'16TB' of silicon at current rates is not a few cents, not even close.

'16TB' of silicon at current rates is not a few cents, not even close.
- 6nf 8y agoSure it is, where do you buy your silicon wafers?
- Thetawaves 8y ago64L 3D NAND flash is about 4.40Gb/mm^2. 16TB = 131,072Gb. 29,789mm^2. 70,686mm^2/std 300mm wafer. Roughly 2 dies/wafer, with exceptional packing, and don't account for defect rates. Average $0.74/in^2 109.56in^2/std 300mm wafer 81$/std 300mm wafer roughly 40$ in materials BEFORE you even start talking about the processes to build up 64 layers, and everything else.
