Samsung Commences Mass Production of 9th Gen V-NAND: Revolutionary 1Tb 3D TLC NAND


April 27, 2024

Samsung Electronics has begun mass production of their 9th generation V-NAND memory, boasting impressive data transfer rates and advancements in cell size miniaturization and string stacking, solidifying their position as a leader in the storage market.

  • Mass production of 9th gen V-NAND marks another milestone in Samsung's dominance in the storage market.
  • 50% improvement in bit density compared to its predecessor.
  • Advanced technologies such as string stacking and channel hole etching improve manufacturing productivity and performance.


Samsung Electronics has officially begun mass production of its 9th generation V-NAND memory, marking another milestone in the company’s dominance in the storage market. The new 3D TLC NAND memory, based on Samsung’s latest NAND tech, offers a 1 Tb capacity using a triple-level cell (TLC) architecture and boasts impressive data transfer rates of up to 3.2 GT/s.

While Samsung has not disclosed the exact number of layers in their 9th gen V-NAND, industry insiders speculate that it could be around 290 layers, surpassing its competitors. What Samsung has confirmed is that this new generation offers a significant 50% improvement in bit density compared to its predecessor, thanks to advancements in cell size miniaturization and enhanced memory cell technologies.

One interesting detail revealed in Samsung’s announcement is the company’s use of string stacking, referred to as their “double-stack structure.” While it is believed that Samsung employed this technique in their 8th gen NAND as well, this is the first time they have publicly acknowledged it. String stacking will play a crucial role in future NAND development as manufacturers strive to add more layers to their dies.

Another noteworthy technological enhancement in the 9th gen V-NAND is Samsung’s advanced ‘channel hole etching’ technology, which enables efficient drilling through multiple layers. This process improves manufacturing productivity and facilitates the creation of electron pathways within the double-stack structure.

In terms of performance, the latest V-NAND introduces a faster NAND flash interface called Toggle DDR 5.1, which boosts peak data transfer rates by 33% to 3.2 GT/s. Additionally, Samsung claims a 10% reduction in power consumption for the 9th gen V-NAND, although specific conditions for this improvement are not provided.

Samsung’s launch of the 1Tb TLC V-NAND will be followed by the release of a quad-level cell (QLC) model later this year, further expanding their solid-state drive (SSD) products.

SungHoi Hur, Head of Flash Product & Technology of the Memory Business at Samsung Electronics, expressed excitement about the company’s latest V-NAND, stating that it will drive future applications forward and meet the demands of the AI generation. Samsung’s continuous innovation in cell architecture and operational schemes positions them as leaders in the high-performance, high-density SSD market.

With the mass production of their 9th generation V-NAND memory, Samsung solidifies its position as a key player in the storage industry, offering technology that pushes the boundaries of what is possible in NAND flash solutions.

Technology Explained


NAND: NAND technology is a type of non-volatile memory that is used in many computer applications. It is a type of flash memory that is used to store data in a non-volatile manner, meaning that the data is not lost when the power is turned off. NAND technology is used in many computer applications, such as solid-state drives, USB flash drives, digital cameras, and memory cards. It is also used in many embedded systems, such as cell phones, tablets, and other consumer electronics. NAND technology is a reliable and cost-effective way to store data, making it a popular choice for many computer applications.


SSD: A Solid State Drive (SSD) is a modern data storage device that employs flash memory technology to store data electronically. Unlike traditional hard disk drives (HDDs), SSDs have no moving parts, resulting in significantly faster read and write speeds. This leads to quicker boot times, faster application loading, and smoother overall system performance. SSDs are known for their durability, shock resistance, and energy efficiency, making them ideal for laptops, ultrabooks, and other portable devices. They come in various form factors, including 2.5-inch, M.2, and PCIe cards, and are favored for their reliability, quiet operation, and reduced heat generation
