I Got Divorced and Found a Thousand Bitcoins Episode 074
I could tell the moment I saw him.
‘An incredible golden light…’
The golden light emanating from his body was shining more brilliantly than any light I had ever seen.
It was as if all the luck in this world had gathered and been visualized into this form.
‘This isn’t the time for this.’
Since I couldn’t ignore Chairman Lee Jae-seong’s outstretched hand indefinitely, Kang Hyeon came to his senses and shook hands with him.
“I’m Choi Kang-hyeon from KH Capital. And this is Nathan, former CEO of Nereid and currently head of the research division.”
“Pl… Pleased to meet you! I’ve been wanting to meet you!”
Nathan’s voice was already getting excited.
His tension was so high that you could feel his excitement, and when I was getting worried, Ha-ryul beside him grabbed Nathan’s collar and pulled.
Tug!
At her restraint, Nathan quickly came to his senses and cleared his throat.
Seeing this, Kang Hyeon was once again convinced that bringing Ha-ryul was the right answer.
‘As expected, Nathan is someone you never know which way he’ll go.’
If he hadn’t brought Ha-ryul, his rampage wouldn’t have stopped.
Taking a breath of relief, Kang Hyeon greeted Chairman Lee Jae-seong again.
“Thank you for making time today.”
“Haha, not at all. I was the one who made the request first. Thank you for coming so readily. Shall we sit down and talk?”
“Yes.”
Lee Jae-seong had a more down-to-earth image than expected.
There were rumors that his TV appearances were acting, but the man I actually met had the same image.
The two sides sat facing each other at a long table, with Lee Jae-seong and Kang Hyeon as representatives exchanging conversation.
“I was really surprised when I heard the news. Our group’s researchers thought the liquid immersion cooling system would only be possible in 1-2 years.”
“Actually, we expected the same.”
“You too, CEO Choi?”
“Yes. Thanks to Nathan’s genius brain that exceeded my expectations, the system was completed quickly.”
“Oh…”
Lee Jae-seong’s gaze turned to Nathan.
His eyes were sparkling so brightly it was burdensome, but to think he was that level of genius.
‘He’s making me see him differently.’
Revising his evaluation of Nathan, Lee Jae-seong looked back at Kang Hyeon and brought up the topic.
“The reason I contacted you, as you probably expected, is because I’m curious whether the liquid immersion cooling system can be applied to our Saseng Electronics’ HBM.”
It was as expected.
Saseng Electronics, which could be called the core of Saseng Group, had grown into a global company through smartphones and currently held the world’s number one position in DRAM.
DRAM was central to the AI industry and required enormous quantities, so Saseng Electronics built a semiconductor factory in Pyeongtaek spending trillions of won to meet that demand.
In the early stages of factory construction, there were voices saying Chairman Lee Jae-seong was overreaching, but currently the dominant assessment was that it showed his foresight.
“As you know, HBM4 has been developed and commercialized.”
“Huh? Wasn’t that commercialized by LK Nix, not Saseng Electronics?”
“Nathan!”
Nathan’s comment was rude.
If handled wrong, it could even touch Chairman Lee Jae-seong’s nerves.
Indeed, the faces of what appeared to be his accompanying secretaries visibly hardened.
But Lee Jae-seong actually laughed heartily and acknowledged it.
“Haha, that’s right. Our Saseng Electronics is still struggling with development.”
“I’m sorry. Nathan was rude…”
“Not at all. Don’t people called geniuses tend to be full of personality? I understand. Above all, it’s also the truth.”
Bitterness showed in Chairman Lee Jae-seong’s eyes.
“Actually, we at Saseng Electronics can also make HBM4 12-stack, the same as LK Nix.”
“Chairman, that story…”
“Ah, it’s fine. This much is something everyone knows anyway.”
The most important thing in HBM4 was the number of stacks.
12-stack meant 12 DRAMs stacked vertically, boasting high capacity.
In HBM4, how many you could stack vertically was the technology and competitiveness in the market.
“The HBM4 that LK Nix is currently supplying to Nvidia is 12-stack. For us to have competitiveness, we need to release higher 16-stack or develop HBM5.”
“But with current technology, isn’t it difficult to make that many stacks?”
Lee Jae-seong nodded at Nathan’s question.
“That’s right. There are technical limitations. Above all, the obstacle is…”
“Heat generation, right? Higher stacks means stacking that many more DRAMs very precisely. When that happens, enormous heat is generated when processing data. If you can’t control that, it’ll be judged as defective.”
“Exactly.”
When stacking DRAMs, each stack’s height was at most 10 micrometers or less.
Converting this to centimeters, it could be said to be 1/10,000th of a centimeter.
When DRAMs stacked this densely process data, naturally enormous heat is generated.
In the modern HBM market, how to control this heat generation was actually the most important issue.
“What I’m curious about is whether the liquid immersion cooling system can be applied to HBM as well. And if it can control heat generation, to what extent can it control it.”
At Lee Jae-seong’s words, Nathan fell into thought for a moment.
Seeing him suddenly become silent, Kang Hyeon was flustered.
‘Is this a difficult question to answer immediately?’
The liquid immersion cooling system was new technology that Nathan had led in creating.
Therefore, he was the one who had to answer Chairman Lee Jae-seong’s question, but seeing him unable to answer immediately was flustering.
Then Nathan, who had been pondering for a while, opened his mouth.
“Have you succeeded in developing HBM5 technology internally?”
CEO Lee Jae-seong’s face hardened.

United States.
At Whiterock Credit headquarters, Rosenthal sat in his office anxiously waiting for something.
‘Damn… when is the contact coming?’
Having received his last chance from Chairman Base, he had left a message asking Nvidia Chairman Robert Hwang to contact him.
But even after 3 days, no reply had come yet.
‘That bastard Robert… in the past he would wait 5 minutes to borrow money from us…!’
Current Nvidia had become a giant corporation ranked first in NASDAQ market cap, but it wasn’t always that way.
When they were selling graphics cards, their business became difficult and they went through precarious times when Robert Hwang personally ran around doing sales.
Knowing Robert who had acted as his attendant when trying to borrow money from him back then, Rosenthal didn’t like the current situation.
Then his smartphone rang.
Buzz!
[Robert Hwang]
Confirming the number and name, he answered the phone immediately as if he had never been angry.
“Oh! Robert, it’s been a while.”
-Ah, yeah. Sorry but I’m busy right now. Can we get straight to the point?
At Robert Hwang’s blunt voice, Rosenthal frowned, but what was important now wasn’t his pride.
“Ah, sure. Can’t hold a busy person on a long call. It’s nothing else, but I have something important to discuss with you regarding the liquid cooling system that was recently developed.”
-Liquid cooling system?
“Right. It’s a story that could benefit you too. Could you spare me some time?”
-Hmm… Alright. I’m returning to the United States in 4 days…
“No. You’re in Dubai right now, right? I’ll come straight there.”
-…Is it that urgent?
“Of course. Time is money, isn’t it?”
-Alright. Then let’s meet in Dubai.
Rosenthal, who had hung up the phone, clenched his fist.

The suite room at the Shilla Hotel was enveloped in silence.
It was the impact of Nathan’s single remark.
Kang Hyeon was trying to interpret Nathan’s words that had been thrown out without consulting him.
‘HBM5? The HBM that LK Nix is currently supplying to Nvidia was model 4, wasn’t it? Are you saying Saseng has already internally developed a more advanced model than that?’
HBM was currently the core model leading the semiconductor market.
The company running first place in this field was LK Nix, which held the number one global market share.
The model that LK Nix supplied was HBM model 4, 12-layer.
The maximum layers that could be stacked in model 4 was 16 layers, and LK Nix had completed development of this as well and had released articles saying they would soon supply it to Nvidia.
With just that, LK Nix’s stock price broke through record highs and KOSPI surpassed 4,000 points.
‘But a more advanced HBM5 model than that. What would happen if this news became known to the world?’
Without a doubt, Saseng Electronics would break through record highs and KOSPI would certainly exceed 5,000 points.
One puzzling thing was why Saseng wasn’t making this public.
Then Nathan continued speaking on behalf of Lee Jae-seong, who remained silent.
“Air cooling is sufficient for HBM model 4. LK Nix also managed the heat generation of model 4, 16-layer with air cooling.”
LK Nix’s announced model 4, 16-layer was at a level where commercialization was currently possible.
In other words, it meant they had technology that perfectly controlled heat generation.
‘Ah…!’
Hearing this far, Kang Hyeon could vaguely understand the problems with Saseng Electronics’ developed HBM5.
Nathan supplemented that vague information he knew.
“They developed HBM model 5, but the problem is they couldn’t control the heat generation. So while they couldn’t make it public, they contacted us who developed immersion cooling.”
Nathan’s deduction was perfect.
The question was whether the conclusion reached at the end of that deduction was correct.
Then Lee Jae-seong, who had been keeping silent, let out a sigh.
“Phew… You’re sharp. To grasp our company’s confidential information at once just from the fact that immersion cooling is needed.”
What those words meant was one thing.
“Did Saseng really develop HBM model 5?”
“Yes, that’s correct. We developed model 5 and even finished testing. The performance is naturally better than the existing model 4.”
“My estimate is that it would perform more than twice as well as model 4?”
At Nathan’s words, Lee Jae-seong showed a surprised expression again.
“Haha, to think you’d figure out even that far. That’s right. In terms of simple performance alone, there’s a 2x difference. The actual performance would be even better than that.”
“The problem would be heat generation. With model 5, existing air cooling would absolutely be unable to control the heat.”
“Yes. That’s why we can’t make it public. In the PVT test stage, we can’t control the heat generation and errors occur.”
Now everything was understood.
The reason Saseng Electronics wanted to apply their immersion cooling technology.
The new technology they developed had problems that couldn’t be solved with existing air cooling.
‘This means that to mass-produce HBM model 5 in the future, our immersion cooling system would become the standard, right?’
Immersion cooling was currently technology that Nereid exclusively possessed worldwide.
Over time, other companies would also have related technology, but the important thing was that they could make exclusive contracts with the two companies developing HBM.
‘This makes more money than I expected.’
The golden light that Lee Jae-seong had been emitting.
That didn’t mean the wealth or luck he possessed.
What it meant was showing how much help it would be to Kang Hyeon himself.
