Let's say I had a very large static dataset that I'd like to distribute via solid state memory to a lot of people. Let's say it's on the order of terabytes. What would be the densest type of storage I could use?
I read somewhere that in Intel's 14nm process they can fit ~37 million transistors on a square millimeter which would mean that about 400 MB could be stored on a square centimeter. This assumes one transistor per bit, which I assume is as good as you can get for ROM. (is this a good assumption?)
But then I notice that you can buy a 256 GB microSD card which is smaller than my hypothetical ROM. How the hell is the flash so dense and would it be possible to make a ROM that dense (or denser)?
