Samsung SSD 840 Series Product Story 3-bit/cell MLC NAND Flash

[quote=www.samsung.com/global/business/semiconductor/minisite/SSD/us/html/about/MlcNandFlash.html]Introduction: A Breakthrough in Technology
With the 840 Series SSD, Samsung is bringing the very first 3-bit/cell consumer SSD to market. Although
it is a natural progression from MLC NAND, many are curious about this new NAND, which is sometimes
referred to as TLC NAND.
The advent of 3-bit/cell MLC(Multi Layer Cell) NAND technology in consumer SSDs represents an exciting
evolution of NAND technology. Advances in process and controller technology have allowed Samsung to
design a new generation of MLC NAND chips that contain 3-bits/cell as opposed to the traditional 2-bits/
cell that regular MLC NAND contains. While 3-bit/cell NAND has been around in low endurance, low
performance consumer applications for years (e.g. USB flash drives, memory cards, some digital devices,
etc.), this is the first time the technology has been applied to a high endurance, high performance
application like SSDs.
