Huawei pitches an architecture-first scaling law to skirt EUV denial, the memory supercycle prices sub-$100 phones out of emerging markets, and Google's AI search box draws a reported migration to rivals.
Huawei’s road around the EUV wall
At ISCAS 2026 in Shanghai, Huawei’s semiconductor chief He Tingbo presented a scaling methodology that reframes chip progress around the RC time constant τ, the resistance-capacitance product of devices and interconnects, rather than geometric node shrink. The pitch, branded the “Tau Scaling Law,” targets τ across device, circuit, chip, and system levels. Its headline technique, “LogicFolding,” claims to shorten critical-path wiring to cut signal delay and raise effective transistor density; at the system level, a “UnifiedBus” interconnect with unified memory addressing stitches chips into what Huawei calls “SuperPoDs.”
The pitch answers export controls. Barred from TSMC and ASML’s EUV scanners, Huawei depends on SMIC, whose production process tops out at 7nm finFET built on 193nm DUV multi-patterning. Huawei says the τ path reaches transistor density equivalent to a 1.4nm node by 2031: a density-equivalence claim, not literal 1.4nm fabrication. It says 381 chips have already been designed this way over six years, and that Fall 2026 Kirin parts will be the first to ship LogicFolding. None of it carries third-party benchmarks or disclosed methodology; the keynote closed with an appeal to “openness and collaboration.”
The memory supercycle’s downstream bill
A weekly recap from Asia Tech Review argues the AI industry’s appetite for high-bandwidth memory is killing the sub-$100 smartphone. With memory makers at capacity and booked years ahead, commodity DRAM and NAND have grown scarce and costly; phones that sold for $50 now run about $120, and price-sensitive buyers stop upgrading. Citing a feature by David Oks, it reports Transsion’s 2025 net profit down 54% with a 40% cut to its shipment target, plus reductions at Oppo (over 20%) and Vivo (about 15%), and a 19% year-on-year drop in Xiaomi’s Q1 2026 shipments. The recap frames Apple as a beneficiary: it paid Samsung a memory premium, and Indonesia’s premium segment grew 30% even as total shipments fell 9%. The figures are Oks’ reporting, not independently checked.
Google’s search box and the open web
Michael Tsai’s link-blog roundup collects reaction to Google’s I/O overhaul of Search around an AI-powered “intelligent search box”: interactive AI experiences, dispatchable “information agents,” and user-built mini apps, which Google calls the biggest change to Search in more than 25 years. Google says AI Mode is not the default, but Tsai reads its nudge toward follow-up questions over outbound links as a de facto move against third-party sites, the “Google Zero” scenario named by The Verge’s Nilay Patel. He aggregates unverified backlash metrics: DuckDuckGo’s AI-free search reportedly up 22.7% week-on-week, and its US app installs up 18.1% on average, with commenters citing Kagi, Ecosia, and udm14 workarounds. It is opinion aggregation, and the growth figures are percentage spikes without baselines.
What to watch today
- Fall 2026: the first Kirin chips Huawei says will ship with LogicFolding, the first test of τ-scaling claims against real silicon.
- Q2 2026 smartphone shipment numbers from Transsion, Xiaomi, and Oppo, for whether memory pricing keeps cutting low-end volumes.
- Independent search-share data, to see whether DuckDuckGo and Kagi gains hold past the I/O news spike.
