A "universal" memory technology has been the holy grail for decades: fast as SRAM, density and non-volatility of Flash, and cost of DRAM. There are various technologies that combine at least some of these characteristics: Magneto-resistive (MRAM), ferroelectric (FRAM), phase-change memory (PCM), programmable metalization cell (PMC) and resistive (RRAM). Whether any of these will be commercially viable is still unknown.
I can easily imagine that flash will displace hard drives in most laptops and desktops, but server farms are still going to need massive amounts of cheap storage. Rotating media still has a huge lead in $/bit (100X) so I don't think it will be displaced in there any time soon.
