when looking at xpoint as a DDR memory, imagine you have a pair of high speed DDR4 memory at 4ghz… (
G.SKILL Ripjaws 4??)
say 32 or 64 gigs…
then you have the second set as Xpoint, and that is a terabyte
basically the xpoint is faster than a drive, but slower than DDR4
so basically you get to do all the fast work on the DDR4 and treat the Xpoint as a HUGE buffer for disk drives and large memory applications
right now you cant put a gigabyte database in memory…
but with xpoint, you could put 100gb in DDR memory allowing the DDR4 to access the XPoint resident database lots and lots faster than reading back and forth across the drive bus getting pieces of data and such to move to memory, here you just move from the large capacity xpoint bank to the super fast DDR4
similar memories are in the lcach or the processor
so think of that model applied to memory outside the processor.
thanks
