In order to achieve such densities with such a relatively low stack, Micron placed the logic under the memory array as shown in the diagram above. Micron’s first 3D NAND product will feature a 32-layer stack which provides up to 256Gb per die when used in a MLC (Multi-Level Cell) configuration and 384Gb per die in a TLC (Triple-Level Cell) configuration. Unfortunately, floating gate technology is more susceptible wearing out than CTF so Micron’s 3D NAND won’t be significantly more durable than 2D planar NAND, but it also shouldn’t be any less durable than 2D planar NAND as well. Rather than use new CTF, or Charge Trap Flash, technology, Micron continues to utilize their tried and true floating gate design. Micron’s 3D NAND is quite different compared to what everyone else is doing in the industry. The biggest difference is its core technology. That said, they’re still the second company to release a product based on 3D NAND product, so I guess they’re doing pretty well compared to the rest of the market. Micron first announced their upcoming 3D NAND back in late 2014 and it’s quite literally taken almost 2 years to develop into an actual consumer product. The newest development with the Crucial MX300 SSD is that it employs the use of Micron’s new 3D TLC NAND. Like previous 2D planar NAND, Micron 3D TLC NAND is a joint development between Intel and Micron and has been several years in the making.

Following the same strategy Crucial has taken since they first launched SSDs to the consumer market, Crucial’s new MX300 SSD will be aimed squarely at the mainstream SSD market. Micron, being one of the world’s largest NAND producers is stepping up in a big way with their latest Crucial branded SSD, the Crucial MX300. In a recent report by analyst firm TrendFocus, Samsung owns a staggering 40.8% share of total SSDs shipped and their 3D NAND accounts for nearly all of the 17% of all NAND shipped today.Īs such, we know that people want 3D NAND and if you’re a NAND maker without a 3D NAND product, it’s about time to step up your game. Crucial’s First 3D TLC SSDįor over two years, Samsung has been the only mass manufacturer of 3D NAND and being the first to market SSDs with the new technology, they’ve reaped some serious rewards.
