Intel and Micron are introducing a new type of memory that will be a major breakthrough in memory process technology.
3D Xpoint (pronounced cross point) is up to 1,000 times faster and will be more durable than the typical flash storage ( the standard for mobile devices and solid state drives).
The memory allows of persisting of data (non-volatile) in a high capacity, high performance solution.
Because the structure of the memory is more dense, it will be will allow for more rapid access closer to the processor.
This has the potential to replace FLASH, SSD and RAM all with this new type of memory.
What this means: Imagine a computer that comes with 5TB of this stuff that is both RAM and STORAGE with no differentiation between the two and now speed drops transferring things. Games would never “load” in the traditional sense again as “loading” is moving data from storage to the main system memory so the CPU can manipulate it.

Initial sizes will be targeted at 128 gb and will likely be designed for server side use, but as time and commoditization goes we should see this in consumer devices in the not-to-distant future.
