As was already mentioned it may actually be. Another factor is that 16M
flash chips were available only some time later than 8M flash chips.
And finally I would say that sourcing can be a significant factor;
It can be a lot easier to source 1x each of two parts with different
parameters, than 2x of a single part with particular parameters.
