Chapter 297 CIM storage and calculation integrated chip

The next day, the warm winter sun was shining brightly in Suzhou.

In the office of the general manager of Ruoshui Semiconductor, Jiang Hua was chatting and laughing with Han Leng.

"Old Han, we are all in the dark. The copper wire process in the bonding process is nothing more than a small trick!" Jiang Hua said, taking a sip of Pu'er tea.

Han Leng was stunned for a moment when he heard this. He knew Jiang Hua very well. He had a poor junior high school diploma. When he got into Ming Yueguang, he relied on an undergraduate diploma bought from under the overpass. A person who had never worked in technology was actually very familiar with technology. Jiang Hua has a lot of talk about difficult problems.

"Brother, stop bragging!"

"Brother, why am I bragging? The copper wire process is really not difficult. I found out that the new Kulicke and Soffa bonding machine supports the copper wire process. After purchasing their equipment, the manufacturer's technical support engineers will come to the site to debug the process. Make sure you can produce copper wire technology chips." Jiang Hua shook his lush hair and said.

"really?"

"Of course!" Seeing Han Leng's confused look, Jiang Hua couldn't help laughing.

"Jiang Hua, do you remember Kulicke and Soffa? We used their equipment during the bright moonlight. This equipment is really easy to use." Han Leng felt as if he was illuminated by a beam of light.

"Yes!"

"How did you know that their equipment can do copper wire processing?"

"Last night, I personally cooked and invited Logi to my house to eat Journey to the West chicken and steel tube duck. He told me this personally."

"Wonderful! Wonderful! Wonderful!" After saying that, Han Leng gave a thumbs up.

"I originally wanted to ask Logitech to be our part-time technical consultant, but after hearing what he said, we won't spend that wasted money!"

"Brother Xian, this time it was your Journey to the West Chicken and Steel Pipe Duck that made the big difference!" After saying that, Han Leng patted Jiang Hua on the shoulder.

"Winter is coming, can spring be far behind?" After Jiang Hua finished speaking, he walked to the glass window.

At this time, the winter sun shines in through the glass window and shines on Jiang Hua. He looks like a man made of pure gold.

Compared with the warm winters in Shanghai, the winters in the northern capital are cold.

Early in the morning, Xin Tong and He Weijia rode their bicycles to class together. In the teaching building, they were very surprised to see the poster of Professor Lu Wei's academic lecture. The topic of the lecture was "Storage and Computation Integrated Chip Technology" and its development trends”.

"Xin Tong, if you want to study memory chips in the future, you must attend Professor Lu's lectures." He Weijia said while walking in the teaching building.

"Ok!"

"At seven o'clock in the evening, remember to go to the Science Museum."

Xin Tong nodded.

That night, many people went to the Science Museum to listen to the lecture.

"Before I start the lecture, I would like to ask everyone here, do you know what storage and calculation are?" Professor Lu Wei looked around the entire venue.

"Computing in Memory!"

"CIM!"

……

The response was very enthusiastic! "It seems that everyone is of the same mind, and there are still many people who are silently paying attention to the research of integrated storage and computing memory. Storage and computing integration is to embed computing power in the memory and use a new computing architecture to perform two-dimensional and three-dimensional matrix multiplication and addition operations. ." Professor Lu nodded.

He felt very proud to have found an academic close friend at his alma mater, Tsinghua University.

After speaking, Professor Lu opened his PPT and began the academic sharing in the evening.

Projected on the screen was a man with sharp eyes and a slightly bald forehead.

"Students, the man you see on the screen is a Jew. He has a very high status in the world. He is known as the father of modern computers and is also recognized as the father of game theory in the world!" Professor Lu said about the Jewish people. At this time, the voice was deliberately raised an octave.

"It turns out to be a Jew!"

“The Jewish nation has produced many talented people!”

……

There was a burst of exclamation from the crowd.

"His name is von Neumann. The von Neumann architecture proposed by him laid the foundation for modern computers. It separates the memory and the arithmetic unit. The storage and calculation of data are separated from each other. That is, the data is stored in the memory and requires Then transfer it to the arithmetic machine during calculation. This trick of Lao Feng successfully solved the problem of too small storage capacity and too slow computing speed of computers at that time." Professor Lu said.

When Xin Tong flew to the United States in July, he heard Professor Lu talk about the von Neumann architecture. This time he was able to review the past and learn something new.

It seems that only by breaking the storage wall can we truly liberate computing power!
"With the development of the times, people have discovered the bottleneck of the von Neumann architecture. When matrix operations need to be performed on a large amount of data, the core is multiplication and addition. In this case, the computing power is relatively tight, and we face a huge challenge. Challenge. In 1969, Kautz and others from the Stanford Research Institute proposed the concept of an integrated storage and computing computer. The advantage of integrating storage and computing is to break the storage wall, eliminate unnecessary data movement delays and power consumption, and use storage units to increase computing power. , improve computing efficiency hundreds or thousands of times, and reduce costs, but the ideal is very full, the reality is very skinny, this path has not yet been explored." After speaking, Professor Lu shook his head.

After a pause, he raised his voice an octave: "Those who can solve this problem must be our Tsinghua students!"

The crowd immediately burst into warm applause.

“Recently, scientists have been studying reducing the path between memory and processing units, such as 3D stacking through 3D packaging technology. New memories formed by stacking multiple layers of DRAM can provide greater memory capacity and memory bandwidth. However, these The bold attempt has not changed the problem of separation of data storage and data processing, and cannot fundamentally solve the bottleneck of von Neumann computing architecture." After speaking, Professor Lu shook his head again.

After a pause, he raised his voice an octave again: "Overthrowing the storage wall can greatly increase computing power and will promote the rapid development of human science and technology. Whoever solves this technology will definitely win the Nobel Prize." , if I solve this problem, I will definitely find investors to open a listed company, and then I will definitely become a world-class super rich man!" After Professor Lu finished speaking, a proud smile appeared on his face.

He has been studying this topic recently and has seen a glimmer of light ahead.

The crowd immediately burst into laughter. I never expected that the end of science would be a listed company.

"Come on, Professor Lu!"

"You can definitely do it!"

……

Seeing the smile on Professor Lu's face, everyone applauded and cheered for him.

Xin Tong also clapped along with everyone.

He Weijia stood up in excitement, applauded and gave a thumbs up.

"Professor Shaotang Cai of the University of California, Berkeley, published the paper "Memristor: The Missing Circuit Component" in 1971. He provided the original theoretical structure of memristor and speculated that the circuit has a natural memory ability, even if the power is interrupted. To achieve the integration of storage and shorten the distance between storage and computing, that is, to break the storage wall, I think that to develop a new integrated storage and computing chip, memristor as a storage medium is a good choice." At the end of the technology sharing, Professor Lu Wei gave his own technical judgment and research direction.
