Huawei Mate 40 Series Memory
Earlier this month, there were reports that the Huawei Mate 40 series was suspected of using Huawei’s own flash memory, which sparked some controversy. Now, the mystery is finally solved: the Huawei Mate40 Series memory uses 64-layer 3D NAND flash memory particles from Yangtze River Storage.
In September last year, Yangtze River Storage was the first to announce the mass production of 64-layer stack 3D flash memory in China, and when it comes to domestic flash memory, many people say they haven’t seen it.
Recently, Yang Shining, CEO of Yangtze River Storage, said during an event that compared to international storage makers, the company took just three years to realize the leap from 32 to 64 layers to 128 layers, completing in three years what they have done in six years.
Besides, Yang also confirmed that their 64-layer flash memory has made its way into Huawei’s Mate 40 supply chain, and to borrow a phrase from the Internet, he said, “the peak is the debut.”
This means that Huawei’s Mate 40 series phones are increasingly using the domestic supply chain, including core products like flash memory, which used to be mainly supplied by Samsung, Armor Man, Western Digital, Micron, and the other U.S., Japanese and Korean companies.
The flash memory capacity of Huawei Mate 40 series cell phone is 128GB, 256GB, 512GB three, measured sustained read, write speed reached 1966MB/s, 1280MB/s, this performance is faster than the UFS 3.1 flash memory, a netizen reported that this is Huawei’s self-developed SFS flash memory technology, the main control chip is the HiSilicon.
For comparison, the read and write speeds of the Mi 10 Ultra, which uses UFS3.1 flash memory, are 1772MB/s and 789MB/s; those of the Samsung Note20 Ultra are 1750MB/s and 736MB/s, respectively. In comparison, the Huawei Mate40 Pro’s flash writes performance is significantly improved, with some increases of even more than 70% compared to the competitor’s flash performance.
However, we all know that Huawei itself is not a memory chip manufacturer, and cannot develop and produce flash memory chips. At present, mainstream flash memory manufacturers such as Samsung, SK Hynix, and Armor Man are self-researching, self-producing, self-selling, and do not have the business of OEM storage chips for third parties.
The company’s products have been developed by several companies, including Samsung, SK Hynix, Armor, and other mainstream flash memory manufacturers, and then with self-developed or third-party flash controller and firmware, and then their own (or outsourced) packaging test, printed with their LOGO and other manufacturers.
So, for Huawei, the flash memory chips with Huawei’s logo on the Mate 40 series are probably flash memory pellets sourced from some flash memory maker, and then added a self-developed flash memory controller (Huawei has always had its self-developed flash memory controller chips), which is then packaged by a third-party packaging and testing facility. This explains why the Mate 40 Pro’s flash memory performance is far superior to that of other UFS 3.1 standard flash memories.
