"We must break ourselves of our addiction to RAM."

"More and more RAM is not the answer."

"The United States, with just 5% of the worlds population, uses 60% of the worlds RAM."

"Instead of piling on more and more RAM, a better solution might be to just take the blue pill."

There was a session at hot Chips 2012 on Stacking ....one way was to use Interposers....so I include this:

BGA with a interposer between the integrated circuit die to ball grid array

Pentium II: example of an interposer, integrated circuit die to ball grid array chip carrier

An interposer is an electrical interface routing between one socket or connection to another. The purpose of an interposer is to spread a connection to a wider pitch or to reroute a connection to a different connection.^[1]

Interposer comes from the Latin, interpōnere, meaning 'to put up between.' ^[2]

A common example of an interposer is an integrated circuit die to BGA, such as in the Pentium II. This is done through various substrates, both rigid and flexible, most commonly FR4 for rigid, and polyimide for flexible.^[1]

Another example of an interposer would be the adapter used to allow a SATA drive to work in a SAS environment. An interposer would allow a SATA drive to plug into a SAS backplane.
