    You doubt what? That purchase was publicly announced by AMD, the chip is being produced in China under that agreement, and no US government agencies objected it.

    And it is not patent, it is license. AMD did not sell the ownership of the license. AMD sold a right of usage of the license, and AMD apparently has the right to do so, since Intel never sued AMD in any US court.

    Don't pretend that you know things more than US government, Intel and AMD.

    now I've read about related CPUs; it's dated 10 Jul 2018, kinda cool:

    I think I'm a clone now: Chinese AMD Epyc-like server chips appear in China. What gives?

    I recall reading a NY Times article back in November that was heavily critical of AMD's joint venture in China:

    The quotes used in the article express shock and indignation that the agreement wasn't blocked by US regulators. It was simply unbearable to them that China managed to obtain technology fairly and legally - even though technically AMD's safeguards mean that China would be unable to reverse-engineer the Zen architecture.

    It happened few days ago, the cold atomic clock has been run aboard Tiangong-2 for 15 months.

    The tech details published.
    In-orbit operation of an atomic clock based on laser-cooled 87Rb atoms

    In my imagination, before the size is brought down it can be used by BDS by transmitting the sync signals via the GEO and IGSO BDS sattelites to all MEOs. In the long run, when the size is small enought, the clock can be moved to the next generation GEO and IGSO BDS sattelites or even MEOs. The outcome is the multifold increase of BDS accuracy, if today is decimeters, it will be cetemeters or millimeters.

    YMTC to Detail 3D NAND Chips
    Xtacking said to enable DDR4 speeds


    SAN JOSE, Calif. — Yangtze Memory Technologies Co., Ltd. (YMTC) will unveil next week its latest 3D NAND chips. The talk by chief executive Simon Yang at the Flash Memory Summit here will mark the first public discussion of an effort from China to produce leading-edge memory chips.

    YTMC will describe what it calls Xtacking as an approach to 3D NAND that delivers a “speed-up to DRAM DDR4 while delivering industry-leading bit density, marking a quantum leap for the NAND market.” Xtacking “enables parallel processing of the NAND array and periphery … a modular approach [that will] shorten the time-to-market for new generations of 3D NAND and open the possibility for customized NAND flash products,” according to a press statement.

    The company, described as the pride of China, has long been seen as one of the country’s most likely candidates to deliver a commercially viable mainstream memory chip. It was founded in 2016 with a whopping $24 billion in funding, leveraging the 12-inch fabs of China’s XMC in Wuhan.

    YMTC announced a 32-layer 3D NAND chip last year and said that it would ship this year a 48-layer version. In February, a Wall Street analyst said that YMTC’s yields on its 32-layer NAND chips were still very low, suggesting that a 48-layer part could still be many months from general availability.

    If YMTC’s target remains the same, it will be one or two steps behind larger rivals. Intel, Micron, Samsung, and Toshiba/WD have announced or are shipping 96-layer, 4-bit-per-cell devices. Samsung said that its chips have DDR4-like speeds at 1.4 Gbits/second.

    The YMTC news comes at a time of heightened trade tensions between the U.S. and China, where semiconductors have been a particular flash point.

    Industry trade groups have long lobbied the U.S. government to help set a level playing field in China. The China government is investing heavily in chips and requiring foreign firms to transfer their technology in exchange for market access, they claim. However, they protested the Trump administration’s recent tariffs as an ineffective and even harmful approach.

    YMTC said that its Xtacking chips will be used in UFS as well as client and enterprise solid-state drives for use in smartphones, PCs, and data centers. The company claims that it has “help from customers, industry partners, and standard bodies [to enable] a whole new chapter in high-performance NAND solutions.”

    Ironically, Samsung, which was the first company to announce commercial 3D NAND chips at the Flash Memory Summit, is not participating in the event this year. The gap leaves YMTC an opening to be the talk of the show at which all the other major flash vendors are participating.
