良率决定盈利！全球三大存储芯片厂商正式开启HBM4良率竞争_我的网站

A |     TikTok is now facing multiple lawsuits after at least seven children under the age of 15 died while attempting the “blackout challenge”, alleges a suit filed against TikTok in June. The challenge encourages social media users to choke themselves with belts, purse strings, or similar items until they pass out.,The parents of Arriani Jaileen Arroyo gave their daughter a smartphone at the age of 7, she then downloaded TikTok and became “addicted” to the platform, her parents said. She started trying internet challenges but because those challenges involved foods and beverages Arriani’s parents thought little of them.,Then on February 26, 2021 Arriani was found with a leash tied around her neck, inspired by the TikTok choking challenge; she died that same day.,Other children across the globe—not just in America—have died from trying the “blackout challenge”: a 10 year-old in Italy, a 14 year-old in Australia, as well as a 12 year-old in Colorado, a 12 year-old in Oklahoma, and a 10 year-old in Pennsylvania. Lalani Erika Renee Walton, 8, also died while attempting the blackout challenge.,Family members of Lalani and Arriani are now suing TikTok. They are being represented by the Social Media Victims Law Center, a law firm that “works to hold social media companies legally accountable for the harm they inflict on vulnerable users”, according to their website. This is the second lawsuit the social media app has faced following a fatal incident involving the blackout challenge.,“TikTok has specifically curated and determined that these Blackout Challenge videos — videos featuring users who purposefully strangulate themselves until losing consciousness — are appropriate and fitting for small children,” the lawsuit reads.,The company argues that the “blackout challenge” has been around for years. Between 1995 and 2007 CDC discovered 82 deaths caused by “the choking game” which saw kids aged six to 19 die.,"This disturbing ‘challenge,’ which people seem to learn about from sources other than TikTok, long predates our platform and has never been a TikTok trend,” TikTok said in a statement. “We remain vigilant in our commitment to user safety and would immediately remove related content if found. Our deepest sympathies go out to the family for their tragic loss.”,In 2019 TikTok had to pay $5.7 million in settlement charges after violating a children’s privacy law, said the Federal Trade Commission who filed the charges. The app “illegally collected personal information from children” after it failed to require parents’ permission before signing up for the app. The Children’s Online Privacy Protection Act (COPPA) requires websites to ask children under the age of 13 to get their parents’ permission before sharing personal information online.。    7月22日，据财闻海外资讯，三星电子、SK海力士（SKHY.US）与美光科技（MU.US）三大存储芯片厂商全面展开HBM4良率竞争。作为第六代高带宽内存，HBM4将应用于英伟达（NVDA.US）下半年推出的Vera Rubin等AI加速芯片，成为下半年企业业绩关键支撑。         三星已率先实现HBM4规模化量产，业内预估其良率接近70%，得益于1C工艺DRAM（年初良率稳定超80%）的持续带动，良率管控能力显著提升。         SK海力士虽未公布精确良率，但行业判断其已进入稳定区间。为巩固超半HBM市场份额，其正洽谈引进新生产设备，以优化工艺并扩大产能。         美光因产能基础相对薄弱，正加速推进良率爬坡与大规模设备投资，同步提升产出能力。         良率（合格芯片占比）直接决定交付量与盈利空间，是厂商攻坚核心。尽管此前通用DRAM短期利润反超，但其涨价空间已趋缓（一季度近翻倍、二季度30%–50%、三季度0%–20%），而HBM需求持续扩张、高毛利优势将重归主导。         业内人士表示：“三星抢先落地 HBM4 量产，良率提升带来的供货增量、利润增长已经在二季度财报中充分体现；下半年该趋势将延续，三大存储企业的良率竞争会进一步白热化。
