s NV and SADP technology. In 2011 IM Flash moved to a 20 nm process– which was the smallest NAND flash technology at the time. On July 16, 2018, Micron and Intel announced that they would cease joint development of 3D XPoint after the 2nd generation technology is finalized, which is expected to be completed in the first half of 2019. Technology development beyond the 2nd generation will be pursued independently by the two companies in order to optimize the technology for their respective product and business needs. The two companies will continue to manufacture memory based on 3D XPoint technology at the Intel-Micron Flash Technologies (IMFT) facility in Lehi, Utah. On October 18, 2018, Micron announced their intention to exercise its right to call the remaining interest in the parties' joint venture, IM Flash Technologies, LLC. Micron is to exercise the call option starting January 1, 2019 and the timeline to close the transaction is between six and twelve months after the date Micron exercises the call. At the time of close, Micron expects to pay approximately $1.5 billion in cash for the transaction, dissolving Intel's non-controlling interest in IM Flash as well as IM Flash member debt, which was approximately $1 billion as of Aug. 30, 2018. On October 31, 2019, Micron closed the acquisition of all of Intel's stake in IM Flash Technologies. IM Flash Technologies is now legally known as Micron Technology Utah, LLC. On October 22, 2021,
