unless there has been a breakthrough that I haven't heard about (always 
possible) I seriously doubt that this is the case.

the alternate technologies that I have heard about are either _far_ less 
dense then DRAM (similar to static ram) or require erasing in blocks 
(similar to flash). niether one is appropriate for a large, flat 
addressed memory architecture as you list below.
