721 Chapter 720 The world's second memory stick [seeking subscription]

"I, I decided to cancel my business trip to the capital and go to Nan'an City with you." After regaining consciousness, Professor Long stroked his sparse gray hair.Seeing is believing, he felt to take a look at the 1G memory stick Xu Zhenming said.

The technical concept of 1G memory stick was first proposed by Korea Sanshin Electronics Co., Ltd., and supported by American TI company and island companies such as Mitsubishi, Fujitsu, and Toshiba. It is currently the latest new standard in the world.

This kind of memory stick uses DDRSDRAM technology, in order to achieve good heat dissipation effect, the volume is relatively large.Not only that, this is also the future development direction of personal PC computer memory.Therefore, Professor Long is very curious and thinks that the team of Yiming Group has done an incredible thing.

Seeing his astonishment, Shen Yi smiled and said, “Okay, Professor Long. I’m just waiting for your words. The team members of our Yiming Lab have made various preparations and can test and demonstrate this at any time. 1G memory stick."

Because of this concern, Professor Long didn't bother to carefully check the performance of 1000 Xenia-128SDATA hard disk array cabinets.He handed over the inspection work to his subordinate Wang, and flew to Suning City with Xu Zhenming that night.

Early the next morning, Professor Long and Xu Zhenming took a special car from Er Liu Kai to the compound of Mingxin Manufacturing Company.

At this moment, Zhou Jiawei led the team members of the DDRSDRAM memory module project team, standing in line outside the steel structure of the laboratory, waiting for Xu Zhenming and his party.

"Professor Xu Dong and Long, we have made preparations. Are we going to the conference room or the memory test laboratory?" Zhou Jiawei happily shook hands with Xu Zhenming and Professor Long.

Hearing the words, Professor Long couldn't wait to say: "Of course, go to the memory test laboratory first."

"Okay, let's listen to Professor Long." Xu Zhenming suddenly waved to Zhou Jiawei when he saw this.In fact, he is very confident in today's inspection and verification procedures, and he is not afraid of what methods Professor Long will use to test and experiment.

Zhou Jiawei is the same, winking at a Goryeo engineer behind him, "Lao Li, let's go to your laboratory first."

"Yes!" Li Hongfan, in his forties, bends down to Zhou Jiawei and bows.

Li Hongfan is not simple, he is Xu Zhenming commissioned by the general manager of the Yiming Group Korea Branch Liu Jing, a memory technology expert dug from Korea.

Li Hongfan is an expert in the development of memory sticks in the Korean Xiangdai Company. He is very famous in Korea and once worked in the LG-Xiangdai joint venture.

After this Lejin-Xiangdai joint venture was acquired by Yiming Group, Li Hongfan was temporarily unemployed and planned to work at the headquarters of Xiangdai.However, Liu Jing did not let go of this high-tech talent, and set up a semiconductor laboratory in Korea, leaving Li Hongfan and others behind.

With the development of Yiming Group, its reputation in the international arena has grown, and Li Hongfan and others have gradually developed a sense of belonging to Yiming Group.Seeing that the timing was good, Xu Zhenming transferred him to the headquarters of Yiming Group to be responsible for the research and development of 1G memory projects.

Therefore, in terms of memory module technology, Yiming Group is not much worse than Sanxin Electronics and Xiangdai Electronics in Korea.Sanxin Electronics has already put out 1G memory sticks this year, and Yiming Group should make 1G memory sticks now.

But Professor Long didn't know the situation, so he asked Zhou Jiawei curiously, "Zhou, I don't think this group leader Li seems to be an engineer in our country, so speaking Mandarin is a bit unfavorable."

He paid particular attention to the technical sources and authenticity of 1G memory sticks, so he paid close attention to Li Hongfan's words and deeds.

"Haha! Professor Long is right this time. Our group leader Li is a Korean national and one of the drafters of the DDRSDRRM memory module specification agreement. His reputation in the memory module industry is not small." At this time, Zhou Jiawei gave a brief introduction of Li Hongfan's situation with a smile on his face.

At the same time, Li Hongfan stopped and turned around to salute Professor Long, "Ahem, cough, those are all false names and countless Professor Long." He is relatively modest, unlike some experts who are so bullish and beeping. Beep.

For this, Professor Long still appreciates Li Hongfan's good character."Um... It turns out that there is an expert Li sitting here, no wonder our Yiming Group can take out 1G memory sticks so quickly." He put on a high hat on Li Hongfan by the way to narrow the distance between the two.

Li Hongfan didn't show too much enthusiasm because of Professor Long's words, but smiled at Professor Long, "Professor Long, please here."

While talking, a group of people came to the memory test laboratory.The layout of this laboratory is very similar to the layout of the chip test laboratory, with the middle two rows of laboratory benches facing each other.On the blue workbench there is a sliding computer board placed on the white foam board.

A brand new 1G memory stick is inserted into these computer boards, and the computer board is working to transfer the data of the 1G memory stick to the experimental database of the testing and testing workstation.

Seeing this scene, Professor Long hurriedly stepped up and walked to the computer screen of a test workstation."Uh? The speed is very fast, the usage rate of 1G memory has not reached 30%." He whispered while watching the dynamic data of the 1G memory stick.

Professor Long was right. All the 1G memory modules in the laboratory did not reach the upper limit of memory module usage due to the test of the computer version.In this era, PC software does not require high memory, and 1G of memory can be described as a massive amount for those software.

But anyway, Xuanniao operating system has managed the space of 1G memory and can give full play to the performance of this 1G memory stick.

"Professor Long, do you want to see the real efficiency of our memory?" At this time, Zhou Jiawei came to Professor Long and asked Professor Long with a smile.

From the perspective of technical personnel, or from the perspective of the needs of the Galaxy III project, Professor Long would definitely want to see how this 1G memory is running at full capacity.

He nodded with a firm gaze, "For our Galaxy III supercomputer, it is best to install 32G of RAM, so that the supercomputer's CPU performance can be fully utilized."

"Okay, just follow your request." Seeing this scene, Xu Zhenming winked at Zhou Jiawei and Li Hongfan.

With Xu Zhenming's hint, Li Hongfan understood it, and hurriedly knocked on the memory bar testing workstation in front of him.As he hit the Enter key, the workstation instantly ran an infinite loop mathematical calculation software.This kind of simulation software for big data calculation requires very large memory.

Because after the calculation of this software, the data curve of this test workstation changed instantly, and the usage rate of 1G memory burst from 28.56% to 98.75% in an instant.

Not only that, the usage rate of 1G memory is constantly changing dynamically, around 90% for a while, and around 50% for a while.This data collection is synchronized with the refresh circuit of the computer motherboard. The faster the computer motherboard, the faster the data refresh rate of the 1G memory stick.

"Well, this 1G memory stick fits our Galaxy III project." After seeing this, Professor Long rubbed his hands in excitement.

Because the working mode of this DDRSDRAM1G memory is synchronized with the refresh circuit of the computer motherboard, there is no restriction on the performance of the Galaxy III supercomputer.Therefore, as long as the computer board of the Galaxy III supercomputer is fast enough, the performance of the 1G memory stick can keep up.

This is the matching memory stick that Professor Long has been looking for!

According to his original plan, if the technology of domestically-made memory modules is not good enough, the Galaxy III project team must order from Korea Guosanxin Electronics.And now, this test by Li Hongfan has given Professor Long the hope that our country does not need to ask Koreans at all.

So Professor Long was very excited, "Leader Li, can you increase the frequency of the circuit refresh of this 1G memory stick?"

"Professor Long, no problem."

"How do you solve the 32-bit dynamic addressing problem of 1G memory?"

"This...this is our patented technology, it's not easy to reveal."

"Strong! Your team is very strong, and the technology is very strong! Hahahaha...good." Professor Long was a little incoherent, checking the test data back and forth from one workstation to the other.

In other words, Li Hongfan's team is very careful, separating all the hardware data of the DDRSDRAM1G memory module, and a testing and testing workstation is responsible for the testing of a single data.Therefore, the data that Professor Long saw was very detailed and very intuitive, and there was also a detailed curve chart.

He knows this is the characteristic of Yiming Group, and he likes to use graphs, histograms, data tables and other modes to reflect the test data of products.

It is precisely because of this intuitive data that Professor Long can see the performance difference between this 1G memory stick and Sanxin 512MB memory stick at a glance.

"Six or seven times faster than the Korean 512MB memory stick, the data refresh rate gap is even bigger. Um... we need this memory stick." He grinned and shook the report data in his hand.

In this era, the memory of PC computers is very expensive, and the price of 1MB of memory is about 500 yuan.Professor Long needs 32G of RAM, which means that he has to pay more than 10 million yuan.This business is not a small amount, and Xu Zhenming of course attaches great importance to it.

"Lao Zhou, you should act according to Professor Long's instructions, and immediately prepare to arrange production tasks so that Lao Zhang is ready to produce 32G memory."

Xu Zhenming followed Professor Long's will and immediately arranged production tasks.He doesn't want to lose this big order, besides, there is also a Galaxy III project to test the performance of 1G memory sticks, why not?

Hearing this, Zhou Jiawei was also very happy, and immediately took out his mobile phone to call Zhang Nyjin's number.

Large orders for 32G memory sticks are rare in this era and can only be produced according to orders.For this 1G memory module project, Yiming Group has burned more than one billion yuan, and now it is finally time to reap the results. Zhou Jiawei, Li Hongfan and other team members are all smiles at this time and are in a good mood.

Seeing this scene, Professor Long finally reacted, "Am I a bit reckless and not rigorous in doing this?" With this thought in mind, Professor Long immediately calmed down and retested the DDRSDRAM1G memory stick again. Various technical parameters.

After inspection, he found no defects or BUG."The production technology of Yiming Group is indeed very good. The workmanship, circuit layout, and selection of electrical components of this memory are all good. From this point of view, my order task is fine." Professor Long nodded secretly.

At this time, Li Hongfan, who was standing next to him, asked in a low voice: "Professor Long, how about we go to the conference room? I can introduce the principle of this memory stick to you in detail."

"Okay, that's it." In order to redeem his rashness, Professor Long also wanted to learn more about the design principles and framework of this 1G memory stick at this time.

Not long after, everyone moved to the confidential meeting room of Zhou Jiawei's laboratory.At this time, this meeting room is also ready, with fruits and snacks on the meeting table, and a PPT document projected on the wall.

Seeing this scene, Professor Long didn't bother to eat fruit. He found a place to sit down, but his eyes stayed on the big projection screen.

At this moment, what is displayed on the large projection screen is the protocol specification of the DDRSDRAM memory module and the design principle of the 1G memory module of Yiming Group.

"Let's start." After scanning around, Professor Long saw that Xu Zhenming and others were already seated, so he couldn't wait to discuss with Li Hongfan.

Li Hongfan heard this and glanced at Xu Zhenming.

Xu Zhenming's face was very calm at this time, he was picking up a longan and peeling it.He slightly nodded to Li Hongfan and signaled Li Hongfan to start introducing the technical principles of 1G memory sticks.

"Professor Long, Dong Xu, and leaders, the DDRSDRAM memory technology agreement was jointly drafted by nine companies including Yiming Group, Sanxin Electronics, Xiangdai Electronics, Island Electric, Mitsubishi, Fujitsu, Toshiba, Hitachi, and Texas Instruments. A new technical standard for memory modules."

"The technical specifications of this memory module have been supported by chipset manufacturers such as AMD, Longteng Computer, Yiming Group, VIA, and SIS, and will definitely become the mainstream of the industry in the future. Therefore, we don’t have to worry about the impact of this DDR type of memory module. If you are eliminated, you just need to keep developing new products."

Old God Li Hongfan is introducing the origin and principle of DDR memory specification, including some technical parameters.

The technical parameters he mentioned are public parameters, so manufacturers supporting DDRSDRAM memory sticks must support them.

"Huh..." After hearing these words, Professor Long finally breathed a sigh of relief.He believes that this more than 10 million yuan is not in vain, and if you invest in it, you can immediately get a world's most advanced supercomputer.

In other words, supercomputers are the face of a country's computer technology. At present, only the United States, island countries and China are vying for the first place.

It stands to reason that the economy of China is much worse than that of the island countries and the United States, and there is no need to compete for this kind of fame.But what about Professor Long if the headquarter leaders have orders?He didn't dare to object, and he thought it was a glorification for the country.

And Professor Long didn't know that in the near future, the memory sticks of personal computers will use 1G memory sticks, or larger storage capacity.

In other words, the 32G memory stick invested by the state will soon become obsolete.
