MIcron announced it was ceasing further development of Optane technology. The company was spending $400 million annually on the technology but the ROI is not adequate for further development. In 2018, Micron purchased Intel’s stake in 3D XPoint for $1.5 billion. In line with this new strategic focus, Micron is engaged in discussions for the sale of its Lehi, Utah, fab currently dedicated to 3D XPoint production. The company aims to reach a sale agreement within calendar year 2021.

Several years ago Intel and Micron worked together to develop the technology. The competition from NAND flash has squeezed Optane out of most hyperscale designs. Optane was not able to scale as rapidly as SSD which adopted the stacked design to increase capacity.

Micron is a large manufacturer of NAND, NOR and RAM which is the focus of the company now. Crucial is the public brand that Micron uses with domestic retailers. Micron branded memory is also seen in the OEM market,
