NeoTeo, CXMT의 AI 메모리 제품인 HBM3E 생산 계획을 발표했다.

Reuters reported on October 28, 2026, that CXMT planned limited production of HBM3E memory for AI processors within the following two months. The report also said, citing anonymous sources, that CXMT had sent samples to Chinese AI-chip designers. The stated target is limited production, not a reported commercial supply volume.

**What the reported yield estimate means**

The same account put CXMT's HBM3E manufacturing yield at 20%–30%. Yield is the share of manufactured units that meet the relevant specifications. In plain terms, that estimate works out to about two or three qualifying units out of every ten. It is not a measured count from a disclosed production run.

The account also placed SK hynix's yield at about 70%. These are separate reported estimates, not a matched comparison. Yield measures manufacturing output that meets specifications. It does not describe memory speed or capacity.

**What the sample report says about performance**

One source characterized the reported CXMT samples as closer in performance to SK hynix HBM3 than to SK hynix HBM3E. That is a qualitative comparison of sample performance, separate from the manufacturing-yield estimates. The reported recipients were Chinese AI-chip designers.

HBM, or high-bandwidth memory, uses vertically stacked, interconnected DRAM dies positioned near a processor. The HBM3E label in the report identifies the memory generation CXMT was said to be targeting, not a complete product specification.

**How the October plan fits earlier reporting**

FomoEra said its August coverage had referred to The Information reporting small quantities of CXMT HBM3E. The October timetable does not describe a first-ever production start, and the relationship between the earlier account and the later limited-production target remains unresolved.

**Why a production target is not a supply forecast**

A new DRAM fab can take 18 months or more to build and start up, according to an IEEE Spectrum analysis published February 10, 2026. A TEN Brief analysis published August 2, 2026, describes a typical one-to-two-year lag between capital spending and memory supply. Those industry timelines put capacity plans in context. They do not set a schedule or price effect for CXMT's reported HBM3E production target.
