Say goodbye to the days of having to decide on whether you want to purchase the 16 or 32 GB model of your device.

The same technology from the “stacked” 3D chips found in Intel’s new Haswell processors could be found in flash memory modules in flagship mobile phones by 2014, according to Samsung. The company has already stacked 24 ‘NAND’ modules on top of one another, which makes memory faster (and larger) than ever before experienced on a mobile device.

V-NAND chips start with 128 GB of memory and can go all the way up to 1 TB. The question of whether a phone has a micro-SD card slot will never be asked again!

You’re probably thinking that we’re years off from this reaching mobile phones— think again. Samsung has already sent out the technology to mobile phone makers to sample it, and reportedly is already prepared to produce them in mass quantities.

The V-NAND chips will most likely be found in SSD memory later this year, and will eventually make its way to the mobile device world by 2014. Sometimes we forget how fast technology is moving… Check out the presser after the break.

Samsung Starts Mass Producing Industry's First 3D Vertical NAND Flash
Samsung Electronics 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.
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.
