    3D XPoint’s “PMem” speed is in microseconds, magnitudes slower than 4DS, retention is at 3 months with Endurance comparable to flash at 10^5, again magnitudes lower than 4DS. Furthermore, manufacturing cost were too high.

    Micron and Intel failed to achieve true SCM characteristics and decided to stop development and classify XPoint as EOS.

    Comparing 4DS Memory Technology with XPoint is like comparing a Porsche GT3 RS with a Datsun 120Y.
