Samsung Electronics, the world leader in advanced memory technology, today unveiled an array of next-generation memory and storage technologies during Flash Memory Summit 2022, held at the Santa Clara (California) Convention Center, August 2-4. In a keynote titled “Memory Innovations Navigating the Big Data Era,” Samsung spotlighted four areas of technological advancement driving the big data market — data movement, data storage, data processing and data management — and revealed its leading-edge memory solutions addressing each field.

Petabyte Storage: Maximizing Server Utilization

To maximize data center efficiency in an increasingly data-driven world, Samsung introduced a next-generation storage technology, ‘Petabyte Storage.’ The new solution will allow a single server unit to pack more than one petabyte of storage, enabling server manufacturers to sharply increase their storage capacity within the same floor space with a minimal number of servers. High server utilization will also help to lower power consumption.

Memory-Semantic SSD: AI- and ML-Optimized Storage

Samsung announced its ‘Memory-semantic SSD’ that combines the benefits of storage and DRAM memory. Leveraging Compute Express Link (CXL) interconnect technology and a built-in DRAM cache, Memory-semantic SSDs can achieve up to a 20x improvement in both random read speed and latency when used in AI and ML applications. Optimized to read and write small-sized data chunks at dramatically faster speeds, Samsung’s Memory-semantic SSDs will be ideal for the growing number of AI and ML workloads that require very fast processing of smaller data sets.

Telemetry: Enabling More Reliable Data Center Management

As SSDs become more widely adopted in data centers, technology to manage these storage drives with the highest degree of reliability is becoming increasingly critical. Samsung’s telemetry technology gathers human-readable metadata from key components inside customers’ SSDs such as NAND flash and DRAM as well as SSD controllers and firmware. Based on this broad set of telemetry information, data centers can detect and prevent any potential problems ahead of time, enabling a more reliable and efficient operation.

Updates to Prior Milestones

Additionally, Samsung informed its keynote audience of important product updates to previously-announced mobile storage and high-performance SSD milestones.

The industry’s first UFS 4.0 mobile storage, developed by Samsung in May, is scheduled to enter mass production this month. The new UFS 4.0 will be a critical component in flagship smartphones that require large amounts of data processing for features like high-resolution images and graphics-heavy mobile games, and will later be used in mobility, VR and AR.

Samsung also announced market availability of two enterprise SSDs. Its PM1743, a CES 2022 Innovation Awards honoree, is the industry’s first PCIe 5.0 SSD, while the PM1653 is the first 24G SAS SSD, both now in mass production. The company further highlighted its paradigm-shifting SmartSSD and CXL DRAM, which have been designed to avoid bottlenecks in current memory and storage architectures.

“The IT industry is facing a new set of challenges brought on by the explosive growth in big data, and this underscores the importance of a robust, cross-industry ecosystem,” said Jin-Hyeok Choi, keynote speaker and executive vice president of Memory Solution & Product Development at Samsung Electronics. “We are committed to developing transformative memory technologies that can bring far-reaching changes in how we move, store, process and manage data for future AI, ML and HPC applications, as we navigate these challenging tides together with industry partners.”

Samsung Electronics, the world leader in advanced memory technology, today announced that it has begun volume production of 64-layer, 256Gb V-NAND flash memory for use with an expanding line-up of storage solutions for server, PC and mobile applications.

Since Samsung began producing the industry’s first SSD based on 64-layer 256Gb V-NAND chips in January for key IT customers, it has been working on a wide range of new V-NAND-based mobile and consumer storage solutions. These include embedded UFS memory, branded SSDs and external memory cards, which the company plans to introduce later this year.

To solidify its competitive edge in the memory market, Samsung intends for its volume production of the 64-layer V-NAND chip, which is widely referred to as 4^th generation V-NAND, to cover more than 50 percent of its monthly NAND flash production by year end.

“Following a long commitment to innovative technology, we will continuously push the limits of generations of industry-first V-NAND production, in moving the industry closer to the advent of the terabit V-NAND era,” said Kye Hyun Kyung, Executive Vice President of the Flash Product and Technology team, Memory Business at Samsung Electronics. “We will keep developing next-generation V-NAND products in sync with the global IT industry so that we can contribute to the timeliest launches of new systems and services, in bringing a higher level of satisfaction to consumers.”

The Samsung 64-layer 3-bit 256Gb V-NAND features a data transfer speed of 1Gbps (gigabit per second), which is the fastest among currently available NAND flash memory. Also, the V-NAND has the industry’s shortest page program time (tPROG)* of 500 microseconds (㎲) among NAND flash memory, which is about four times faster than that of a typical 10-nanometer (nm) class, planar NAND flash memory and approximately 1.5 times faster than that of Samsung’s fastest 48-layer 3-bit 256Gb V-NAND flash. With today’s ample supply of leading-edge V-NAND products, Samsung expects that the industry will now focus more on the high performance and reliability of memory storage, rather than immerse itself in a chip scaling race.

The new 64-layer 256Gb V-NAND provides more than a 30 percent productivity gain, compared to the 48-layer 256Gb V-NAND that preceded it. In addition, the 64-layer V-NAND has a 2.5V input voltage for its circuits, which leads to approximately 30 percent greater energy efficiency than the 3.3 volts that 48-layer V-NAND used. Also, the reliability of the new V-NAND cell increased by about 20 percent compared to its predecessor.

Samsung enabled these improvements by tackling a diversity of challenges that appear in the advanced V-NAND manufacturing process. Chief among them were realizing multi-billion channel holes that penetrate several dozen layers of cell-arrays, and minimizing the loss of electrons from about 85.3 billion cells.

As the layers of cell arrays increase, the level of technological difficulty also increases, especially in making the channel holes homogeneous in their shape from the top to the bottom layer, and in properly dispersing the weight of all the layers to improve the stability of the channel holes.

Another challenge that Samsung overcame was to realize 64 layers of cell arrays based on 3D CTF (charge trap flash) structure and uniformly cover the inner side of each channel hole with an atomically thin, non-conductive substance. This led to the creation of smaller cells with improved performance and reliability.

Based on 15 years of research into its proprietary V-NAND 3D structure, Samsung has formed the basis for more than 500 patents related to essential technological findings, and filed applications for them in many countries including Korea, the U.S. and Japan. Based on its success with 64-layer V-NAND, Samsung has secured the fundamental technology that it needs in the future to produce V-NAND chips with one terabit capacity and more, by stacking over 90 layers of cell arrays.

Samsung Electronics, the world leader in advanced memory technology, announced that it has begun mass producing the industry’s first 256-gigabit (Gb), three-dimensional (3D) Vertical NAND (V-NAND) flash memory based on 48 layers of 3-bit multi-level-cell (MLC) arrays for use in solid state drives (SSDs).

“With the introduction of our 3rd generation V-NAND flash memory to the global market, we can now provide the best advanced memory solutions, with even higher efficiency based on improved performance, power utilization and manufacturing productivity, thereby accelerating growth of the high-performance and the high-density SSD markets,” said Young-Hyun Jun, President of the Memory Business at Samsung Electronics. “By making full use of Samsung V-NAND’s excellent features, we will expand our premium-level business in the enterprise and data center market segments, as well as in the consumer market, while continuing to strengthen our strategic SSD focus.”

Samsung’s new 256Gb 3D V-NAND flash doubles the density of conventional 128Gb NAND flash chips. In addition to enabling 32 gigabytes (256 gigabits) of memory storage on a single die, the new chip will also easily double the capacity of Samsung’s existing SSD line-ups, and provide an ideal solution for multi-terabyte SSDs.

Samsung introduced its 2nd generation V-NAND (32-layer 3-bit MLC V-NAND) chips in August 2014, and launched its 3rd generation V-NAND (48-layer 3-bit MLC V-NAND) chips in just one year, in continuing to lead the 3D memory era.

In the new V-NAND chip, each cell utilizes the same 3D Charge Trap Flash (CTF) structure in which the cell arrays are stacked vertically to form a 48-storied mass that is electrically connected through some 1.8 billion channel holes punching through the arrays thanks to a special etching technology. In total, each chip contains over 85.3 billion cells. They each can store 3 bits of data, resulting 256 billion bits of data, in other words, 256Gb on a chip no larger than the tip of a finger.

A 48-layer 3-bit MLC 256Gb V-NAND flash chip consumes over a 30 percent reduction in power compared to a 32-layer, 3-bit MLC, 128Gb V-NAND chip when storing the same amount of data. During production, the new chip also achieves approximately 40 percent more productivity over its 32-layer predecessor, bringing much enhanced cost competitiveness to the SSD market, while mainly utilizing existing equipment.

Samsung plans to produce 3rd generation V-NAND throughout the remainder of 2015, to enable more accelerated adoption of terabyte-level SSDs. While now introducing SSDs with densities of two terabytes and above for consumers, Samsung also plans to increase its high-density SSD sales for the enterprise and data center storage markets with leading-edge PCIe NVMe and SAS interfaces.
