CXMT Officially Starts Mass Production of LPDDR6 Memory
CXMT has achieved the remarkable feat of officially beginning high-volume manufacturing of LPDDR6 memory. This positions CXMT's LPDDR6 memory modules as some of the first in the industry, with South Korean memory makers on a similar timeline for volume production of this next-generation technology. Reportedly, Xiaomi is the first customer for CXMT's domestic LPDDR6 memory, set to feature in the upcoming Xiaomi 18 Fold smartphone. Since the Xiaomi 18 Fold is scheduled to launch in September, CXMT's LPDDR6 memory will need to be delivered before the end of the month, indicating that customer shipments are already underway. This news follows recent reports that CXMT is conducting risk production of LPDDR6, suggesting a very high yield in production.
CXMT's LPDDR6 memory will operate at speeds of up to 12.8 Gbps, with the base speed of LPDDR6 being 10.7 Gbps. LPDDR6 builds on where LPDDR5X left off, which could reach speeds of up to 10.7 Gbps when highly overclocked. However, the new standard aims for significantly higher speeds, with the first generation of LPDDR6 from CXMT's fabs reaching 12.8 Gbps. Additionally, CXMT is producing these chips with a 16 Gb capacity, equivalent to 2 GB, and the memory IC is housed in a package-on-package (POP) casing, featuring about 1,295 pins in a ball grid array.
Update, 14:55 UTC, September 7th : CXMT's official website confirmed mass production, with Alibaba Cloud, ByteDance, Tencent, Lenovo, Transsion, Honor, Vivo, and Oppo as customers.
We also learned that SK hynix is close to mass production. The South Korean memory giant announced earlier that its LPDDR6 memory modules would feature a 16 Gb capacity on the sixth-generation 10 nm node, known as 1c, running at up to 14.4 Gbps. Although these SK hynix modules might operate faster, all these speeds fall within JEDEC's official specification for the LPDDR6 standard. We can expect even faster memory chips as technology and manufacturing capabilities continue to advance.

So my point is that DDR6 was supposed to be CAMM2 only, or Am I wrong?Worst case scenario, they will be banned to US markets as Huawei.
By the way, CAMM (2) and LPCAMM (2), those will be more interesting.
Brother, I am sorry, but, legitimately, what the fuck are you even talking about? Who brought up CPUs at all? Why are you insisting on mixing up memory module form-factors with memory types? They aren’t even applicable to most LPDDR use-cases, the vast majority of devices running it have it soldered to their main-board. How is CAMM relevant for Xiaomi who launched a smartphone with LPDDR6? No, LPDDR6 is not a beta for DDR6, what the fuck? Again - different memory types. Not like DDR5 and DDR6, no, more like how DDR and GDDR are different. Or do you think that GDDR6, which has been around for a while, is a “beta” for DDR6 too?
tl:dr - You are extremely confused.
GDDR is different than DDR, that's a fact, the same for HBM.
So if DDR6 is ready to be produced, when x86 CPUs will start using it?
Once the CXMT becomes dominant supplier, they can crush the trio cartel with prices.Historically, DDR and LPDDR were the same architecture until LPDDR4 came out. But since then, it's as you wrote, completely different approach to bus, dies and so on.
