> That is true. However, those less performant chips, due to the way NAND storage functions, could easily be used in place of the newer chips.
I was mostly thinking of serial flash chips there, which use a very different interface from plain NAND; they have their own little controller built into them. They are used in relatively big numbers for firmware etc. Even if they had the same interface, there is still a huge gap between a 128 MBit chip and the densities you find in PC storage, where we now have 512 GBit chips.
Samsung & Co. might make them too, but you mostly see other semicons badged on them.
