What does the leak actually claim?
The report says Huawei, DRAM maker Swaysure and Chinese government entities have formed a partnership to set up a 12-inch memory fabrication plant. The details come from a single account on X, @SemiconductorsX, and were picked up by Wccftech, which rates the story as merely “plausible” at 55% confidence. That framing matters: nothing here is confirmed by Huawei, Swaysure or Chinese authorities.
According to the leak, the plant would begin with mass production of 28nm DRAM at a capacity of around 140,000 wafers per month. The same report claims a former TSMC director has been hired as CEO and an ex-Elpida executive brought in as a strategist. Huawei Central and SDxCentral both frame the reported fab as a response to memory shortages and US export controls that limit Huawei’s access to foreign suppliers.
Why would Huawei build its own DRAM plant?
The strategic logic is straightforward, even if the fab remains a rumour. Samsung, SK hynix and Micron together hold around 95% of global DRAM supply, which leaves any company outside that circle dangerously exposed — and Huawei, cut off from much of the foreign supply chain by sanctions, is more exposed than most. Building domestic memory capacity would give it something to fall back on if shipments from the big three were ever blocked.
The shortage itself is real and worsening. Rival memory makers have warned that the crunch could deepen through the back half of the decade, which is precisely the environment that makes vertical integration attractive rather than reckless. For Huawei, rising DRAM costs feed directly into smartphone production expenses, and pricier devices are harder to sell — so securing its own supply, ideally at lower prices, is a defensive move as much as an offensive one.
How plausible is it, really?
Plausible enough to take seriously, even without confirmation, because Huawei has already been quietly assembling exactly this kind of capacity. Reporting from The Elec, relayed by Huawei Central and Digitimes, describes Huawei controlling — directly or through affiliates — around 11 fabs spanning memory, logic and foundry work, in what looks like a shift toward a full integrated device manufacturer model. A Bloomberg-sourced account carried via Yahoo goes further, detailing a covert network of plants built to sidestep US restrictions, including a Swaysure facility aimed at memory for automotive, consumer electronics and wearables.
This mirrors Huawei’s broader self-reliance push, from its longer-term plan to reach cutting-edge nodes despite sanctions to reported work on high-bandwidth memory with local partners. The caveat stands: the specific Shenzhen DRAM fab, its capacity figure and its named executives all trace back to one leak. Where the supporting picture is solid, the fine detail of this particular plant is not.
