The PCB with its NAND flash ICs and controller are covered by a sticker. We carefully peeled it off to have a closer look at the ICs. 

There you have it, this M.2 NGFF-2280 1TB SSD has just four MLC NAND ICs, amazing stuff and yes, the biggest benefit of the ability to stack memory cells vertically.

The backside is clean/clear from anything, you will not find any components there. 

 
So this is the new Polaris controller, a five-core, eight-channel chip. This updated controller replaces the UBX controller used in the popular PM951/950 series. 
  

And to your lower left, one of the four NAND ICs. 48-layer (3D) Vertical NAND. The 512GB model will get a 512MB DRAM cache, the 1TB version a 1 GB cache and the 2TB version a 2GB DRAM cache. The interesting thing is that we cannot physically find a DRAM cache chip on the PCB. Logic dictates that the DRAM cache has been moved inside the NAND ICs which would explain the linear increase in cache. We are still checking this though.
