On January 16, Changjiang Storage held an annual meeting of partners in Beijing, the meeting was attended by a high specification, from Ziguang Group Chairman Zhao Weiguo to Yang Shining, CEO of Changjiang Storage, to Qunlian, Huirong, Jiang Bolong, ADATA, Guoke micro, etc., it can be said that half of the global storage market has arrived.
At the annual meeting, Ziguang Group Chairman Zhao Weiguo delivered a speech, he first thanked the Yangtze River storage partners. Zhao Weiguo said, “From July 2016 to now more than three years, experienced from 32 layers of research and development, 64 layers of research and development, 32 layers, 64 layers of this change, the process is really very difficult, but also very difficult.” Looking back on these more than three years, there is really a feeling of being so strong that this process, especially thanks to all aspects of support, including the support of the partners here and the media community, because the support and understanding of all of us has come to this day. “
Zhao also thanked the Changjiang Storage team, especially the research and development and engineering team headed by CEO Yang Shining, who he said “can fight hard, including Yang himself is the most talented in research and development among mainlanders.” “
Yang Shining, CEO of Changjiang Storage, also introduced the current progress of Yangtze River storage, he said that the 32-layer stack flash memory stored in the Yangtze River has been produced for more than a year, this product is the carrier of Yangtze River storage learning, through this product, Changjiang Storage has put this basically to the learning, to do high-quality products, All the energy and the principle behind it have been learned.
Yang said the second product of Changjiang Storage is a 64-tier stack of flash memory, which was introduced to the market in the third quarter of last year, and this is the first time they have pushed Xtacking all the way, so because of Xtacking, Changjiang stores in the 64-tier generation storage density, they have reached the world’s best.
Yang Shining said that the 64-tier flash memory stored in the Yangtze River compared with more than 90 layers of products, the density gap of more than 10%, so as long as the Yangtze River storage has a scale, this 64-tier product can still have gross margin, now the main bottleneck is in the scale.
Speaking of the difficulty of doing storage, Yang said, “Storage is not a good industry, I can be very responsible to tell you, actually than I was in Intel when doing CPU is more difficult, CPU difficult in front, finished.” The storage is done here, there’s a lot of work to do behind it, and it’s annoying. “
For the next generation of products, Yang said they would skip the 96th floor and go straight up to 128 and enter as planned.
In Xtacking technology, The next focus of Changjiang Storage is “real functionality and performance advantages.” Even to develop a new business model, so that our customers can come in with a special process and performance to create their own advantages, to achieve a win-win effect. “
64-layer flash memory stored in The Yangtze River
According to the introduction, the Yangtze River storage Xtacking architecture can be achieved in two separate wafers processing peripheral circuits and storage units, is conducive to the selection of more advanced logic technology, improve the flash I/O interface speed, storage density, chip area can also be reduced by about 25%.
When the two wafers are completed, they can be combined together through millions of vertical interconnect channels (VIATs) with just one processing step.
Thanks to parallel, modular product design and manufacturing, Xtacking flash memory can also be developed in three months and production cycles by 20%.
