China’s top memory chipmaker, CXMT, will supply its latest LPDDR6 DRAM chips for Xiaomi’s upcoming flagship ​folding phone, the companies said on Saturday.

ChangXin Memory Technologies ‌has started mass production of LPDDR6, which will supply Chinese smartphone maker Xiaomi’s new foldable phone 18 Fold, CXMT posted on China’s Weibo ​social media platform. LPDDR6 arrived less than a year ​after CXMT mass-produced the previous generation of LPDDR5 chips.

Xiaomi, ⁠one of the world’s largest smartphone makers, confirmed the ​plan on its official Weibo account. The company said the new ​foldable phone will be released in September.

LPDDR6 is CXMT’s most advanced Dynamic Random-Access Memory chip for mobile devices, narrowing the company’s technology gap ​with China’s top DRAM maker and global peers such as ​Samsung and SK Hynix.

Xiaomi said this week the upcoming folding phone is ‌expected ⁠to use a new version of the company’s in-house 3-nanometre handset processor Xring O3, which would support LPDDR6.

On Friday, CXMT posted a sharp turnaround to profit in the first half in ​its first earnings ​release since listing, ⁠while revenue spiked 874 percent from a year earlier to 150.3 billion yuan ($22.36 billion).

The Hefei-based company ​said it had shipped to customers samples of ​its ⁠LPDDR6 DRAM chips, which are to be used on mobile devices, servers and smart cars, to customers.

Also on Friday, CXMT sued the ⁠Pentagon ​over being placed on a list ​of companies the U.S. says are aiding China’s military. The Pentagon declined to ​comment on ongoing litigation.
