This is an obvious thing to do. I believe that we will see a lot of on-chip RAM some day when technology allows it. It may be SRAM. Small system-on-a-chip microcontrollers already have both SRAM and Flash on the chip. ForwardCom may be implemented in this fashion for some dedicated applications.


Actually, they've (Intel) already been studying the performance gains and power issues regarding logic+DRAM stacking quite since mid-2000's (see: "Die Stacking (3D) Microarchitecture" here www.cs.cmu.edu/afs/cs/Web/People/chensm/LBA_reading_group/papers/3D_stacking_Black06.pdf )
