Hi Technusatsu; Re Carl's posts on pin costs... I must have posted a dozen long, detailed posts, with internet links on this subject.

The IBM example of a 5000 pin package is an example of a leading edge technology, a technology that was impossible until recently. But that is only one of at least a dozen links I gave about pin costs.

It is very clear that pin costs have dropped over the years, not as fast as Moore's law for transistors, but nevertheless consistently. Standard DRAM used to be x1 width, now it is more like x8 and x16 are available at the same price.

But the really important thing about pins is that the new bump technology eliminates the need to bond each pad individually. It is quite obvious that this improvement in automation is going to drop the cost of pins to a very small fraction of the current cost.
