The choice of Micron Technology's UMCP5 flash memory product as a comparison product for Longzang's first generation storage chip was discussed.

First of all, Micron's 'UMCP5 flash memory product' is very representative and is the world's first multi-chip package product based on LPDDR5 DRAM.

Although it is a product of 2020, even now, there are still a large number of customers using or purchasing it.

Whether in terms of performance or status, there is nothing to say.

Moreover, Micron Technology is one of the most important semiconductor manufacturers in the United States, occupying a huge market share.

If carbon-based chips want to seize market share from silicon-based chips, they must break through the blockade of Western interest groups.

And choosing a 'suitable' target as a 'friendly competitor' is very important.

Micron Technology is very good. It is one of the world's leading suppliers of advanced semiconductor solutions. Its products are widely used in cutting-edge computing, consumer products, networks and mobile portable products.

More importantly, Micron Technology is extremely unfriendly to them.

It is no exaggeration to say that Micron is a knife in the hands of those Western interest groups, and it is Micron who took the initiative to offer it, and every time it acts as a pioneer.

With the busy work of the staff, the storage tester for the experiment was soon installed.

A Micron Technology's 'UMCP5 model flash memory product' and a first-generation 'Longzang storage chip' were placed in the test port respectively.

Under the debugging of the on-site staff, the test started soon.

Through the dedicated connection equipment, the storage tester projected the test data of the two storage chips onto the projector, and everything was presented to everyone without reservation and quickly.

Through the picture on the big screen, you can clearly see the various indicators displayed during the test.

For a storage product, the data transfer rate is undoubtedly one of the most important indicators.

The data transfer rate of the 'UMCP5 model flash memory product' can be clearly seen from the big screen, and the overall fluctuation is between 5900Mbps-6200Mbps.

Although it is slightly lower than the 6400Mbps data transfer rate stated by Micron Technology at the product launch conference, this transmission speed is already very impressive for a mature flash memory product.

However, what shocked everyone was that the transmission rate reported by the test of the first generation of Longzang memory chips was as high as 25759Mbps.

This speed is 4.2 times that of Micron Technology's UMCP5 model flash memory products! It reached an astonishing 25.76Gbps!

In front of the transmission rate of the first generation of Longzang memory chips, let alone the UMCP5 model flash memory products launched by Micron Technology in 2020, even the flash memory products with the fastest transmission speed on the market are completely incomparable.

At present, the flash memory product with the fastest transmission speed on the market is the LPDDR5T memory launched by SK Hynix, the world's second largest memory chip giant.

The data transmission rate of LPDDR5T can reach 9.6Gbps, which is 13% higher than the 8.5Gbps of LPDDR5X, making it the fastest memory to date.

But the data transfer rate of 9.6Gbps is still three times higher than the 25.76Gbps data transfer rate of the first generation of Longzang memory chips.

When this key indicator was presented to everyone, there was an uproar at the scene.

With a data transfer rate of up to 25.76Gbps, there is no doubt that it directly killed all silicon-based chip storage products, which surprised the participants.

Not to mention Micron Technology's UMCP5, even the LPDDR5T memory launched by SK Hynix and the DDR6 memory launched by Samsung are not enough in front of it.

Not only that, in terms of random read latency parameters, the performance of the first generation of Longzang memory chips also far exceeds that of UMCP5 model flash products.

Random access is the most well-known function of memory, of course, it also has a special classification.

It's just that the two products tested today have integrated related functions.

As long as the address of the memory row X and memory column Y where the unit is located is known, the function of any storage unit can be directly accessed. It is very important whether it is on the storage chip or on the CPU/GPU chip.

According to the test data on site, the random read delay of the UMCP5 model flash memory product is about 7 milliseconds, while the random read delay of the Longzang first generation storage chip is only about 4 milliseconds.

This means that if mobile phones, PCs, servers and other products use Longzang first generation storage chips, they will have stronger software response speed, boot speed, etc.

Because the most direct manifestation of random read delay in performance is the speed of switching on and off and the speed of software opening, etc.

Transmission rate, random read delay, write recovery time, memory refresh time, error detection vector, storage unit short circuit.

One test after another is completed, and various test data are displayed to everyone through the large screen on site.

Although in some aspects, the performance of Longzang first generation storage chips may only be on par with UMCP5 model flash memory products, or even slightly inferior.

But in general, whether in the most critical transmission rate, random read latency, write recovery time and other core indicators of memory chips, Longzang's first generation memory chips have blown away the former.

After witnessing the on-site test data of Longzang's first generation memory chips, all the people present, whether they are manufacturers in the field of silicon-based semiconductors, scholars in the field of semiconductors, or executives of government departments, no longer have any suspense about the carbon-based chips released today.

Even though some people previously believed that Xinghai Research Institute may have only released a concept of carbon-based chips, and the real carbon-based chips that can be used commercially have not been made.

At this moment, there is no controversy.

They not only talk about it, but also disclose the conceptual data to everyone. They even directly put the products that can be used and have performance far exceeding that of silicon-based semiconductor chips in front of everyone.

Although this is just a memory chip, not a CPU or GPU for a mobile phone, when the complete memory chip is displayed, are other functional chips still far away?

Sitting in the front row, the embarrassment and dissatisfaction on the face of Sanjay Mehrotra, CEO of Micron Technology, has now turned into deep fear and panic.

Even if he still has ten thousand unbeliefs in his heart, even if he thinks that Xinghai Research Institute will never be able to develop a commercial carbon-based chip, at this moment, he must admit that the tiny desire in his heart has been completely broken.

What he longed for and pinned on has been completely shattered by the small chip on the stage at this moment.

Even if he is unwilling to accept such a fact, when the iron-clad facts are placed in front of him, everything is useless.

At the same time, Intel President Pat Gelsinger, who was sitting on the other side, was also full of shock on his face.

The performance of Longzang's first generation of memory chips is really too shocking.

Although this is just a small pure chip, the transmission rate of up to four or five times that of silicon-based chips is enough to reflect everything.

After all, carbon-based chips have shown such exaggerated performance in memory chips. What if they are applied to other chip fields such as CPU/GPU?

A subtle fear was reflected from the depths of his pupils.

Of course, compared to Sanjay Mehrotra, the CEO of Micron Technology, Pat Gelsinger's expression was much better.

After all, it was his product that was being compared on the stage at the moment, wasn't it?

It was obvious that after today's product launch, when the news of Longzang's first-generation memory chip was revealed, the silicon-based memory chip field would suffer a huge blow.

Not to mention Micron Technology, the entire silicon-based semiconductor memory chip field would suffer a fatal blow.

Whether it was Samsung, SK Hynix, or Toshiba, Western Digital and other leading companies in the world's memory chip field, they would be abandoned by the market.

And Micron Technology, which was pulled onto the stage for comparison, was the first to suffer the most severe impact.

The on-site display of Longteng's first-generation memory chip was over, and the product launch conference on carbon-based chips was also coming to an end.

However, to everyone's surprise, after the introduction of the carbon-based chip, the product launch conference did not officially end, but a new host was replaced.

From Huawei HiSilicon to SMIC and other important partners in the development of carbon-based chips, they all stood up and showed their faces.

This can be regarded as a friendly expression to the carbon-based chip R\u0026D partners. After all, being able to show your face at the carbon-based chip product launch conference can definitely greatly enhance the company's reputation, stimulate the development of the enterprise, and open up the popularity of the product, etc.

And unsurprisingly, Huawei publicly disclosed a new generation of products, the 'Dragon' series.

This is a brand-new series of products, including smart phones, PCs, telecom routers, whole-house intelligence and other products and equipment, which will fully adopt the Xiongxin series carbon-based chips as the core.

In addition, Huawei's representatives also stood on the stage and made lofty ambitions, announcing that within five years, mobile phone products will be fully replaced with carbon-based chips, and cooperate with Xinghai Research Institute to achieve a comprehensive upgrade of domestic chip technology!

And SMIC's representatives came on stage to show the three different grades of carbon-based chip test products and preparation technologies of 28 nanometers, 23 nanometers and 20 nanometers.

And they will build two carbon-based chip processing plants in selected provinces in the mainland.

More importantly, at the product launch conference, representatives of SMIC publicly demonstrated the "layered weaving engraving technology" unique to carbon-based chips!

At present, the engraving accuracy of the chip processing and preparation technology has reached the micron level, and a finished carbon-based chip with 500,000 transistors has been prepared.

And more importantly, this technology does not require the use of a photolithography machine.

This means that it can completely bypass the most core equipment in the semiconductor chip field that is stuck in the neck by Western interest groups!

Not surprisingly, when this technology was announced, the whole scene was boiling.
