The selection of Micron Technology's UMCP5 model flash memory product as a comparison product for Longzang generation memory chips was made after negotiation.
First of all, Micron’s ‘UMCP5 model flash memory product’ is very representative and is the world’s first multi-chip packaging 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.
Neither in terms of performance nor status.
Moreover, Micron Technology is also one of the most important semiconductor manufacturers in the United States, occupying a huge market share.
If carbon-based chips want to seize share from the silicon-based chip market, they must break through the blockade of Western interest groups.
It is very important to choose a 'suitable' target as a 'friendly businessman'.
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, networking and mobile portable products.
More importantly, Micron Technology is extremely unfriendly to them.
It is no exaggeration to say that among those Western interest groups, Micron is a knife in their hands, and Micron itself takes the initiative to send it, acting as a vanguard every time.

With the busy work of the staff, the storage tester for the experiment was quickly installed.
A Micron Technology ‘UMCP5 model flash memory product’ and a first-generation ‘Longzang memory chip’ were placed into the test port respectively.
Under the debugging of on-site staff, the test began quickly.
Through a dedicated connection device, the storage tester put the test data of the two memory chips on the projector, and everything was quickly presented in front of everyone without reservation.
Through the picture on the large screen, you can clearly see the various indicators displayed during the test.
For a storage product, 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 large screen, and the overall fluctuation is between 5900Mbps-6200Mbps.
Although it is slightly lower than the 6400Mbps data transmission rate stated by Micron Technology at the product launch, for a mature flash memory product, this transmission speed is already very powerful.
However, what shocked everyone was that the transmission rate reported by the Longzang generation memory chip test was as high as 25759Mbps.
This speed is 4.2 times that of Micron Technology’s UMCP5 model flash memory product! It reaches an astonishing 25.76Gbps!
In front of the transfer rate of the Longzang generation memory chip, let alone the UMCP5 model flash memory product launched by Micron Technology in 2020, even the flash memory product with the fastest transfer rate on the market today is completely incomparable.
Currently, the flash memory product with the fastest transfer rate on the market is the LPDDR5T memory launched by SK Hynix, the world's second largest memory chip giant.
The data transfer rate of LPDDR5T can reach 9.6Gbps, which is 13% higher than the 8.5Gbps of LPDDR5X. It is the fastest memory so far.
However, there is still a gap of three times between the 9.6Gbps data transfer rate and the 25.76Gbps data transfer rate of the Longzang generation memory chip.
When this key indicator was presented to everyone, the scene was in an uproar.
With a data transfer rate of up to 25.76Gbps, there is no doubt that it directly kills all silicon-based chip storage products, leaving all attendees at the scene dumbfounded in surprise.
Not to mention Micron Technology's UMCP5, the LPDDR5T memory launched by SK Hynix, and the DDR6 memory launched by Samsung are completely inferior to them.
Not only that, in terms of random read latency parameters, the performance of Longzang generation memory chips also far exceeds that of UMCP5 model flash memory products.
Random access is the most well-known function in memory. Of course, it also has its own special classification.
It’s just that the two products tested today have integrated related functions.
As long as you know the address of memory row
Judging from the on-site test experimental data, the random read delay of the UMCP5 flash memory product is about 7 milliseconds, while the random read delay of the Longzang generation memory chip is only about 4 millimeters.
This means that if mobile phones, PC computers, servers and other products use Longzang generation memory chips, they will have stronger software response speed, boot speed, etc.
Because the most direct manifestation of random read latency in performance is the speed of switching on and off, the speed of software opening, etc.
Transfer rate, random read latency, write recovery time, memory refresh time, error detection vectors, memory cell short circuit...
Tests were completed one after another, and various test data were displayed in front of everyone through the large screen on site.
Although in some aspects, the performance of Longzang generation memory chips may only be the same as, or slightly inferior to, UMCP5 model flash memory products.
But in general, whether it is the most critical transmission rate, random read delay, write recovery time and other core indicators of memory chips, the Longzang generation memory chip has killed the former.
Witnessing the field test data of the Longzang generation memory chips, everyone present, whether they are manufacturers in the silicon-based semiconductor field, scholars in the semiconductor field, or government executives, have no idea about the carbon-based carbon-based semiconductors being released today.
Chip, there is no longer any suspense.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! Even though some people thought that Xinghai Research Institute may have just released a concept about carbon-based chips, and there are no real carbon-based chips that can be used commercially.
Not made.
At this moment, there is no longer any controversy.
They not only talked about it and disclosed the conceptual data to everyone, but also directly put in front of everyone a product that can be used and whose performance far exceeds that of silicon-based semiconductor chips.
Although this is just a memory chip and not a mobile phone's CPU or GPU, 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 Micron Technology CEO Sanjay Mehrotra has now turned into deep fear and panic.
Even if he still has ten thousand disbeliefs in his heart, and no matter how much he thinks that Xinghai Research Institute will never be able to develop a commercialized carbon-based chip, at this moment, he must admit the small desire in his heart.
It has completely broken.
Everything he longed for and placed his trust in was completely shattered by the tiny chip on the stage at this moment.
Even if he doesn't want to accept this fact, when the ironclad fact is placed in front of him, everything is of no avail.
At the same time, Intel CEO Pat Gelsinger, who was sitting on the other side, also had shock written all over his face.
The performance of the Longzang generation memory chips is really shocking.
Although this is just a small pure chip, the transmission rate that is four or five times that of silicon-based chips is enough to reflect everything.
After all, carbon-based chips have shown such exaggerated performance on memory chips. What if it is applied to other chip fields such as CPU/GPU?
A trace of imperceptible fear was reflected from the depths of his pupils.
Of course, compared to Sanjay Mehrotra, CEO of Micron Technology, the look on Pat Gelsinger's face is much better.
After all, the product being compared on stage right now is not his product, right?
What can be seen is that after today's product launch, when the news of the Longzang generation memory chips is revealed, the silicon-based memory chip field will suffer a huge blow.
Not to mention Micron Technology, the entire field of silicon-based semiconductor memory chips will suffer a fatal blow.
Whether it is Samsung, SK Hynix, Toshiba, Western Digital and other leading companies in the world's memory chip field, they will be abandoned by the market.
Micron Technology, the product that was brought on stage for comparison, was the first company to bear the brunt of the impact.
...
The on-site demonstration of Dragon generation memory chips has been completed, and the product launch conference on carbon-based chips is coming to an end.
However, to everyone's surprise, after the carbon-based chip was introduced, the product launch conference did not officially end, but a new host was replaced.
Important partners in the research and development of carbon-based chips, from Huawei HiSilicon to SMIC, all stood up and showed their faces.
This can also be regarded as a friendly gesture to carbon-based chip R&D partners. After all, being able to show your face at the product launch of carbon-based chips can definitely greatly enhance the company's visibility, stimulate the development of the company, and increase the visibility of the product.
wait.
Unsurprisingly, what Warwick has unveiled is its new generation product ‘Dragon’ series.
This is a brand new series of products, including smartphones, PCs, telecommunications routers, whole-house intelligence and other products and equipment, which will all use the Xiongxin series carbon-based chips as the core.
Moreover, representatives of Warwick stood on the stage and made bold statements, announcing that within five years, all mobile phone products would be replaced with carbon-based chips, and they would cooperate with Xinghai Research Institute to achieve a comprehensive upgrade of domestic chip technology!
Representatives from SMIC took to the stage to demonstrate carbon-based chip test products and preparation technologies of three different grades: 28 nanometer, 23 nanometer and 20 nanometer.
And they will build two carbon-based chip processing plants in selected provinces in mainland China.
More importantly, at the product launch conference, representatives from SMIC publicly demonstrated the ‘laminated weaving engraving technology’ that is unique to carbon-based chips!
At present, the engraving precision of this chip processing and preparation technology has reached the micron level, and a finished carbon-based chip with 500,000 transistors has been produced.
And more importantly, this technology does not require the use of a photolithography machine.
This means that it can completely bypass the core bottleneck equipment in the semiconductor chip field of Western interest groups!
Not surprisingly, when this technology was announced, the entire scene immediately became excited.
