on the first line and nw674 on the second line. There is a capital M with a halo around it which I assume is the Micron logo. Is it possible to find more information about this chip (TLC or MLC)? Or is this chip undocumented for some reason? Thanks.

if it's indeed micron, you can go look at the parts catalog on their website...
