Huawei is on its journey to develop in-house or rely on Chinese national tech solutions after the United States cut crucial access. Meanwhile, the latest Huawei flagship phones still depend partly on Samsung-made memory solutions.

In a Kirin 9030 and 9030 Pro teardown, SemiAnalysis (via SemiconductorsX) discovered a mix of Samsung and CXMT memory chips, powering the Huawei Mate 80 series flagship phones.

The Pro variant carries 12 GB of Samsung DRAM, two stacks of four dies each, identified as the K4L2E165YD. That’s LPDDR5X-9600 built on Samsung’s 1a node, the fourth generation of its 10nm-class DRAM family after 1x, 1y, and 1z.

Irony doesn’t get much richer than this. Samsung’s 1a has shipped in volume since 2022, which means Huawei is buying current, competitive memory from the company whose country’s government is actively sanctioning them.

SemiAnalysis report pointed out:

China is not closing the gap with Intel, Samsung and TSMC. The teardown shows the opposite in several places: no EUV, no backside power, higher process complexity, and visible trade-offs.

Units surfaced with two different memory packages, depending on who built them, Samsung or China’s CXMT. The CXMT 16GB package, marked CXDD7JEDM and assembled in week 45 of 2025, is stacked the same way.

CXMT is closing the distance, but Huawei still needs Samsung to fill the top of its own lineup.
