Rebirth: I carry a desktop computer inside me

Maple Fire Group Corporation, Resistance Memory R&D Center.

After more than half a year of continuous research and development, Feng Gaoping, who is already a Mediterranean hairstyle, led the team, under the guidance of Jiang Cheng, to thoroughly eat the patents of Xu Dawei and their team, and on this basis, he developed and realized mass production technology.

"Mr. Jiang, at present, we have initially realized the research and development of two memory chips, the first type is the resistance cache, which we call HRRAM, the read speed has reached 35GB/S, which can be used for mobile phone SOC chips, automotive-grade chips."

Feng Gaoping took a small chip smaller than the nail of his little finger and handed it to Jiang Cheng to see.

"THE SECOND TYPE IS RESISTIVE MEMORY, DRRAM, WHICH IS MANUFACTURED BY 90NM, BUT THE STORAGE CAPACITY IS 4GB AND THE READ SPEED IS 20GB/S."

Jiang Cheng took it in his hand and instantly simulated entering the ultra-technical laboratory in his body.

"What about write speed?"

"The sequential write speed is also 10GB/s, and the random write is also more than 2GB/s." Feng Gaoping's voice was very excited.

This is the first time he has developed such a powerful memory chip.

Compared to the current phone memory, reading is 10 times faster and writing is 20 times faster!

Jiang Chengjing replaced these chips with the Maple Fire mobile phone in the in vivo simulation laboratory, and first changed the running memory.

The relevant interface protocols are synchronously copied to the chip-scale system.

"Sequential read and write speeds are very good." Jiang Cheng nodded, "However, you have to add another power management chip to prevent the memory chip from being broken down due to unstable current and voltage."

Feng Gaoping responded, admiring Jiang Cheng very much, "We also found that this problem may occur in the test, and we are already making suitable power management chips." "

Well done." Jiang Cheng praised, and then asked, "You graduated from the National University of Science and Technology, right?"

"Yes, microelectronics science." Feng Gaoping replied, "It's been four or five years since I graduated.

"After today, you will be the manager of the memory R&D department, and you will do a good job." Jiang Cheng patted him on the shoulder.

During this period of investigation, Feng Gaoping's performance is indeed remarkable.

At least look at him like that, it doesn't look like he just graduated four or five years, at least more than ten years after graduation.

Feng Gaoping was a little excited, "Thank you President Jiang for trust!"

"Continue to develop and improve, the current process I am still not very satisfied, hope to reach 45 nanometers, even 28 nanometer process, in addition to such a large chip, to explore the 3D stacking structure, the capacity to expand to 10GB, or even more than 100GB."

"Understand, let's go in the direction that President Jiang pointed to. This memory chip, if it were not for the complete set of patents published by you, we would not have achieved results.

Jiang Cheng nodded, "Okay, don't say flattery." After designing the power management supporting chip, I will let the Maple mobile phone department come to dock in order to design the hardware and adapt the system well. In

his eyes, with this resistive memory chip, not only can the card background be better realized in the system, but also will realize the shutdown and boot up, just like the screen is as fast as turning off the screen!

Just this time to let the two parties dock, when Fenghuo's EX2 mobile phone is released, this invincible killer can come in handy.

Feng Gaoping then tentatively said, "Then is our resistance buffer docked with the SOC chip R&D department of the semiconductor company?"

Jiang Cheng didn't answer him, just asked, "By the way, have the costs of these two chips been calculated?"

"It depends on the production situation, the resistance cache is 64MB, and the cost is expected to be about 100 yuan; 4GB for memory costs around 150 yuan. Feng Gaoping roughly calculated, "Of course, the subsequent improvement of the process, the cost will be diluted." "

Jiang Cheng gently calculated the meeting in his mind, feeling that the commercial problem was not big, and the profit could be guaranteed." As soon as possible, let our own mobile phone application on, from the second half of next year, can be supplied to various mobile phone manufacturers. "

Of course, the price needs to be higher.

Feng Gaoping patted his chest, "President Jiang, don't worry, within a month, we will dock with the personnel of the mobile phone department and strive to start OEM stocking in March."

"Well, then look at the situation, and I'll decide how much to stock." Jiang Cheng reminded.

"Okay."

Leaving the R&D department, Jiang Cheng's mood improved.

This new type of memory chip is finally on the curve, surpassing the cars of Sanxing, Hynix and Micron.

Otherwise, most of this type of memory chips rely on them.

Hey! Maybe in a year or two, the so-called Big Three will also have to add a chair!

----ヽ(✿゚▽゚)ノ----

After Jiang Cheng simulated the entire new resistive memory chip into the vivo ultra-technology laboratory, he only did a lot of simulation experiments on read and write performance.

In the specific adaptation application, it has not been tried.

Back in the office, Jiang Cheng leaned back in his chair, closed his eyes, and began to carefully explore and develop in the internal computer.

Consciousness entered the simulated mobile phone assembly and test laboratory.

Huge mobile phone production line and test experiment area, all kinds of instruments and equipment.

Previously, Jiang Cheng had replaced the running memory of the mobile phone with the resistive memory chip, turned on the machine, began detailed testing, and fine-tuned the system program.

This block is mainly adjusted in the system kernel for memory scheduling in this area.

Jiang Cheng has studied this aspect when he was developing compilers and mobile phone FIUI systems, and his level is definitely no worse than this group of R&D personnel.

Although it is more difficult to modify it by himself, in the internal computer, Jiang Cheng's speed is extremely fast, and it took some time to adjust the key parts first.

For example, in this running memory, allocate 512M of memory as a dedicated background card storage area.

At that time, after the mobile phone runs the APP program, if it is switched, the system will seal the main data at the moment of exiting the program, no matter how many programs are switched, it can still be saved there.

If it is called again, the system will call up the card background out, and due to the characteristics of resistance storage, the card information will not be lost and can be applied immediately.

After Jiang Cheng's initial adjustment, an hour has passed, and it has been tested several times in the in vivo laboratory, whether it is Weixin or games, or opening ten other applications, switching at that time is very silky.

It's just incredible.

Only some pity is that the current process is a little old, if it is a 28nm process, then the capacity will quickly reach 10GB or even tens of GB of running memory.

At that time, users really don't have to worry about any memory killing problems.

There was a knock on the door.

Jiang Cheng opened his eyes, "Come in."

Lou Xiangwan opened the door and reported to him, "President Jiang, Vice President Chen Feng has something to report to you. "

Come in." Jiang Cheng temporarily collected his thoughts, allowing the laboratory in his body to continue to be distracted to test the situation of the cache.

Chen Feng came in formally dressed and took a blue folder.

"Mr. Jiang, the equity incentive plan, I have preliminarily formulated one, and I want to report to you." Chen Feng handed the folder over.

After Jiang Cheng answered, he nodded, "The headquarters is about to be moved, and it is just right to have this news released." After the relocation, we officially implemented it. "
