Just a few days ago, the PC DDR4 memory stick with the Violet National Core logo was exposed online, which is a completely self-developed DRAM pellet. The single capacity is 4GB, and the specific parameters are unknown. In January of this year, Ziguang Group invested 200 billion yuan to build a semiconductor base in Nanjing. After completion, it will become China's largest semiconductor production base with a monthly capacity of 100,000 wafers. In July last year, Ziguang Group also participated in the Yangtze River storage. Investment, plans to invest 160 billion yuan to build domestic 3D NAND flash memory and develop DRAM.

The memory modules we know are only a small part of the entire semiconductor industry, and the consumer-grade market is one of them. So is China investing hundreds of billions just for this small and inconspicuous market? Next, we will analyze why domestic semiconductors are so fast and powerful from several angles.
Prevent back door
Some time ago, Intel exposed the ME event, which confirmed that there is a completely independent system inside Intel's processor. It consists of one or more cores and memory, clock, and bus for the encryption engine's reserved memory. Even with a separate operating system and applications, you can read the memory of the main system and link to the network through the network controller.
More importantly, this system can be run while the computer is sleeping or even shutting down. As long as Intel wants, the ME can completely control the user's computer completely without the user's knowledge. It can control boot, shutdown, read all open files, check all running programs, track user's keyboard, mouse actions, and even take screenshots.
These have little impact on the average user, hundreds of millions of processors around the world, and our individual users are not much value to be monitored. However, if it is a national security-related department that uses its processor, or is used in military applications, it is very dangerous. Therefore, if our confidential department uses Intel's processor, it may be taken back by others, stealing secrets and even critical equipment is controlled.
However, high-end semiconductor products such as memory and processors have long been monopolized by foreign manufacturers. As the degree of informatization of the country and society has rapidly increased, if there is no semiconductor product with completely independent intellectual property rights at this time, the mission will be in the hands of others. Hands.
Curved overtaking
Intel has been in existence for 49 years since its founding in 1968. At that time, China's situation did not allow the large-scale development of the semiconductor industry, which was relatively backward. Today, China has considerable financial resources. It is the second largest economy in the world and has sufficient resources to develop the semiconductor industry.
The most typical representative of domestic semiconductor products is the Godson. The Godson is a domestically produced processor that has its own property rights. It is mainly used in the national sector. Its use is mainly for security purposes. Although there is still a certain gap from the current consumer-grade high-end processors, the speed of the gap is much smaller than the speed of the processor development in the past. It can be said that it is advancing rapidly.
At present, Godson No. 3 also has corresponding development board products for sale. It needs to fill in the developer information on the official website and sell it to you in accordance with certain conditions. The main purpose is to let developers learn and develop research on this system and enrich the software resources. To create a stronger ecosystem.
Preparing for the future
China's R&D production capacity is very influential in the world. I think the world is very familiar with the word "MADE IN CHINA". For this reason, some countries with very developed semiconductor industries have joined forces to limit the development of China's semiconductor industry. The most typical one is the lithography machine. Without this device, even if the circuit of the semiconductor device is designed, the chip cannot be carried out without a lithography machine. manufacture.
Under normal circumstances, the products manufactured by the lithography machine using a certain process will not produce any profit, and the lithography machine that has already eliminated the process will be exported to us, and the price is still high.
At present, it is still difficult to establish a complete mainstream processor manufacturing system in China. However, although it started very late, under the powerful reserve force, it is very promising to break through the difficulties. At present, the accumulated semiconductor industry in China has invested about 500 billion yuan to build a complete industrial chain. In the future, I believe that research and development will definitely make the world use high-end semiconductor products made in China.
