The Red Era, the Opening University Speech

Chapter 268 It won’t be long before I see you in the newspaper again
Of course, this problem is actually not difficult to solve. Dynamic random access memory itself is also a kind of semiconductor memory. Xiaguo is still quite strong in this area of ​​technology. We only need to allocate some manpower to research and development.

Next is the research on static random access memory.

As a semiconductor memory, its technical difficulty is much simpler than the former, which is why Professor Bai, who is in charge of the research of the storage system group, put it in the second place for research.

But simplicity does not mean that it has no technical difficulty.

As a high-speed but relatively volatile memory, how to improve storage density, reduce power consumption, maintain data stability and optimize read and write operations are four difficult design challenges.

……

Inside the storage system development team laboratory.

As the team leader, Professor Bai listed the obstacles encountered in the current research one by one.

After he finished speaking, everyone in the room focused their eyes on Li Mu, who was concentrating in deep thought, their eyes full of anticipation.

As veterans in the institute, they all knew that Li Mu would definitely be able to give them a solution quickly.

But this time he did not rush to give an answer. Instead, he looked at the young people in the storage system development team and said, "Wang Ben, Wei Liguo, and Xu Qiangbang, you guys tell me your opinions."

When the three young men who had just entered the research institute heard Li Mu give out their names, they showed surprise on their faces.

But when they heard that they had to answer questions, they all looked at each other and no one dared to be the first to speak.

Seeing this, Li Mu smiled and said, "It's okay, just talk casually, relax a little, and treat it as a learning exchange."

"Yes, let me be frank. Consultant Li is younger than all of you. What are you afraid of?" The professors around him saw what Li Mu was planning and laughed.

But these words made the three of them even more nervous.

They are indeed older. When they were their age, they had not even graduated from college. But the person in front of them has already become a nationally renowned scientist, an object that countless students are eager to learn from and emulate. Even they admire him so much that they can't compare with him at all.

Finally, Wang Ben, who had a rougher look, swallowed his saliva and spoke first: "Advisor Li, I think we can improve storage density by increasing integration."

After he finished speaking, he stopped and looked at Li Mu's reaction.

Even though he knew it was okay to say something wrong, he just felt nervous for no reason.

"Good, keep going." Li Mu nodded slightly to express his approval.

Seeing this, Wang Ben became a little bolder and continued, "As long as we make further breakthroughs in integration, the storage density will naturally be improved."

"But the key to the problem is how to improve the integration level, right?" Suddenly, Wei Liguo, who was standing behind Wang Ben, interrupted and said:
"Our highest integration level last time was 5w. Although it has increased thanks to Professor Huang and his colleagues' unremitting efforts, the improvement is not obvious."

"It is not ineffective to use this method to increase storage density, but the effect may not be ideal."

At this time, the last one, Xu Qiangbang, saw that both of them had spoken, and said in a deep voice: "Yes, I think we still need to find a way from the design point of view, optimize the current storage unit structure, and adopt a high-density design method."

……

The three of them spoke one after another, expressing their own opinions.

Li Mu and other experts and professors saw this and all had smiles in their eyes.

"You all make sense." He nodded slightly, and then said, "Whether it's improving the integration or optimizing the design, we can actually do both at the same time."

"Let's not talk about the former for now. Let me talk to you about the latter and how to optimize its design structure."

"In the past, our storage units were mainly in binary format, such as punched cards, magnetic tapes, and early disks. Although they were later converted to multiple binary bits, the improvement effect has now reached a bottleneck."

"So, how do we break through this bottleneck?"

As he spoke, he looked at everyone in the laboratory.

This question requires everyone to answer it together.

But seeing how they are frowning and thinking hard, I'm afraid they won't be able to come up with an idea for the time being.

Li Mu could only continue: "In fact, the method is very simple, that is to add a port."

"Add a port? Wouldn't that make the size even bigger?" an old professor wondered.

Others couldn't help but look at each other. Could it be that Li Mu's method was simply to increase the volume?

Hearing this, Li Mu explained:

"Of course, it's not just about increasing the size. My idea is to duplicate and add a set of read and write ports based on the original single port."

"Each port has independent read and write word lines and read and write dimension lines, allowing each port to perform both read and write operations."

"But structurally, only two transistors are needed, and the memory cell area is expected to increase by about 40%. Adding additional sense amplifiers, write drivers and row decoders can significantly improve efficiency."

"Great, this is indeed a good idea, worthy of being Consultant Li!" Wang Ben and others couldn't help but exclaimed.

The other professors also agreed and said:

"Consultant Li is right. If the two ports can read and write independently, the efficiency can indeed be greatly improved."

"It also improves the parallel processing capability of data, reduces access latency, and greatly increases the efficiency of the entire system."

"Yes, compared with the increase in integration, this method is obviously better. I can't wait to start experimenting!"

……

Listening to everyone's praise, Li Mu smiled slightly, without being modest, and accepted it frankly.

Afterwards, he continued to talk to everyone in detail about how to realize the development of dual-port static random access memory, and then got up and left.

Of course, even if a plan is given, it is not a complete solution.

Dual ports are not so easy to achieve, and there is a very critical issue involved. He deliberately kept it a secret and prepared to let them study it themselves first, in order to cultivate and train their scientific research capabilities to overcome difficulties.

"I hope it can be solved." Li Mu walked in the corridor with anticipation in his eyes.

If this can cultivate a group of useful talents, he will be able to work much more easily in the future.

Just as Li Mu was about to continue to the processor development group, suddenly, a voice called him from behind: "Li Mu, there's a call from President Guo."

Hearing the sound, he turned around.

Wu Youxiang must have come here at a jog, and he was still catching his breath.

"Okay, I'll go right away. Director, please tell them that I won't be back today." When Li Mu heard this, he knew that it must be news from Tang Yanjie.

He raised his wrist to look at his watch. It was already past 2 p.m., so it might be unrealistic to go there and come back.

Wu Youhao suddenly realized, "It seems that you already knew it. President Guo asked you to follow the car sent by the Aviation Institute. I will accompany you down."

As he said that, he and Li Mu walked downstairs. As they walked, he asked curiously, "What have you come up with that even alarmed the Aviation Institute?"

"I just had some ideas about the helicopter. I didn't expect it to cause such a big noise." Li Mu smiled faintly and didn't make his words too clear.

But this is enough for Wu Youxiang.

He looked at Li Mu and couldn't help but gave him a thumbs up and said:
"Okay, you made a big noise without making any noise!"

"It looks like it won't be long before I see you in the newspaper again!"

Given Xia's current international situation, helicopters, as powerful military weapons, will definitely be unveiled to the world once they are successfully developed, causing deterrence to neighboring countries.

For the Xia Kingdom now, it is more cost-effective to avoid fighting as much as possible rather than fighting a battle with an unknown outcome.

"Then I'll borrow your good words." Li Mu smiled.

As they were talking, the two of them arrived at the gate.

After confirming the identity of the person, Li Mu followed him into the car and headed for the mysterious Aviation Academy.

……

The military green jeep sped through the suburbs for two hours before stopping at a mountain pass.

Then, the guard in the car called Li Mu down.

They need to walk for the rest of the journey.

As a military research unit with a very high level of confidentiality, the location of the Aviation Institute must be extremely secretive, but Li Mu did not expect it to be so secretive.

After walking for more than an hour and going around a valley, he finally saw the research base hidden in it.

Before they could get close, a sentry came out to check on them.

The questioning was extremely strict. Even though he had an ID, the other party still asked someone to go back and report to the research base before letting him go.

……

Afterwards, Li Mu continued to move towards the entrance of the research base.

Before he got close, he saw Tang Yanjie. Behind him stood a group of leaders, as well as many experts and professors who looked knowledgeable.

Seeing him coming, a group of people hurried forward to greet him.

Seeing this welcoming scene, if someone didn’t know, they might think that some important leader came to inspect, which scared Li Mu.

Tang Yanjie shook his hand vigorously and said, "Welcome, welcome. We have been looking forward to seeing you here for a long time. Consultant Li, please come in."

"Dean Tang, you are embarrassing me. There's no need to be so polite." Li Mu waved his hands repeatedly.

Although he has achieved a lot now, what does it mean in front of this general who has carried a gun and fought in battles and has countless military exploits!

Hearing this, Tang Yanjie laughed twice and said, "Then I won't be polite. Let's walk as we go."

"Let me first introduce you to the people in our institute. This is Wang Zhenqian, the Party Committee member, this is Liu Hongzhi, the director of the first institute, Liu Su, the director of the second institute, and Chen Yufeng, the director of the third institute..."

He introduced the directors of the research institutes under the Academy of Aeronautics one by one.

Li Mu hurriedly shook hands and greeted everyone.

After introducing all the directors, Tang Yanjie continued to introduce the experts and professors in the institute.

The first person to introduce the team was a man in his 37s or 38s, wearing glasses and with a square face. He said, "This is Professor Wang Shicun, a great expert in helicopter technology in our country. After reading your plan, he is very sure of your idea!"

"Hello, Professor Wang, I have heard of your name for a long time. I have read your 'Generalized Vortex Theory of Helicopter Rotors', which has benefited me a lot!" Li Mu stretched out his hand and shook hands with the other party tightly.

In the past two days, he has looked at the current information on domestic helicopter research, and Wang Shicun is definitely the most dazzling one.

He was a pioneer in the helicopter technology field in Xia State, one of the founders and academic leader of the helicopter profession. The vortex theory he published on the big brother side was called "Wang's vortex theory."

In terms of ability, there is nothing to say.

Wang Shicun saw Li Mu's eyes and realized that he was not being polite but really admired him. He smiled and said, "I can't compare to you, Consultant Li. You are young and promising. You won the National Highest Science and Technology Progress Award at the age of 23."

Although it was just a business compliment, he couldn't help but sound envious when he said this.

A national award is the ultimate dream of almost every scientist, and it’s the kind of award that one can brag about for the rest of their lives.

Even if he doesn't brag, others will follow suit, just like him.

Facing Wang Shicun's praise, Li Mu could only change the subject and said, "It's just that I was lucky and achieved some results. Let's not talk about this. Professor Wang, you have read the plan for the Xuanniao-1 helicopter. I want to ask your opinion."

"Wait a minute, let's go to the conference room to talk. There's a large group of people waiting for you, Consultant Li!" Tang Yanjie interrupted their conversation and said.

Li Mu and Wang Shicun looked at each other and said immediately, "Okay, then Dean Tang, let's go."

After saying that, he followed everyone and continued walking deeper into the research base.

……

Come to the big conference room.

The place was already full of people, and some people had no seats left, so they had to move their stools and sit in the aisle.

Li Mu took a quick glance and estimated that there were at least ninety people.

It seems that for the independently designed and developed Xuanniao-1 helicopter, Tang Yanjie probably mobilized all the available researchers from the ten research institutes under the Academy of Aeronautics.

Don’t think that more than 90 people are too few. Just by looking at their ages, Li Mu can tell that those who come are the backbones of various research institutes, and there are almost no young faces.

After coming in, Tang Yanjie first arranged a seat on the stage, sitting on his left, while Wang Shicun sat on his right.

He cleared his throat and said, "Everyone, please be quiet. Let's not rush to ask questions. Let's ask Consultant Li to introduce the design of the Xuanniao-1 helicopter to us first."

"Consultant Li's explanation is definitely more detailed than the plan. Let's listen first and don't ask non-essential questions to avoid wasting time."

The people from the Institute of Aeronautics studied and discussed it for two days. Some superficial questions were naturally not difficult for them, but they could not make breakthroughs in more in-depth problems.

Even with Li Mu's plan, there has never been a precedent for China to independently develop helicopters, and many people have cognitive bottlenecks.

There were even some people who simply doubted whether they could build a helicopter.

Li Mu picked up the microphone, coughed twice, and said:

"First, let me tell you about my thinking behind this design..."
