Back in 2015, Micron and Intel announced the development of a new type of memory. Dubbed 3D XPoint (Crosspoint), the new type of memory offered endurance levels NAND flash couldn’t match and theoretically higher performance. Intel marketed its brand as Optane while Micron intended to launch its own QuantX products. Micron never actually shipped hardware to the wider public, and Intel has recently scaled back its own Optane efforts to focus on the enterprise.
