Large flash chips are obtainable?

why do you think they made a small profit!?

This one is poor too :'( :o

we should help them, please buy from them or they would go bankrupt >:D

Their small  and tiny Operating income was about US$5.87 billion (2017) and US$18.34 billion (2018), we should probably help them be able to keep their business :-DD

They manufacture their own chips, a particularly difficult task with cutting edge technology. Also note that they also make general purpose DRAM, which is a lot more expensive per GB, and graphics DRAM, which is even more expensive. Those really help to pay back the huge investments of constantly upgrading fabs to stay competitive. The margins on Flash are thin, but they are able to more than make up for it with very high production volume.

ejeffrey:
Micron and sk hynix both manufacture memory chips.  It's not a super profitable business but thay is different than the companies that buy the chips and controllers and package them into off brand SSDs.

Only reason they turn a profit is by making massive volumes since the profit margins on flash are so thin. There is no way someone could just spin up a new flash memory fab out of nothing and turn a profit in small volumes. Quite a few even dropped out of flash memory manufacturing because it just was not worth it. Then the flash memory price crash happened recently where they groseley over estimated the demand for flash due to people not buying as many SSDs as they thought. But since the price of flash memory dropped like a brick so did prices of SSDs and so everyone did indeed start buying them and so the prices have stabilized again once this excess production volume was used up.

But at least flash has a bright future ahed of it. Hard drive manufacturers instead are feeling the pressure as flash is gradually closing the gap in price per GB.

If you have some cool ideas then by all means: start off buying expensive chips from digikey/mouser to make your prototypes.  If you have a product you want to manufacture in moderate volumes then you just start calling up bigger distributors.  You won't get the prices that the big players get when they have high volume ongoing contracts, but you should be able to do better than digikey.  If you find a niche market you might be able to sell some, although turning a profit or paying back reasonable development costs is going to be difficult in such an established and competitive market even if you come up with cool distinguishing features.


--- Quote --- have Ideas about making a 1TB SSD, so I need 64 chips of 16GB each (Serial interface like QSPI or Hyper flash), what are our options? do you have any idea?

AFAIK, most high capacity flash chips use parallel interfaces.  Certainly that is what is used in consumer SSDs.  I don't know if you can find QSPI or other "serial" flash chips in such large capacity.  Why is that important for your application?
