ChangXin Memory Technologies (长鑫科技; SSE: 688825) began fifth-generation process mass production; associated products have not yet achieved scaled sales.

ChangXin Memory Technologies (长鑫科技), identified in the supplied announcement summary as 688825.SH on the Shanghai Stock Exchange (SSE), announced fifth-generation process-platform mass production at the World Manufacturing Convention on September 20. It simultaneously displayed high-capacity LPDDR5X, or low-power double-data-rate 5X memory, built on that platform.

A separate daily-news summary in the supplied messages identified a displayed LPDDR5X product as 24 GB. This is a memory-product capacity, while “fifth-generation” refers to the company’s process technology platform.

The company explicitly stated that products manufactured on the new platform had not yet achieved scaled sales as of the disclosure date. It also said the development would not materially affect near-term operating results, preserving the distinction between manufacturing readiness and commercial revenue contribution.

The announcement described the platform as helping broaden the product portfolio and strengthen competitiveness, but supplied no quantified performance comparison. The available evidence is Telegram coverage of the company announcement, not the original exchange filing, and contains no process-node dimensions, production yield, wafer capacity, or product-pricing details.
