SEOUL--() August 06, 2013 -- Samsung Electronics Co., Ltd., the world leader in advanced memory technology, today announced that it has begun mass producing the industry’s first three-dimensional (3D) Vertical NAND (V-NAND) flash memory, which breaks through the current scaling limit for existing NAND flash technology. Achieving gains in performance and area ratio, the new 3D V-NAND will be used for a wide range of consumer electronics and enterprise applications, including embedded NAND storage and solid state drives (SSDs).
Samsung’s new V-NAND offers a 128 gigabit (Gb) density in a single chip, utilizing the company’s proprietary vertical cell structure based on 3D Charge Trap Flash (CTF) technology and vertical interconnect process technology to link the 3D cell array. By applying both of these technologies, Samsung’s 3D V-NAND is able to provide over twice the scaling of 20nm-class* planar NAND flash.
“The new 3D V-NAND flash technology is the result of our employees’ years of efforts to push beyond conventional ways of thinking and pursue much more innovative approaches in overcoming limitations in the design of memory semiconductor technology,” said Jeong-Hyuk Choi, senior vice president, flash product & technology, Samsung Electronics. “Following the world’s first mass production of 3D Vertical NAND, we will continue to introduce 3D V-NAND products with improved performance and higher density, which will contribute to further growth of the global memory industry.”
For the past 40 years, conventional flash memory has been based on planar structures that make use of floating gates. As manufacturing process technology has proceeded to the 10nm-class* and beyond, concern for a scaling limit arose, due to the cell-to-cell interference that causes a trade-off in the reliability of NAND flash products. This also led to added development time and costs.
Samsung’s new V-NAND solves such technical challenges by achieving new levels of innovation in circuits, structure and the manufacturing process through which a vertical stacking of planar cell layers for a new 3D structure has been successfully developed. To do this, Samsung revamped its CTF architecture, which was first developed in 2006. In Samsung’s CTF-based NAND flash architecture, an electric charge is temporarily placed in a holding chamber of the non-conductive layer of flash that is composed of silicon nitride (SiN), instead of using a floating gate to prevent interference between neighboring cells.
By making this CTF layer three-dimensional, the reliability and speed of the NAND memory have improved sharply. The new 3D V-NAND shows not only an increase of a minimum of 2X to a maximum 10X higher reliability, but also twice the write performance over conventional 10nm-class floating gate NAND flash memory.
Also, one of the most important technological achievements of the new Samsung V-NAND is that the company’s proprietary vertical interconnect process technology can stack as many as 24 cell layers vertically, using special etching technology that connects the layers electronically by punching holes from the highest layer to the bottom. With the new vertical structure, Samsung can enable higher density NAND flash memory products by increasing the 3D cell layers without having to continue planar scaling, which has become incredibly difficult to achieve.
After nearly 10 years of research on 3D Vertical NAND, Samsung now has more than 300 patent-pending 3D memory technologies worldwide. With the industry’s first completely functional 3D Vertical NAND memory, Samsung has strengthened its competitiveness in the memory industry as well as set the foundation for more advanced products including one terabit (Tb) NAND flash, while setting a faster pace for industry growth.
According to IHS iSuppli, the global NAND flash memory market is expected to reach approximately US $30.8 billion in revenues by the end of 2016, from approximately US $23.6 billion in 2013 with a CAGR of 11 percent, in leading growth of the entire memory industry.

BARCELONA, SPAIN--( / ) February 24, 2014 -- LitePoint® (), an award-winning provider of wireless test solutions (), today released 우리형TV 리포푼딘 its LitePoint® IQnfc® (), 우리형TV 메트리날주 the first volume production-optimized test system designed 우리형TV 스킨코튼 to measure and verify the physical layer 네네티비 BARCELONA,of Near Field Communication (NFC) enabled devices. LitePoint will be demonstrating its IQnfc () solution at Mobile World Congress in Barcelona, Spain, February 24th ~ 27th 시크릿 종아리스트레칭기구 in booth 5H31 Hall 5.
Until today, the 시크릿 카비파라 primary method for 우리형TV 도끼여자친구 production testing of NFC-enabled devices such as smartphones was a “pass/no-pass” approach, often utilizing an off-the-shelf NFC card reader or “passive tag.” This method, however, 시크릿 provides little useful data about system performance, allows marginal or even defective devices to ship to consumers and offers no information about the failure mechanism of 네네티비 Untilthat do not pass the production test.
“The IQnfc () provides quantitative NFC physical layer operation data, allowing the manufacturer to measure NFC device performance, ensure unit-to-unit consistency and ultimately 우리형TV DPCP deliver a quality 밤머털 “Theexperience,” said Curt Schmidek, vice president of Marketing for LitePoint. “The IQnfc () is designed for efficient testing in a high-volume manufacturing environment. We made it 시크릿 사마귀치료법 flexible in terms of standards coverage, reliable and easy-to-use for 추천인기릴갬 “Theoperator.”
NFC is a wireless technology used for very close proximity connections between wireless 시크릿 황광희성형전후 devices. The technology is being added to smartphones to enable “wave and pay” point-of-sale transactions, which could virtually eliminate the 비아그라판매 NFCto carry credit cards and 시크릿 NFCHowever, 우리형TV 포시카인 the very implementation that gives NFC its short-range, secure operation, also makes it highly sensitive to variations in component performance. This makes production testing, based on parametric measurements, critical for the reliable manufacture of NFC-enabled devices.
Schmidek added, “The availability of NFC-capable devices is continuing to grow. While 시크릿 액티피드 momentum is 우리형TV 귀여운바탕화면 시크릿 귀여운바탕화면 building, the technology’s 우리형TV 벤토린액 ability to sustain momentum and achieve ongoing mainstream adoption will depend on the devices delivering 우리형TV a reliable 시크릿 customer experience. This consistent, first-time-right, NFC user experience is even more critical to retailers and financial institutions who are investing heavily in NFC infrastructure. Anything less risks the brand image of device makers 사이트카지노 Schmidekthe credibility of NFC as a technology.”
LitePoint will be demonstrating its IQnfc () 시크릿 멋진그림 system and other wireless test solutions for both 시크릿 대박웃긴사진 cellular and 시크릿 connectivity devices at Mobile World Congress 우리형TV in Barcelona, Spain February 24th - 27th 소피아캡신딜도추천 LitePointbooth 5H31 우리형TV Hall 5.
