Chapter Seventy-Seven: Progress Has Been Made

Rolls-Royce drove all the way to the high-end apartment community of Ling's Group, Yan Xiaoyun's mother, younger brother and sister, who had already received the notice, had been waiting for a long time, and when the car came, they put their luggage into the back box of the car, got into the car, and the car did not stay long and started again, leaving the community.

After placing the family in the small villa area prepared for them by Ling Shizhe, he took them to see the house where Yan Xiaoyun lived.

Looking at the vast manor villa, Yan's mother and younger siblings were shocked by the luxury of the manor, Yan's mother was better, after all, she had some insight as a rich wife before, but Yan Xiaoyun's younger brothers and sisters were not good.

Seeing the ugliness of the two children, Yan's mother reprimanded them, then sent them away, let them go to other places to play, and took her daughter's hand to sit down in the artificial lake pavilion, Yan's mother said to Yan Xiaoyun: "Are you really going to be his little wife?" ”

"Hmm......" Yan Xiaoyun nodded with a blushing face.

Hearing her daughter's answer, Yan's mother burst into tears and cried: "Life, this is all fate, how did our Yan family say that it was also a rich family before, you are the daughter of the Yan family, if your father didn't speculate in any stocks, you wouldn't end up being a little wife, he was good, he left, and left us, Mom can't help you...... Woo...... Woo......"

"Mom...... Stop it...... Woo...... It's not my mother's fault, it's my own will, he took me very well, except that he has no name, Mom, don't be sad, woo......"

The mother and daughter hugged their heads and cried, pitiful of their fate, if Yan Xiaoyun's father Yan Shiqing hadn't been instigated by others, playing with any stocks, he would not have been put in a cage, not only lost all his family property, but also owed a lot of bad debts, and the Yan family would not have ended up today, so it is okay to play with a little spare money for stocks, but you must not invest the entire family property in it, let alone borrow money to speculate in stocks.

What's more, there are too many kinds of financial scams in the securities market in Hong Kong at this time, and people who don't know anything about the stock market can take some spare money out and buy one or two stocks that they are optimistic about to hold lazy stocks for a long time, which is the best way to invest.

Yan Xiaoyun's father fell for this kind of vicious financial scam, thinking that he could make money, he was the god of stocks Buffett, but in fact, he didn't understand anything, not only invested all his family property, but also borrowed a lot of loan sharks, but in less than a month, the stock market plummeted, the Yan family went bankrupt, Yan Shiqing couldn't afford to get sick, and he swallowed his breath within two years, leaving the pair of orphans and widows to suffer in the world.

At the beginning, I didn't want to think about the consequences of failing to speculate in stocks, so I got into it headlong, if it was just a little pocket money, I would lose it, and I wouldn't end up like this; made Li Zhi faint, hurt himself and hurt his family.

-------------------

Ling Shizhe has a very leisurely life, these days have been going around between the three women, today he stayed at Li Li's house, tomorrow he will be at Yan Xiaoyun's house, and the day after tomorrow will be at Zhao Xiaoyun's house, so don't live too comfortably.

The new beauty did make him happy, but what made him even happier was the news from Canada that there had been new progress in the research and development of blade servers, and Nien and they finally succeeded in making the world's first solid-state drive the day before yesterday after months of hard work.

The hard disk is composed of 8 flash memory chips, a main control chip, and a cache chip; Nandflash flash memory chip belongs to MLC flash memory, and the storage capacity of a flash memory chip is 2M.

In later generations, NAND flash memory chips are generally divided into SLC (single-layer cell), MLC (multi-layer cell) and TLC (three-layer cell) NAND flash memory.

MLC flash is the most widely used flash memory technology in solid-state drives, MLC stands for multi-tier storage, and its biggest feature is that higher storage density is exchanged for lower storage costs, so as to obtain the opportunity to enter more terminal fields. However, the disadvantages of MLC are also obvious, its write life is shorter, and the ability to read and write is also lower than that of SLC, and the official number of rewrite times is only 10,000 times, but it is generally 3000-10000 times.

Don't look at its erase and write life, but Ling Shizhe can greatly improve the life of the storage unit through the management of the storage unit through the equalization algorithm.

A complete erase of flash memory is called 1 p/e, so the life of flash memory is measured in p/e. For example, a 34nm flash memory chip has a lifetime of about 5,000 p/e, while a 25nm memory chip has a lifetime of about 3,000 p/e.

Through the management of the storage unit by the equalization algorithm, the amount of unnecessary writes can be reduced; For example, a 120G SSD in the future will only be counted as a P/E if a 120G file is written. Ordinary users use normally, even if they write 50G a day, an average of 2 days to complete P/E, 3000 P/E can be used for 20 years, by that time, SSDs have long been replaced with more advanced equipment.

Therefore, in the SSD, the accusation chip is a key indicator, which is the brain of the SSD, and its role is, first, to reasonably allocate the load of data on each flash memory chip; The second is to undertake the entire data relay, connecting the flash memory chip and the external SATA interface. There is a big difference in the ability between different main controllers, and there will be great differences in the data processing capabilities and algorithms, and the read and write control of the flash memory chip, which will directly lead to a big gap in the performance of SSD products.

In short, a good main control chip can not only greatly improve the read and write speed of data, reduce data read and write errors, but also greatly increase the service life and capacity of the SSD.

In addition, caching can also greatly improve the performance of SSDs, and there are some cheap SSD solutions on the market in later generations that save costs by omitting this cache chip, which will have a great impact on the performance of hard drives.

In the report sent by Nion, the SSD is to be used as a hard disk for the blade server, and it has extremely high requirements for stability and reliability, so he used 2 cache chips for this SSD to improve the performance of the hard disk and the accuracy of data reading and writing; In addition, Nien plans to optimize and improve the algorithm of the data again, so that the performance of the main control chip will become better, and a main control chip is completely sufficient, and there is no need to add it in addition.

A single NandFlash flash chip has a capacity of 2m and uses 9 micron process technology, but Nien has found a new way to increase the density of flash memory particles on the same micron process technology to greatly increase the capacity of flash memory chips.

Nien's report reminded Ling Shizhe of the SSD capacity dispute between Samsung and Toshiba in later generations; At that time, Toshiba's SSD Nandflash flash memory chip used a 90nm process, while Samsung used a 74nm process to produce Nandflash flash memory chips, which put Toshiba at an absolute disadvantage in the competition of SSDs; If you want to upgrade the 90nm chip production line to the 74nm production line, in addition to spending a lot of money, it will definitely be too late in time, what should you do?

At this time, Kazuo Kojima, a scientist at Toshiba, proposed to increase the density of flash memory particles to increase the capacity, and the entire Toshiba company did not believe in this proposal.

You know, at that time, there was only one way to increase the capacity of flash memory chips, that is, to improve the process of chips, such as from 90 nm to 74 nm, which was the most effective way.

But the young Kazuo Kojima does not see it that way, he believes that improving the manufacturing degree of the flash memory process can certainly improve the capacity of the flash memory chip, but it is not the only one, under the same manufacturing process, increasing the density of flash memory particles can also increase the capacity of flash memory.

The denunciation from the top makes it difficult for Kazuo Kojima to move forward in the company, and he has to face the ridicule of his colleagues around him every day, and his life is underestimated.

Kazuo Kojima was not discouraged, completely ignoring the strange stares and mockery of his colleagues, but carried out more in-depth research on flash memory chips. Finally, three months later, Kazuo Kojima successfully achieved high-density flash memory particle integration on the flash memory chip of the 90nm process, and the flash memory particle density is 10% higher than the flash memory particle density of Samsung's 74nm flash memory chip, and the capacity of the flash memory has been nearly doubled, which shocked the world.

Not to mention how Kazuo Kojima raised his eyebrows and was ashamed, Toshiba soon launched a new 90nm flash memory chip SSD, like a hurricane swept the market, Samsung's SSD market to the ground, and finally Samsung could only go to the Chinese market to seek comfort.

At that time, the battle for the SSD market was quite famous, and the two sides fought quite fiercely, and finally ended in Toshiba's complete victory, which made Ling Shizhe remember Kazuo Kojima, and remember the relationship between flash particle density and capacity.

Ling Shizhe never imagined that in order to solve the problem of too small and too large the capacity of mechanical hard disks in this era, and the solid-state drive technology that was taken out decades in advance, Nion's research team would discover the relationship between the secret of flash memory particles and capacity so quickly, which greatly surprised him.

You know, the world's first solid-state drive was born in 1989.

In March 2006, Samsung took the lead in releasing a 32GB capacity SSD notebook, and SSD officially entered commercial application.

In 2009, Kazuo Kojima discovered the relationship between the density and capacity of flash memory particles, this year was a watershed in SSD technology, Kazuo Kojima's discovery greatly reduced the manufacturing cost of SSD, and since then SSD has begun to develop exponentially and enter the homes of ordinary people.

Cow, too good, Ling Shizhe remembers very clearly, when he told Nien about SSD technology, he didn't tell him the relationship between particle density and capacity, but he didn't expect Nien's team to find out by himself.

He directly ignored the relationship between the time difference between Hong Kong and Canada, and called Nion, who was still asleep, with a phone call, and asked him directly who discovered the relationship between density and capacity.

was woken up in the middle of the night, Nien was very angry, but as soon as he heard that it was Ling Shizhe who called, he immediately put out the fire, who called him a part-time worker, he could only tell him honestly that it was two Chinese scientists, one named Fu Yushan and the other Tang Haiguang, who were discovered by the two of them at the same time.

Reward, reward, Ling Shizhe's voice on the phone was very firm, not only to reward heavily, but also to promote the two of them, to promote Tang Haiguang to the general deputy head of the SSD laboratory, the highest person in charge is Nien, after Tang Haiguang got started, after taking over Nien's position, Nien was liberated, and in the past few months, Nien had to manage the North American laboratory, the RISC laboratory, and the SSD laboratory, and he was tired enough, so he took this opportunity to simply liberate Nien.

Unfortunately, this era is the early stage of the development of semiconductor technology, those engaged in semiconductor research are young people, this age is the golden age of scientific research results, only a very few people are willing to do the management of semiconductor laboratories, the managers of semiconductor laboratories are not so easy to find, he is much more demanding than general enterprise managers, not only to understand management experience, but also to understand semiconductor technology, otherwise you can't manage at all.

Don't look at those scientists are weak scholars, but they are all arrogant roosters, and they are not convinced by anyone, and if the managers of the laboratory do not have high enough prestige or qualifications, or they can't be pressed academically, hehe, you can bear it.

Wasn't that the case with Glover, the former president of Intel? If it weren't for the fact that he was the first employee of Intel and Robert Noyce and Gordon Moore supported him, Grove would have been knocked down by those arrogant scientists, and it was with this experience as a laboratory manager that Andy Grove would later become the third president of Intel.

Different from the previous two managers, Andy Grove's management methods are quite iron-fisted, and he is the most famous iron-blooded prime minister in the history of Intel, which is most directly related to his experience as the head of the Intel laboratory at that time.

In later generations, semiconductor laboratories are managed by a group of elderly scientists, in addition to their own experience in enterprise management, they have also passed the golden stage of scientific research results, and they can not produce any results when they are older, so it is the best choice for them to start transferring to the management of the laboratory.

Don't think that in Western companies, people don't pay attention to qualifications, qualifications are also one of the most important indicators for business managers, sometimes the requirements for seniority are higher than those in China, and they are more demanding.

In North America, from the establishment of the laboratory to the present, there are more than 1,000 scientists, but the management leaders of the laboratories are very rare, they are either pure scientists who do not know anything about management and cannot take on management work, or scientists who know how to manage but are unwilling to do laboratory management, because their age is just stuck in the golden stage of scientific research results, who wants to come? No one wanted to come, so many times Nien had to wear many hats, and he had to give up his scientific work in order to keep the lab running.

Tang Haiguang is less than 40 years old, very young and officially out of the golden age of scientific research results, for scientific research, he prefers to engage in management work, although he is Chinese, but everyone is convinced of him, it is appropriate to put him up to share the management burden of Ninn, and Fu Yushan was promoted to the head of the flash memory research and development team, and at the same time served as the deputy director of the SSD laboratory, as Tang Haiguang's assistant, he is not afraid that no one will be convinced, this scientific discovery is enough for Fu Yushan to gain a firm foothold in the laboratory, and bring him up, No one will object; As for racial discrimination, the glass ceiling? Come on, the boss of Ambrera is Chinese, you still dare to have an opinion, beware of killing you x.

After arranging the two of them, Ling Shizhe listened to Nion's report again, the current packaging technology for flash memory chips is still using ceramic packaging technology, and they are now starting to study plastic packaging to meet the requirements of low-cost and large-scale commercial production.

Chip packaging technology is one of the most important technical processes of semiconductor chips, without which the chip can not be put into use, chip packaging is divided into three stages in history, the first stage is metal packaging, this packaging technology is the most primitive packaging technology, its cost is quite high, in later generations he will only be used in military and aerospace technology, but in the sixties and seventies, metal packaging and is the mainstream of chip packaging.

The new packaging technology developed after the metal packaging is ceramic packaging technology, the C4004CPU launched by Intel company in history is the first ceramic packaging technology to be adopted, compared with metal packaging, the price of ceramic packaging technology is relatively low, with good reliability, plasticity, and good sealing, with high insulation performance and excellent high-frequency characteristics, its linear expansion coefficient is very similar to electronic components.

Compared with plastic packaging technology, ceramic packaging technology is still high in cost, but ceramic packaging is still irreplaceable in many uses, especially the increase in the working frequency of integrated circuit components, the acceleration of signal transmission speed and the increase of chip power consumption, the need to choose low resistivity wiring conductor materials, low dielectric constant, high conductivity insulation materials, etc., so ceramic packaging has a wide range of applications in aerospace, military and university computers.

The CPU used on the blade server designed by Ling Shizhe is an RMP series CPU, which uses ceramic packaging technology, and the blade server is a typical low-cost, high-density computing server, with a blade on the CPU standard configuration alone is as many as 8, and the maximum number of CPUs is 56, in addition, he also added 2 GPUs to the motherboard, so many CPUs are integrated on a board, how much heat dissipation can be imagined, with plastic packaging? It's no wonder if you don't burn it, not to mention that using ceramic packaging can also greatly improve the stability of the CPU, which is a better material for blade computers.

Even the CPUs used in PC computers are not all made of plastic packaging technology, it is only a partial replacement, such as the famous i7CPU.

After talking about ceramic packaging, the next is plastic packaging, compared with the previous packaging technology, it is quite cheap, cost-effective, simple process, very suitable for mass production, in the 21st century, tens of billions of chips produced every year, the use of plastic packaging chips accounted for 90%.

In order to increase the capacity of the solid-state drive, Nien told him that the two scientists also thought of the 3D packaging technology that appeared in later generations, this 3D packaging technology uses stacking technology, that is, stacking multiple bare chips and even wafers into interconnection, packaged in a chip, forming a three-dimensional package, the wafer should be cut thin enough, people can't see at all, a chip is equipped with several bare chips, and when running, several pieces of the chip are stacked into interconnected chips for parallel operation. This method can increase the chip capacity of the flash memory chip several times under the same volume, which not only saves space but also improves the capacity of the flash memory, which is a very good packaging technology solution.

Khan, they all thought of this method, Ling Shizhe almost thought that he had met the traverser, in the later generations that the chip did not do this, even the i7CPU did this, which greatly improved the CPU performance, when they heard that they proposed this method, Ling Shizhe immediately told Nien, if this method works, you can try it on other chips, such as on the CPU, to see if there is any improvement in performance, if the effect is obvious, see how much it costs to do this, if the cost is not very high, Just make a batch and put it on the market to see, and it will be mass-produced.

Another good news is that the kernel design of the graphics operating system of the blade server has been fully completed and has entered into full testing, and if there are no problems, the graphics operating system will be fully developed.

Put down the phone, this is the best news Ling Shizhe has heard, finally it's not all bad news, blade servers, no, it should become a blade supercomputer, most of the blade servers in later generations are network servers, there is no network in this era, the only direction of the blade server can only go to the road of supercomputers, as long as this computer is successfully developed, it will be a tsunami for the supercomputers of this era, completely drowning them, how much is the computing speed? 500 million, 1 billion, 5 billion or 10 billion?

I don't know, Ling Shizhe doesn't know at all, in theory, as long as there are enough units, he will improve infinitely, but in fact, it still has a limit, but what the limit is, only the final test will be known.

Sitting on the office chair, Ling Shizhe drank coffee, thinking about whether he needed to take out the cloud computing technology in advance, so that the computing speed of the supercomputer could be improved again on this basis, as long as the supercomputer was made, Ambrera would completely establish the position of the leader in the computer industry, and form a serious impact on IBM.

Well, when the blade server-related technology is still open, you only sell CPU and operating system, this thing is too strong, it is very dangerous to eat alone, after opening, see if IBM will join the blade camp, join the best, if you don't join, it's none of my business, you don't join, some people join, when the time comes, you will be angry and angry, and the anger will not spread on me, you will fight slowly with the world's computer manufacturers, I will follow to make money, I like it the most.
