Yangtze memory will produce the high end DRAM memory this year based on Defunct German company technology QIMONDA It is 64 layer technology. this article is from last year
The group's affiliate, Yangtze Memory Technologies, is spending $24 billion to build the country's first advanced memory chip factories in the city of Wuhan. It has poached thousands of engineers from Samsung, SK Hynix, Micron and
, and on April 11, it began moving equipment into the factory.
Tsinghua Unigroup Chairman Zhao Weiguo announced that the company should begin producing its first batch of 32-layer NAND flash memory chips this year. But Avril Wu, a longtime market watcher at TrendForce, said it is likely that Yangtze Memory will not be ready to ship the more advanced 64-layer chips, currently the industry standard, until the end of 2019 at the earliest.

After Fujian Jinhua was declared a ban on export by the United States, the domestic storage industry development atmosphere turned low-key, and the industry is more worried that another DRAM independent research and development giant Hefei Changxin will suffer the same fate
But Hefei Changxin chief Executive Director Zhu Yiming first revealed in the GSA MEMORY+ forum on May 15th that the DRAM technology under development is based on the technology of Qimonda, a German-based storage giant that used to own a global patent.
In the past two years, Zhu Yiming, who was very low-key in public exposure, and the GSA MEMORY+ forum on the 15th caused a sensation in the industry. He was prepared to come out with a "answer" and "antidote". Zhu Yiming announced that the technical basis of Hefei Changxin is Qimonda. “Answer” worried about Changxin’s infringement of Micron’s DRAM technology and patents, and also broke the news that Changxin’s “Help” Samsung technology transfer technology.
This declaration is an "antidote" for the domestic independent storage industry. Zhu Yiming said that the first is through the cooperation with Qimonda, and combined with the research and development of Changxin's independent technical team, there are already more than 1,000 DRAM-related technologies, and the paper is cooperating with the equipment lithography machine ASML.
The pilot production line was pre-developed. Hefei Changxin completed the wafer plant in just 14 months and has already produced 15,000 test wafers with a capital expenditure of US$2.5 billion. To interpret the information release of Hefei Changxin, the significance of domestic independent development of memory chip technology must first be discussed from the three major aspects:
1. Why is Hefei Changxin going to be eye-catching? 2. Before Qimonda collapsed, it actually developed a martial arts” in the DRAM industry. Unfortunately, there is no money for mass production. Is this a history of unfinished work? 3. Is there any precedent for the success of the operator of Qimonda DRAM technology, which can be used by Hefei Changxin?
Why is Hefei Changxin going to be eyed by Meiguang? In 2017, the US storage giant Micron offered two killers, aiming to cut off the technological autonomy of the domestic storage industry. First of all, it was a big move to send a letter to hundreds of employees of Taiwan storage company Huaya Ke to Hefei Changxin, taking legal measures and international pressure to prevent the transfer of talents, which triggered the shock of the international semiconductor industry. In addition, it
