Chen Yao has long established a team to develop mobile phone memory!

Determining whether the speed of a mobile phone is smooth, it is not just a processor chip, but memory is equally important. Such a critical component has always been monopolized by foreign companies.

Cai Feifei blinked her big eyes: "How is the R&D progress now?"

As the president of the mobile phone business, she doesn’t even know that Chen Yao’s team has been secretly developing mobile phone memory.

The difficulty is too high and the chance of failure is too high. If it is exposed too early, it will attract many media doubts and ridicule, and will cause some trouble to the company's R&D work.

Chen Yao said: "There is a lot of progress, but to what extent it has been done, I will go to the R&D base with you later."

After breakfast, they rested in the hotel for a while, then the two of them got up and walked out, and drove back to Shenzhen.

The memory research and development base is located in the semiconductor industrial park on the outskirts of Shencheng City.

About 1 hour.

Chen Yao's Audi R8 and Cai Feifei's Beetle slowly stopped and stopped in front of a 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 about 30 years old, wearing a blue shirt and looking a bit like a migrant worker, named Zhang Wei'an.

Although he looks ordinary and looks a bit rustic, he is the chief scientist of the memory research and development department. He stays in factories and engineers to develop the most advanced memory chips all year round.

As we all know, mobile phone memory is divided into two parts, one is running memory and the other is flash memory.

However, whether it is memory or flash memory, the highest-end ones are monopolized by foreign manufacturers. Samsung, Hynix and Micron alone have more than 95% of the world's market share.

Meitung is a US company, while the other two are from South Korea, but their technology is basically 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.

The domestic dependence on memory chips is more serious than that of processor chips. At least mobile phone processor chips are available in China. The processor chips they designed have reached world-class standards.

It can be used to rely on suppliers from both the United States and South Korea.

Domestic memory chips were almost blank before 2018, and their share in the world was not even 1%. Later, domestic companies began to make efforts and improved a little.

But it is still behind foreign giant manufacturers. The technological gap between one generation and two generations will take at least 3 to 5 years to catch up.

However, foreign companies cannot wait for you to catch up. When you develop them in 3 years, they have already launched newer and more powerful ones.

Therefore, domestic memory chips are investing wildly, and they quickly jump to catch up, jumping directly from the 32nd floor to the 128th floor.

From the day when Chen Yao made a mobile phone, he decided to make chips, not just processors, but also memory chips. Otherwise, when one day the mobile phones become the top three in the world, they will sooner or later be suppressed by hegemony.

Although Legend has not been developing memory for a long time, the jump speed is very fast.

"Take us in and have a look." Chen Yao ordered him.

Zhang Wei'an nodded, walked in front, walked through several passages, and entered a laboratory.

Standing in front of a microscope, Zhang Wei'an said: "The flash memory and memory developed by the company are under your guidance of Mr. Chen. The technological breakthrough is very fast. We can already make the best flash memory and memory, but..."

Chen Yao looked at the circuit strips on the memory chip in front of the microscope. Memory chips are also a kind of semiconductors, almost the same material as processor chips, all of which are silicon.

But the memory quality produced by different manufacturers is very surprising.

Take flash memory for example. Technology such as Samsung and Micron can already produce UFS3.1, with a read and write speed of more than 800 megabytes per second.

As for memory, giants like Samsung have already achieved the fifth generation of DDR, and compared with the fourth generation, the transmission rate has been increased by 25% to 50%.

The Mi Mobile 10 is equipped with the latest DDR5 memory. Whether it is playing games or using WeChat, it will have a significant improvement compared to the previous generation.

The DDR and UFS developed by Legend can achieve the best technology today. The biggest problem is...

Cai Feifei said to the point: "Can mass production be achieved yet?"

Zhang Wei'an took a deep breath: "Yes, mass production is still very difficult at present."

Many domestic chip research and development are like this. They can often produce very powerful performance in the laboratory, but they are not mass-produced. This involves very refined production processes, and the smaller the chip, the harder it is to make.

But it is a big trend that chips are getting smaller and smaller. Like Samsung, it can already be launched on a 16-nanometer production line.

Cai Feifei said: "Do you have confidence?"

Zhang Wei'an said: "If Mr. Chen hadn't had harsh requirements, we would have been able to mass produce it long ago."

What he meant is that Legend can already reach the level of Samsung. The reason why it cannot be mass-produced now is that Chen Yao’s requirements are too high.

Cai Feifei quickly asked: "How high is he?"

Zhang Wei'an raised one and said, "He asked to make a 1NM memory chip!"

Cai Feifei's big eyes widened in an instant!

"Boss Chen, are your request too perverted?" Cai Feifei was very confused.

Since you can do something like Samsung, it would be OK to launch a 16-nanometer production line. Do you need to cross this big if you just make a 1-nanometer?

Chen Yao said seriously: "If we want to do it, we must do our best, be far ahead of our opponents, so that they can never catch up. Only by achieving 1 nanometer can our mobile phone memory performance be significantly improved."

The larger the memory of the mobile phone, 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 a upgrade gimmick from mobile phone manufacturers.

The most important thing about mobile phone memory is transmission rate, read and write rate, power consumption, and storage density.

The same DDR's fifth-generation memory, with a capacity of 8GB, Legend's production process is more advanced, the memory power consumption will be greatly reduced and the operation will be faster...

In addition to improving production technology, Legend also needs to develop a new generation of memory, and to develop a new generation of memory before international giants.

In the past few decades, the development of chips dominated by the United States in the world has been the same. Not only processor chips, but also memory chips. Chen Yao will reverse this situation.

Every year, domestic imports 300 billion semiconductor chips, of which more than 100 billion memory chips are imported, and this big cake has been eaten by foreigners.

Why are they eating it but they can't eat it?

Chen Yao looked at Zhang Wei'an: "How has the research and development of DDR6 memory been done?"
