Chinese startup hires chip godfather and TSMC vet to break into DRAM biz

They're putting a crew together, and Beijing's tossed in $750m to get things started


A Chinese state-backed startup has hired legendary Japanese chip exec Yukio Sakamoto as part of a strategy to launch a local DRAM industry.

Chinese press last week reported that Sakamoto has joined an outfit named SwaySure, also known as Shenzhen Sheng Weixu Technology Company or Sheng Weixu for brevity.

Sakamoto's last gig was as senior vice president of Chinese company Tsinghua Unigroup, where he was hired to build up a 100-employee team in Japan with the aim of making DRAM products in Chongqing, China. That effort reportedly faced challenges along the way – some related to US sanctions, others from recruitment.

The company scrapped major memory projects in two cities and was forced into bankruptcy last year, before Beijing arranged a bailout.

While that venture failed, 75-year-old Sakamoto's CV remains hard to match. He was once president at Japan's Elpida Memory – a major Apple supplier with the capacity to produce over 185,000 300mm wafers per month. Micron bought the company in 2013.

Sakamoto's new employer, which he claims will be his last, was established in March with ¥5 billion ($745 million) of registered capital and 100 percent controlled by Shenzhen state-owned assets, according to Chinese state media.

Its main products are listed as general-purpose DRAM chips for datacenters and smartphones, developed by teams in Japan and China.

Sakamoto will join Taiwan Semiconductor Manufacturing Co (TSMC) veteran Liu Xiaoqiang, said Chinese state media outlet Global Times. Although Liu left TSMC three years ago, the employment choice raises eyebrows given China's yearning for Taiwanese talent, complete with accusations of poaching and speculation of aggressive methods to obtain it.

Beijing has been extremely eager to achieve tech self-sufficiency amid US sanctions in an already critical supply chain environment. In October 2020, China set a goal of growing all its own tech at home by 2035.

Unfortunately for the Middle Kingdom, that goal seems more elusive by the day. Analyst house IC Insights predicted that by 2026, China will only produce 20 percent of the chips it uses.

Previous attempts to create a steady domestic DRAM stream in China have been thwarted by pesky things like IP laws. In addition to Tsinghua's failure to thrive, state-owned Fujian Jinhua Integrated Circuit Company was indicted on industrial espionage charges in the US and banned from importing semiconductor equipment and materials from the States.

Instead, the market remains dominated by the likes of Korea's Samsung and SK hynix, plus US company Micron. According to IC Insights [PDF], the trio held 94 percent of global DRAM market share in 2021. ®

  • DRAM prices to drop 3-8% due to Ukraine war, inflation
    Wait, we’ll explain

    As the world continues to grapple with unrelenting inflation for many products and services, the trend of rising prices is expected to have the opposite impact on memory chips for PCs, servers, smartphones, graphics processors, and other devices.

    Taiwanese research firm TrendForce said Monday that DRAM pricing for commercial buyers is forecast to drop around three to eight percent across those markets in the third quarter compared to the previous three months. Even prices for DDR5 modules in the PC market could drop as much as five percent from July to September.

    This could result in DRAM buyers, such as system vendors and distributors, reducing prices for end users if they hope to stimulate demand in markets like PC and smartphones where sales have waned. We suppose they could try to profit on the decreased memory prices, but with many people tightening their budgets, we hope this won't be the case.

  • China is trolling rare-earth miners online and the Pentagon isn't happy
    Beijing-linked Dragonbridge flames biz building Texas plant for Uncle Sam

    The US Department of Defense said it's investigating Chinese disinformation campaigns against rare earth mining and processing companies — including one targeting Lynas Rare Earths, which has a $30 million contract with the Pentagon to build a plant in Texas.

    Earlier today, Mandiant published research that analyzed a Beijing-linked influence operation, dubbed Dragonbridge, that used thousands of fake accounts across dozens of social media platforms, including Facebook, TikTok and Twitter, to spread misinformation about rare earth companies seeking to expand production in the US to the detriment of China, which wants to maintain its global dominance in that industry. 

    "The Department of Defense is aware of the recent disinformation campaign, first reported by Mandiant, against Lynas Rare Earth Ltd., a rare earth element firm seeking to establish production capacity in the United States and partner nations, as well as other rare earth mining companies," according to a statement by Uncle Sam. "The department has engaged the relevant interagency stakeholders and partner nations to assist in reviewing the matter.

  • ZTE intros 'cloud laptop' that draws just five watts of power
    The catch: It hooks up to desktop-as-a-service and runs Android – so while it looks like a laptop ...

    Chinese telecom equipment maker ZTE has announced what it claims is the first "cloud laptop" – an Android-powered device that the consumes just five watts and links to its cloud desktop-as-a-service.

    Announced this week at the partially state-owned company's 2022 Cloud Network Ecosystem Summit, the machine – model W600D – measures 325mm × 215mm × 14 mm, weighs 1.1kg and includes a 14-inch HD display, full-size keyboard, HD camera, and Bluetooth and Wi-Fi connectivity. An unspecified eight-core processors drives it, and a 40.42 watt-hour battery is claimed to last for eight hours.

    It seems the primary purpose of this thing is to access a cloud-hosted remote desktop in which you do all or most of your work. ZTE claimed its home-grown RAP protocol ensures these remote desktops will be usable even on connections of a mere 128Kbit/sec, or with latency of 300ms and packet loss of six percent. That's quite a brag.
