Chen Yao has already established a team for research and development of mobile phone memory!
It¡¯s not just the processor chip that determines whether a mobile phone¡¯s speed is smooth. Memory is equally important. Such critical components have always been monopolized by foreign companies.
Cai Feifei blinked her big eyes: "How is the development progress now?"
As the president of the mobile phone business, even she didn¡¯t know that Chen Yao¡¯s team had been secretly researching and developing mobile phone memory.
The difficulty is too high and the probability of failure is too high. If it is exposed too early, it will attract many media doubts and ridicules, which will bring some trouble to the company's research and development work.
Chen Yao said: "There has been great progress, but to what extent it has been achieved, you and I will go to the R&D base later to see."
After breakfast, they rested in the hotel for a while, then the two of them got up and walked out, driving back to Shenzhen.
The memory R&D base is located in the Semiconductor Industrial Park on the outskirts of Shenzhen City.
About 1 hour or so.
Chen Yao¡¯s Audi R8 and Cai Feifei¡¯s Beetle slowly stopped in front of the R&D building in a factory.
Chen Yao and Cai Feifei got out of the car and walked into the building. .
"Mr. Chen, Mr. Cai, you are here."
A man in his 30s, wearing a blue shirt and looking a bit like a migrant worker, named Zhang Weian.
Although he looks ordinary and looks a little rustic in his clothes, he is the chief scientist of the memory research and development department. He stays in the factory all year round and works with engineers to develop the most advanced memory chips.
As we all know, mobile phone memory is divided into two parts, one is running memory and the other is flash memory.
But whether it is memory or flash memory, the most high-end ones are monopolized by foreign manufacturers. Samsung, Hynix, and Micron alone control more than 95% of the world's market share.
Micron is an American company, and the other two are from South Korea, but the technology basically comes from the United States, and the company is also controlled by the United States.
In other words, the world¡¯s memory chips are controlled by the United States.
Domestic reliance on external memory chips is even more serious than processor chips. At least for mobile phone processor chips, there is Huawei in China, and the processor chips they design have reached world-class standards.
It can be used for memory and flash memory. Domestic mobile phone manufacturers all rely on suppliers from the United States and South Korea.
Domestic memory chips were almost blank before 2018, with a global share of less than 1%. Later, domestic companies began to exert their efforts, and things improved slightly.
But it still lags behind foreign giant manufacturers. The technology gap between one and two generations will take at least 3 to 5 years to catch up.
However, foreign companies cannot wait for you to catch up. By the time you develop it in three years, they will have already launched newer and more powerful ones.
Therefore, domestic memory chips are investing like crazy and quickly jumping to catch up, jumping directly from the 32nd layer to the 128th layer.
From the day he started making mobile phones, Chen Yao decided to make chips, not just processors, but also memory chips. Otherwise, when one day the mobile phone reaches the top three in the world, it will sooner or later be suppressed by the hegemony.
Although Legend has not been developing memory for a long time, it can upgrade quickly.
"Take us in and have a look." Chen Yao ordered him.
Zhang Weian nodded, walked ahead, passed through several passages, and entered a laboratory.
Standing in front of a microscope, Zhang Weian said: "Under the guidance of Mr. Chen, the flash memory and memory developed by the company have made rapid technological breakthroughs. We can already make the best flash memory and memory, but"
Chen Yao looked at the lines on the memory chip under the microscope. After all, the memory chip is also a type of semiconductor. It is almost the same material as the processor chip, which is silicon.
But the quality of the memory produced by different manufacturers varies greatly.
Take flash memory as an example. Technologies such as Samsung and Micron can already produce ufs3.1, with read and write speeds exceeding 800 megabytes per second.
As for memory, giants such as Samsung have already achieved the fifth generation of DDR. Compared with the fourth generation, the transmission rate has increased by 25% to 50%.
Mi Phone 10 is equipped with the latest DDR5 memory. Whether it is playing games or using WeChat, it will be significantly improved compared to the previous generation.
The DDR and UFS currently developed by Legend can achieve the best technology today. The biggest problem is
Cai Feifei hit the nail on the head: "Can't mass production be achieved yet?"
Zhang Weian took a deep breath: "Yes, mass production is still very difficult at present."
Many domestic chip R&D are like this. In the laboratory, very powerful performance can often be achieved, but mass production cannot be achieved. This involves a very refined production process, and the smaller the chip, the more difficult it is to produce.
It just so happens that making chips smaller and smaller is a major trend. Companies like Samsung can already launch 16nm production lines.
Cai Feifei said: "Do you have confidence?"
Zhang Weian said: "If Mr. Chen hadn't been so demanding, we would have been able to mass-produce it long ago."
What he means is that Legend can already achieve the level of Samsung. The reason why it cannot mass-produce now is because Chen Yao's requirements are too high.
Cai Feifei quickly asked: "How demanding is he?"
Zhang Weian raised one finger: "He asked to make a 1nm memory chip!"
Cai Feifei¡¯s big eyes widened instantly!
"Brother Chen, is your request too perverted?" Cai Feifei didn't understand very much.
Since we can do what Samsung did, wouldn¡¯t it be ok to launch a 16nm production line? If you just make 1nm, do you need to make such a big leap?
Chen Yao said with a serious face: "What we have to do is to be the best and be far ahead of our opponents so that they can never catch up. Only by reaching 1 nanometer can we significantly improve the memory performance of our mobile phones."
The bigger the mobile phone memory, the better. Now the largest memory has reached 16gb, but most netizens cannot use it. The memory space has been limited, which is more of an upgrade gimmick by mobile phone manufacturers.
The most critical aspects of mobile phone memory are transmission rate, read and write rate, power consumption, and storage density.
It is also the fifth generation of DDR memory, with the same capacity of 8GB. The production process of Legend Company is more advanced, the power consumption of the memory will be greatly reduced, and the memory will run faster. .
In addition to improving the production process, Legend also needs to develop a new generation of memory to develop a new generation of memory before the international giants do.
In the past few decades, the United States has dominated the world's chip development, not just processor chips, but also memory chips. Chen Yao is going to reverse this situation.
Every year, China imports 300 billion semiconductor chips, of which more than 100 billion are memory chips. This big cake has been eaten by foreigners.
Why are you being eaten by them, but you can¡¯t eat it yourself?
Chen Yao looked at Zhang Weian: "How is the development of ddr6 memory going?" (Remember the website address: www.hlnovel.com - Didn't finish reading?
