Now the flash memory particles with the largest capacity can reach 8mb single particles. In theory, a thumb-sized USB flash drive can be stuffed into two or even four particles, but the price is also increasing in proportion.

Currently, Nand particles are mainly produced in Intel and Micron, and are extremely expensive. Most of the application scenarios are used in places where disk reading speed is required, so they are generally regarded as the core storage medium of "high-end hard disks".

As for USB drive, this device that is obviously created to replace floppy disks, has nailed its popularity by just one cost.

Therefore, Jiang Tao was very depressed...

...

"I have completed the craft this time. I'm afraid that the happiest person is Senior Brother Jiang Tao?" Su Yuanshan asked with a smile.

"Well, but he suffered a loss last time. Now he is a bitten by a snake and is afraid of the well rope for ten years." Li Mingliu also smiled: "And their finances are already independent, without Zhongxin's blood transfusions, and his life has not been very good recently - why don't you buy him?"

"Uh... forget it, how can you get the seniority level?"

Jiang Tao’s Yuanzhong Microelectronics is a wholly-owned subsidiary of Zhongxin, Zhongxin is also a joint venture of Yuanxin, and then Jiang Tao is the earliest employee of Yuanxin... If this is taken over... let’s not talk about the share issue, it is difficult to discuss this generation alone.

Moreover, Su Yuanshan also hopes that more excellent professional chip design companies can emerge in his bones. He does not engage in Concen Trust, so there is no need to attribute all teams to Yuanxin.

"Then you have to cheer him up. I saw that he was anxious recently." Li Mingliu smiled: "At the time they used control chips with us, they thought they could open up a brand new market and win a red ocean. Now they are ruthlessly ravaged by reality... If you don't care about him, I think he will argue with you."

Su Yuanshan was silent.

But...think about it, it's really the case - Jiang Tao and Li Mingliu were very clear at the beginning, and they were research and development under Su Yuanshan's arrangement. Now Jiang Tao's achievements have come out, but the market does not accept them.

If Su Yuanshan doesn't care, it will definitely be unreasonable.

"It's okay, wait for the Nand chip of the mlc architecture to get off the line, and the USB drive will take off immediately!"

"Well, I said that too."

...

As Li Mingliu returned to the Science and Technology Park, Su Yuanshan did not go to the wafer fab immediately, but went to the design center to cheer everyone up. Then he was blocked in Li Mingliu's office by Jiang Tao who heard the news.

It can be seen that Senior Brother Jiang is indeed a little anxious recently.

"Xiaoshan." Seeing that there were only Su Yuanshan and Li Mingliu in the office, Jiang Tao closed the door directly and said anxiously: "You said that USB flash drive was just like you were about to be killed by floppy disks or even CDs. Now... We have been working on it for more than a year..."

"Senior brother, don't worry. Didn't I say that I need to cooperate with multi-layer architecture flash memory chips to be cost-effective? And who asked you to buy so many single-layer SLC particles? You don't know about Intel's things, it's expensive..."

"...I didn't listen to you, do you think of this thing..." Jiang Tao looked helpless: "It's been a month since then. In addition to buying some of the peers and then giving some, some of them were given. Some big computer stores took them as treasures in the store, and they couldn't sell them at all. And some of them were also scrambling for patents with us... claiming that they also invented flash drives based on the USB interface."

"Well, it's okay." Su Yuanshan smiled and comforted: "When the mlc particles come out here, the cost will be reduced in an instant - right? Old Li?"

Li Mingliu nodded: "This time, the architecture of de-filtering is still adopted by the 2D architecture, but even so, the capacity cost per unit wafer area has been reduced by half. When the process of the 3D architecture is mature, you can pile as much as you want."

Jiang Tao was stunned when he heard this!

In the past year or so, he has been working with Li Mingliu's team in various ways, and he also knows that after Li Mingliu and his team have completed the mlc architecture, they have been working towards multi-layer stacking.

If you take a room as an example, Intel's current SLC particles are a separate room, living in one person. Then mlC particles divide the room into two single rooms, living in two people.

The so-called 2d architecture means that the house is a bungalow. The 3d architecture means that it is a building - it can be stacked infinitely.

If that is true, now a piece of SLC flash memory particles that are only 8mb at most may reach 128mb, 512mb or even more in the future - as long as the process and technology can keep up!

Now, following what Li Mingliu meant, has he done the 3D architecture?

"Is it done?" Jiang Tao asked tentatively.

Li Mingliu smiled, but did not give an accurate positive answer: "Now, the de-filtering architecture is used, because the process uses the most advanced 0.5 microns, so the capacity can be 32mb per piece of particles - but the cost is only a little more expensive than Intel's."

Jiang Tao jumped up suddenly: "Damn it! Wouldn't that take off directly?"

"Then next year...if everything goes well, maybe a single piece of pellet can reach 64mb, or more."

...

...

Watching Jiang Tao leave happily, Su Yuanshan and Li Mingliu couldn't help but smile and shake their heads.

It can be seen that without Zhongxin's blood transfusion, Yuanzhong Microelectronics... it is indeed a long way to go.

Of course, Yuanzhong Microelectronics has been pressing on USB flash drive, which objectively put them under a lot of pressure. Now that they hear that the cost of USB flash drive can drop exponentially, Jiang Tao will naturally be happy.

But... he forgot that in order to promote a new device with a new interface, in addition to the price, he also needs conceptual publicity.

"Tell me, how to solve the main difficulties of 3D architecture."

Su Yuanshan put away his smile and turned to be serious.

——This is his real purpose for coming here.

As the boss of Yuanxin, he can only focus on the results, but as an engineer, he must pay attention to specific technical implementations.

Li Mingliu is a genius in the field of integrated circuit design, which is an unquestionable fact.

But Su Yuanshan was still very curious about how he solved various problems in multi-layer architecture.

Because even Su Yuanshan doesn’t know how to implement a multi-layer architecture in the field of flash memory chip design.

He is a CPU, and he only knows how to use the Finfet architecture.

"In fact, the logic is very simple, and the main thing is to implement the technology." Li Mingliu opened the notebook and began to explain to Su Yuanshan.
