Yes, the linked one is the first PDF I've found. I know the commercial NANDs found in newest SSD may not be available, because it's probably that the SSD is using a custom chip design. Perhaps the chip is listed somewhere in a website, but unavailable for purchase (for mere mortals like us or those doing an open source SSD). In any case, those chips won't be available for an open source SSD.

Soon I should put hands on a design with a 2Tb Micron NAND from 2014 (MT29F256G08something). The PDF is behind a simple user registration.
