It should be known by now Samsung, Hynix, Micron, Toshiba all got their hands in the alternative memories like MRAM and RRAM. When DRAM and Flash are respectively replaced by these technologies, those who failed to pay for at least some research in these areas will be wiped out. Long-term consolidation catalyzed by investment in new technology.
Yes, it is GAME OVER for phase-change memory (PCM). Samsung realized last summer that its PCM has horrible power consumption in handsets, in addition to being slow in write, costly to make, with poor density and impossible to scale. Now the scamsters at IBM and Numonyx (now part of Micron) look real stupid!
