The world's richest man started by developing gutter oil

[This week’s product: Universal Flash Storage complete set of technology, priced at 2 million RMB. 】

[Introduction: Universal Flash Storage is a storage system that encapsulates Nand Flash and Flash controller protocol interfaces. 】

The abbreviation of Universal Flash Storage is USF memory. This technology will directly replace eMMC memory in later generations, because USF memory far exceeds eMMC memory in terms of reading and writing speed.

Before Chang Sun Xiaoxiao could react, Han Chen picked up the opponent and pinned him down with his backhand.

"No." Changsun Xiaoxiao looked at Han Chen in horror and said in a hoarse voice.

But Han Chen didn't pay attention to her request. Without saying a word, Han Chen took out his machete and slashed directly at the intestines.

Although Changsun Xiaoxiao resisted hard, his body was very honest. With a "嘤咛" the battle started again.

It’s twelve o’clock in the blink of an eye.

Han Chen got up from the bed and looked at his eldest grandson, Xiaoxiao, who was sleeping like a baby on the bed and smiled crookedly.

Then Han Chen took out a genetic optimization capsule from the system and fed it to her mouth.

I don’t know if a conditioned reaction has already formed, but Changsun Xiaoxiao swallowed the gene capsule. Han Chen came to the tea table after feeding the capsule.

After Han Chen turned on the computer, he found a folder called Universal Flash Storage in the computer.

Han Chen skipped UFS 1.0 and directly clicked on the UFS 2.1 folder.

There is not much difference in performance between UFS 1.0, so Han Chen plans to go directly to UFS 2.1. Han Chen opens the file and starts looking at related technical introductions. Han Chen will use UFS 2.1 in the next generation of products.

UFS consists of a total of 5 structures.

1.UFS main control chip.

Mainly responsible for managing and controlling the memory chip in the card and data transmission and communication with the host device.

2. Flash controller.

The memory controller is the core component in the UFS chip and is responsible for managing and controlling memory read and write operations. It receives instructions from the host device, parses and executes these instructions, and manages the caching and transfer of data.

3. Send and receive ports.

These interface circuits are responsible for communicating with the host device, processing and adjusting data transmission rates and electrical signals.

4. Controller processor.

Some more advanced UFS chips may integrate a controller processor to perform more complex storage control and management functions. These processors assist the memory controller with tasks such as error detection and correction, data compression, and encryption.

5. Flash memory chip.

The flash memory chip in the UFS chip is the part used to actually store data. It is usually manufactured based on NAND Flash technology and has fast data transmission speed and large storage capacity.

6. Housing and connectors.

UFS cards usually come with a sturdy casing and suitable connectors to provide protection and easy plug-in interface.

Han Chen did not expect that the actual structure of USF memory was so complicated, but USF brought an unexpected surprise to Han Chen, because UFS technology includes 3D NAND Flash technology.

To put it simply, USF is a memory that packages NAND Flash and chips together through SOC. Its structure is relatively more complex than traditional NAND Flash.

If NAND Flash is simply manufactured, NAND Flash masks will be very cheap, because NAND Flash masks are very easy to manufacture. Once NAND Flash is integrated with the main control chip, their mask manufacturing costs will become very high.

Moreover, the research and development cost of integrating the two is higher than that of simply developing main control chips or pure NAND Flash.

You must know that 3D NAND Flash technology is not even available to giants such as Shanxing, Micron, Hynix and Infintech.

3D NAND Flash technology also includes three basic unit technologies: SLC/MLC/TLC.

The basic unit of Flash is a floating-gate transistor, whose state can be used to indicate binary 0 or 1.

The write operation is to inject electrons into the transistor to charge it; the erase operation is to expel the electrons in the transistor to discharge it.

Since this is an analog system, the transistor does not have an absolute empty or full state. The number of electrons in the transistor can be in any state between empty and full.

由此可见，可以根据晶体管中电子的数目来指示二进制的0和1。比如在SLC（Single Level Cell）中，晶体管中电子数目小于50%的时候代表1，大于50%的时候代表0。

SLC is a first-order quantization of the number of electrons, so a transistor can represent two states: 0 and 1.

如果我们对晶体管中的电子数目做二阶量化，一个晶体管就可以代表四个状态：少于25%代表00，25%~ 50%代表01，50%~ 75%代表10、大于75%代表11。这就是MCL(Multi Level Cell)的做法。

当然我们还可以对晶体管中的电子数目做三阶量化，一个晶体管就可以代表八个状态：000、001、010、011、100、101、110、111。这是TLC(Three Level Cell)的做法。

In other words, the higher the quantization level, the more states a transistor can represent, the greater the storage density, and the greater the storage capacity of a storage medium composed of the same number of storage units.

Moreover, the NAND Flash technology here also bypasses the existing patent barriers of major memory manufacturers.

This was undoubtedly a big surprise for Han Chen.

After reading the technical introduction, Han Chen began to write a patent application for UFS memory. After submitting the patent, Deep Blue could contact SMIC for chip production.

9 pm.

The mobile phone on the bedside table kept ringing.

Han Chen, who was still sleeping, was woken up by his cell phone.

After Han Chen woke up, he gently pushed away the eldest grandson Xiaoxiao who was sleeping soundly on his chest. The eldest grandson Xiaoxiao didn't get out of bed all day. Han Chen even fed her dinner.

It wasn't that she didn't want to move, but that she had no strength at all. She felt like her bones were falling apart after being tossed around like this by Han Chen.

After Han Chen taught her this lesson, she was really scared. Now she no longer dared to provoke Han Chen. She also realized the importance of having sisters.

Everyone says that there are only exhausted cows and no damaged fields, but Han Chen is an exception. Han Chen has no way to use common sense to understand Han Chen. If you have to use common sense to understand Han Chen, there is only one idiom that can do it. To describe Han Chen, this idiom must be that he is gifted.

Changsun Xiaoxiao bets that even Zhao Ji's Lao Ai is not as powerful as Han Chen.

[Caller: Wu Qimin]

"Old Wu, what's the matter with calling me?" Han Chen picked up the phone and took a look before answering.

"Mr. Han, the matter is about Zhifubao. Zhifubao has launched a scan-and-scan payment function. Scan-and-scan infringes our patent. I have asked lawyer Lei to send them a lawyer's letter, but I plan to tell you again. One sound." Wu Qimin said.

At this moment, Zhang Sun Xiaoxiao turned over again and hugged Han Chen's body tightly.

"If they ignore it and continue to use it, let Uncle Lei sue them directly." Han Chen said.

The key to offline payment on the payment platform is to scan this function. Fortunately, Han Chen registered this patent in advance. As long as Zhifubao cannot use this patent, no matter how awesome Zhifubao is, it will not be able to surpass Deep Blue.

Of course, they can also choose to use NFC to pay. NFC is as convenient as scanning QR codes, but if they want to use NFC to enter the market, they have to face a very serious problem. That is, every mobile phone must be equipped with NFC function, but only mid-to-high-end mobile phones will be equipped with NFC. If Zhifubao wants manufacturers to equip NFC, then Alipay must pay for the NFC chip.

You must know that the current price of NFC chips is very expensive. The price of an NFC chip is about 100 soft sister coins.

It will not be until 2015 that the price of NFC chips drops to about $2.

Zhifubao has no ability to bear this cost. Even if Alipay develops its own NFC chip, it will take at least two years to implement it. Two years later, Deep Blue has occupied more than 80% of the payment market.

"Okay, Mr. Han, I don't have anything else to do here, so I won't disturb your rest," Wu Qimin said.

"Okay." Han Chen replied.

Han Chen put down his cell phone and was about to continue sleeping with Nephrite in his arms when his cell phone rang again.

[Caller: Tang Huixiang]

"Mr. Han." Tang Huixiang greeted.

"What's the matter?" Han Chen asked.

"Mr. Han, the Chinese person in charge of Fruit called yesterday. They want to obtain the facial recognition patent from us. How do you think this matter should be handled?" Tang Huixiang asked.

"The technology department authorizes us to only provide facial recognition chips. The price of a single chip is set at 25 US dollars. If they need it, tell them that it will be available in six months. If they need it, send me an email and I will We arranged for Deep Blue Semiconductor to produce it.

If other mobile phone manufacturers contact you and want to obtain authorization, please quote them the same price of $25. Other product manufacturers should not authorize it. If the other party has a special identity, please contact me again.

In addition, each purchase contract cannot exceed 1000 million pieces, and each contract can only be signed for 1000 million pieces. "Han Chen said.

Han Chen knew that even if the Deep Blue mobile phone had facial recognition technology, it would only be more advanced than the fruit.

It does not mean that facial recognition on Deep Blue mobile phones can replace fruits. Users who should buy fruits will still buy fruits, but the money delivered to their door must be earned. This will not only accumulate original capital for Deep Blue, but also enable it to Facial recognition technology has spread to the market.

The more manufacturers that use Deep Blue technology, the higher the voice Deep Blue will have in the field of electronic products.

In addition, Han Chen's other purpose is to make those manufacturers become dependent on Deep Blue, so that these manufacturers will form an idea that making is worse than buying. Once these manufacturers have this idea, Deep Blue will become the leader in a certain technical field. .

Only in this way can Deep Blue stand firm in the market.

"Okay, Mr. Han, if there's nothing else, I won't disturb your rest," Tang Huixiang said.

"Okay." Han Chen said and hung up the phone.

September 2010, 7, China time.

11: am.

Shanxing Building, Chaoyang District, Beijing.

After some contact, Wu Manjiang finally contacted Rong Zhengli of Deep Blue Semiconductor.

"Hello, Mr. Rong, I am Wu Manjiang, the operations director of Shanxing Huaxia Region." Wu Manjiang reported his family background.

"Hello, Mr. Wu, what can I do for you?" Rong Zhengli asked.

Currently, Deep Blue Semiconductor does not conduct external sales, so Rong Zhengli was curious as to why the other party contacted him.

"Mr. Rong, we Shanxing want to obtain facial recognition technology authorization from you. I don't know if your company licenses facial recognition technology to external parties." Wu Manjiang asked.

"Mr. Wu, the facial recognition technology patent does not belong to Deep Blue Semiconductor. This technology is owned by another subsidiary of our group. However, I will give you a contact information. You can contact the other party to see if it can be authorized to you." Rong Zhengli said.

Shanxing is not the first company to contact him, but the facial recognition patent belongs to Deep Blue Security.

Therefore, it is not easy for him to make decisions for Tang Huixiang regarding facial recognition.

"Mr. Rong, please tell me the contact information of the other party." Wu Manjiang said.

"Mr. Wu, please take your notes, 138XXX" Rong Zhengli reported Tang Huixiang's phone number.

Wu Manjiang took down Tang Huixiang's phone number and said thank you to Rong Zhengli before hanging up the phone.

"~Du~Du~Du~"

After hanging up the phone from Rong Zhengli, Wu Manjiang immediately called Tang Huixiang.

"Hello, who is this?" Tang Huixiang asked after answering the phone.

"Hello, Mr. Rong, I am Wu Manjiang, the operations director of Shanxing Huaxia Region." Wu Manjiang reported his family background.

"Hello, Mr. Wu, what can I do for you?" Tang Huixiang asked.

"Mr. Rong, we Shanxing want to obtain facial recognition technology authorization from you. I don't know if your company licenses 3D facial recognition technology." Wu Manjiang asked.

"Mr. Wu, I'm sorry that we do not license facial recognition technology to external parties. We only sell chips that can perform facial recognition. The price of a single chip is US$25 a piece." Tang Huixiang said.

Wu Manjiang gasped when he heard the price was 25 US dollars a piece.

You should know that the CPU chip used in smartphones only costs US$16-18. Deep Blue actually sells the facial recognition chip for US$25, which is far beyond their expected price.

"Mr. Tang, can't the price be cheaper?" Wu Manjiang asked.

"Mr. Wu, given the R&D costs, it's difficult for us to lower the price. We sell fruits at the same price," Tang Huixiang said.

"Have you reached an agreement with Fruit?" Wu Manjiang asked as if he had heard some great news.

"Ah, fruit? Mr. Wu, did you hear it wrong? I said I sold it to other people for the same price." Tang Huixiang pretended to be surprised.

In fact, Tang Huixiang hasn't even quoted a price for the fruit yet. She understands why she did this. The purpose was to create some pressure on Shanxing.

All fruit phones will use face recognition technology, don’t you Shanxing use it?

"Oh, I heard it wrong." Wu Manjiang laughed.

Of course, Wu Manjiang is not a novice. He also saw through Tang Huixiang's tricks. The game between the two parties begins here.

"I wonder if Mr. Wu is interested in our identification chip?" Tang Huixiang asked with a smile.

"Can't it be cheaper if we purchase 10 million pills at a time?" Wu Manjiang asked seriously.

"Mr. Wu, even if you purchase 100 million pills, there is no way to make it cheaper, because this price is set by our chairman." Tang Huixiang said.

"I need to report this to my superiors. I will contact you, Mr. Tang, later," Wu Manjiang said.

"Okay." Tang Huixiang replied. (End of chapter)
