Technology: Start by selling mobile phones

"Mr. Mo, in the past few months, we have been thinking of ways to improve the yield rate of '3D-NAND' flash memory particles, and finally..."

"After spending a lot of money and countless improvements, the last improvement yesterday finally increased the yield rate of 32-layer '3D-NAND' flash memory particles to 42%. From a cost perspective, it has initially reached the mass production level. standard."

42%.

Has it initially reached mass production standards?

Hearing the news, Mo Ran was immediately overjoyed, with a hint of surprise on his face.

This is indeed great news for the 32-layer "3D-NAND" flash memory particle project that has always required a large amount of capital investment.

Immediately afterwards, Li Zhi added:

"Initially, the yield rate of our '3D-NAND' flash memory particles was only 19%. Four months ago, it increased to 28%, and now it has finally increased to 42%!"

"Although according to the rules of the chip industry, the general yield rate must reach more than 65% before small-scale mass production can be carried out, but..."

"Compared with traditional '2D-NAND' flash memory particles, the advantage of our '3D-NAND' flash memory particles lies in cost. Especially for 'flash memory particles' with large storage capacity, the cost advantage of '3D-NAND' is even greater. obvious."

"On the other hand, it can be said that we have benefited from the recent increase in the price of 'flash memory particles' in the market. Even though we only have a 42% yield rate, the cost after conversion is almost the same as the price of traditional 'flash memory particles' in the market. So, I said From a cost perspective, it has reached mass production standards.”

So that's it.

Li Zhi's explanation made Mo Ran completely enlightened.

The advantage of "3D-NAND" technology is that it can manufacture more storage units on a wafer with the same unit volume, thereby achieving greater storage capacity.

This is just like before, only 64GB wafers could be produced. Now using "3D-NAND" technology, 128GB or even 256GB capacity can be produced.

Even if the complexity of "3D-NAND" technology leads to an increase in production costs, there is no doubt that the price per GB will definitely decrease.

Now that the yield rate of 32-layer "3D-NAND" particles has increased, the advantages of 3D technology have gradually become apparent.

Thinking of this, Mo Ran patted Li Zhi on the shoulder and praised:

"Well done."

"so far so good……"

Li Zhi smiled modestly, waved his hand and said:

"Actually, I just did some simple work. The main credit is due to Zheng Qianhe and the production department. They have put in a lot of effort in the past few months. It is indeed too hard."

As soon as he said this, Mo Ran couldn't help but smile.

Compared with the low-key and pragmatic attitude of Mr. Li from "Wanglong Electrical Appliance Factory", Li Zhi can clearly feel the frankness and sincerity of young people from the heart, without so many other twists and turns.

This is why even though Li Zhi is young and has insufficient qualifications, Mo Ran still asked him to be the CEO of "Yellow River Storage".

Fairness, magnanimity, and the ambition of young people can give the greatest fairness to all department personnel!

Mo Ran's eyes became more affirmative.

"In any case, as the person in charge of the Yellow River Storage, you must have contributed to the research and development results."

"Don't worry, I will remember these, and there will definitely be rewards when the time comes."

Li Zhi was no longer polite and nodded repeatedly.

"Then thank you, Mr. Mo."

After saying this, Li Zhi did not continue to struggle with this topic. After a while, he continued the previous topic.

"Then Mr. Mo... are our 32-layer '3D-NAND' flash memory particles officially ready to start mass production?"

"Okay, we can start on this matter."

Mo Ran didn't hesitate and immediately agreed.

The time is now ripe. The cost of purchased traditional "2D-NAND" flash memory particles and the "3D-NAND" flash memory particles produced at home are almost the same. It is also time to try mass production substitution.

Moreover, once the production capacity catches up and the subsequent yield rate increases, "Yellow River Storage" can also sell its own "3D-NAND" flash memory particles, and then it will really get on the right track.

"Then there's one last question."

"We are about to mass-produce 32-layer '3D-NAND' flash memory particles. Mr. Mo, do you think we should publicize this to the outside world?"

"With traditional '2D-NAND', we are indeed unable to match the decades of technology accumulation of foreign manufacturers, but in the brand new track of '3D-NAND', our 'Yellow River Storage' can be considered a first-tier manufacturer from a global perspective, and in China We are the only manufacturer that can produce '3D-NAND' flash memory particles!"

"Especially now that domestic public opinion..."

After saying that, Li Zhi paused.

"Especially after the Huawei incident, domestic public opinion is now supporting domestic products. If we don't say anything else, as long as we promote the 'domestic 3D-NAND' flash memory particles, the sales of our 'Jinghong Series' TF memory cards will definitely be particularly hot."

"Look..."

This time after the words fell, Mo Ran did not directly agree as before, but fell into a long silence.

After a few minutes, he suddenly shook his head.

"This matter is not publicized and there is no rush."

"No publicity?!"

Mo Ran could see the surprise on Li Zhi's face, and after a brief pause he said:

"I just want to ask you something. If Samsung and Hynix immediately lower the price of flash memory particles after the news that we can produce 32-layer '3D-NAND' particles is announced, what will we do?!"

"If I don't say too much, how can we compete if the price is reduced by 15%?"

Li Zhi's face was stunned for a moment before he reacted.

Yes, our own 32-layer flash memory chips with a yield rate of 42% are barely on par with the market price despite the current high prices.

Once the price of flash memory particles suddenly drops, our own 32-layer flash memory particles will have no price advantage. Let alone selling them to other manufacturers, I am afraid that even the "Jinghong series" memory cards will have to consider whether to replace them with lower-cost traditional 2D flash memory particles. .

"In addition, our 32-layer flash memory particles have just started mass production, and the production capacity is still in the climbing stage, so it is easy to run out of capacity."

"It just so happens that our 'Jinghong series' memory cards are selling well right now. We can replace them with the 'Jinghong series' first. We can even try to replace the 'flash memory particles' in our Nietzsche mobile phones."

Li Zhi completely understood what Mo Ran meant - not to make it public first, but to supply it internally for his own use first!

After a moment, he nodded vigorously.

"Okay, Mr. Mo, I understand."

Mo Ran showed a smile. In fact, apart from the reasons he said, there was a more important reason in his heart.

Since the last time Jiang Lan revealed more about "Pony Crossing the River" at a press conference, which caused a huge heated discussion, he was worried that he would be noticed by Americans, so he has been trying to reduce Nietzsche's popularity.

Seeing that the popularity has gradually dropped in the past few days, now another "3D-NAND" technology has successfully broken through the blockade. Doesn't this put Nietzsche on the fire?

He knew very well that Nietzsche must keep a low profile now.

Once targeted, Nietzsche had no room to resist.

In the following time, Mo Ran learned more details, and half an hour later, he returned to Nietzsche with a full harvest.

On the other hand, after Li Zhi sent Mo Ran away, he also began to formulate the next mass production plan.

The yield rate optimization of 32-layer flash memory particles continues, but at the same time, small-scale mass production of 32-layer "3D-nand" flash memory particles begins.

And it is first available on the "Jinghong Series" memory cards and Nietzsche mobile phones.

At this time, the role of "Yellow River Storage" in purchasing seven or eight photolithography machines was revealed.

The mass production of 32-layer flash memory particles has been separately arranged with two photolithography machines. Even though mass production has just begun and the production capacity is still in the climbing stage, 32-layer "3D-NAND" flash memory particles are still being produced continuously to ensure " Raw material supply for Jinghong series memory cards.

Soon, Li Zhi discovered that what restricted the production capacity of "Jinghong series" memory cards was not the flash memory particles, but the equipment for producing TF memory cards!

As a last resort, faced with the surging sales of "Jinghong Series" memory cards, Li Zhi quickly purchased another set of "TF memory card" equipment with an annual production capacity of 5 million units.

at the same time.

The "TF memory card" production department also began to operate at an unprecedented intensity, working in two shifts 24 hours a day, and the production capacity of the entire production workshop instantly increased to 200%!

Unlike other manufacturers who work overtime, there was a burst of laughter and enthusiasm in the "TF memory card" production workshop!

"Brothers, here comes the big job, the big money!"
