      Coming domestic SSD market Samsung showed 3D V-NAND Shang Fang sword



      On the 9th of this month, Samsung announced the development of a 1Tb (terabit) 3D V-NAND chip. It is reported that the capacity of the V-NAND chip (ie vertically stacked 3D V-NAND) developed by this time is double that of the current largest memory of 512Gb (gigabit).


      Samsung Electronics took the lead in implementing V-NAND (Gen 1, 24) production worldwide in 2013 and this year has led to the fourth generation of V-NAND production leading innovation. Recently, Li Junke, chief technology officer of the storage division of Samsung Electronics Research Institute in Xi'an, said in an interview with Feixun that the number of 3D V-NAND stacks in the market has reached a relatively high level now and 3D V-NAND technology has become the mainstream . Samsung's 3D V-NAND technology is the de facto industry benchmark. Now the mainstream product is the third generation of V-NAND. The fourth generation is also coming soon. Samsung's advanced technology also ensures the V-NAND technology can last Innovation.

      "Samsung will continue to promote technological innovations in V-NAND to increase the number of layers, such as the third generation of 48 layers, the fourth generation of 64 layers and the fifth generation of more than 90 layers.Other manufacturers 3D V-NAND is also being followed up, but it is not easy to achieve stable production volume.Samsung has accumulated a lot of experience in the development and production of 3D V-NAND, and is ready to introduce new technologies, in addition to just mention Including the addition of vertical stacking, the Lateral Shrink, and the Cell over Peripheral (COP) technology that builds cell layers onto peripheral-supporting CMOS. "

      Today, the performance of flash-based storage products is rapidly growing, and high-performance SSDs reach or exceed the speed of the transfer bus. The impact on the system architecture of datacenters, which are typically used for big data and cloud computing, has become more important as how to make data more valuable. The value of the data is very similar to the value of the network as defined by Metcalfe's Law, whose value is measured by the capabilities of Size, Speed, and Scale. Li Junke pointed out that SSD can affect the data center architecture through High capacity, low latency and New interface, and Samsung also prepared corresponding solutions for these needs such as 128TB high-capacity SSD, ultra-low latency Z-SSD and new interface Features Key-Value SSD.

      Cloud computing, big data prevalence of the moment, the most can not be ignored is artificial intelligence, Samsung Semiconductor as the global DRAM and NAND industry leader, also very concerned about the development of AI. According to reports, in order to deal with the arrival of artificial intelligence, Samsung launched a special type of DRAM for AI / ML applications, called HBM (High Bandwidth Memory). HBM specifically optimizes access bandwidth for big data calculations at speeds up to 2Gbps. HBM products are now widely used in a variety of applications that require AI / ML (data centers, smart cars, etc.).

      Speaking about the status of Samsung SSD at home and abroad, Li Junke said that in addition to China, Samsung SSD in the server industry has accounted for 70% of the global SSD market share. This means that Samsung SSD has been recognized by global IT companies such as Google, Amazon, IBM, Hewlett-Packard and so on.

      "Samsung SSD has won ODCC Best SSD Award for two consecutive years and we hope we can make more users aware of our good products through ODCC platform. Frankly speaking, Samsung SSD is more stable than other manufacturers Performance, I hope more Chinese companies understand the performance and reliability of our SSD. "

      If you want to gain a firm foothold in the country and gain a bigger share, you will inevitably have to talk about the differences and advantages between Samsung's SSDs and your competitors' SSDs. Li Jun Ke said that the current SSD market continues to be hot, there are constantly veteran manufacturers and emerging manufacturers to launch new products to market. Among the many SSD manufacturers, Samsung SSD is the only vendor with a complete suite of solutions including PCB design and final assembly from NAND flash particles to SSD controllers to SSD firmware and even SSDs. "This integration of the entire industry chain maximizes the performance and stability of our products."

      It is understood that in the past two years, Xi'an Institute of Samsung Electronics has contributed a lot to the development of ODCC storage standards and worked with other domestic manufacturers to lead the development and promotion of test standards for the storage industry in domestic data centers. In response, Samsung said it will continue to work closely with ODCC in the future to support ODCC's SSD standardization activities in China and promote the various specifications and standardization results formulated by ODCC to the domestic SSD users.

      "At the same time, we will introduce more new technologies such as HBM, DDR5, Z-SSD, Key-Value SSD to domestic customers and plan to strengthen cooperation with BAT and many domestic server vendors so that customers can better understand Samsung Memory and SSD product advantages. "
