Is not that DRAM is dead, it is simply Intel will be putting Memory Cube, or Stacked DRAM or TSV Memory what ever you wanted to call it in the CPU die itself. Stacked DRAM provides up to 1Tbit/s of bandwidth. More then the current Graphics Card has.

As SSD gets faster every year, we need less memory to cache off the content where we used to need for performance reason from a HDD. With Windows 8 i have been using less then 4GB of Ram including standby, with Virtual Memory turned off. ( I have 16GB of Memory ). The future CPU die could easily stack 4 1Gbit DRAM with 8 layers of up to 4GB of Memory. Coupled with a SSD that goes up to 2GB/s transfer.
