Considering that TLC NAND only has 300-500 write cycles the 1 million cycles they got with PCM is awesome. Not to mention the fact that it is 1000 times faster than NAND.It is good to see IBM coming up with TLC technology for this, it will enable NAND pricing for DRAM performance.
http://www.tomshardware.com/news/ibm-pcm-tlc-3d-xpoint,31811.htmlIBM announced that it has developed a method to store three bits of data per cell using Phase-Change Memory (PCM). Intel and Micron set the memory world afire with their 3D XPoint announcement, but they have not revealed the underpinnings of the technology, which many speculate is either ReRAM- or PCM-based. In either case, the IBM PCM products will line up as competitors for 3D XPoint, though the ability to store more data per cell could provide IBM with a cost and density advantage.
