The advantages, disadvantages and differences of SLC, MLC and TLC flash types in U disk

- May 23, 2018-

  The TLC chip technology of SLC, MLC and TLC X3 (3-bit-per-cell) architecture is an extension of MLC and TLC technology. The earliest NAND Flash technology architecture is SLC (Single-Level Cell), the principle is in 1 memory storage. One bit of data is stored in a cell. After the MLC (Multi-Level Cell) wood retractable box shape usb stick.jpgtechnology is completed, the architecture evolves into a memory storage unit to store 2 bits. In 2009, the TLC architecture was officially launched, representing a memory storage unit that can store 3 bits, and the cost was further reduced. Like the previous wave of SLC technology to MLC technology trends, the NAND Flash maker Toshiba triggered the war. Samsung Electronics quickly joined the battle, resulting in mass production of the entire TLC technology and its application. On the end product. Although the TLC chip has a large storage capacity and a low cost, its performance is also greatly reduced, so it can only be used in low-end NAND Flash-related products, such as low-speed flash memory cards, microSD memory cards, or SD cards. The technology thresholds such as embedded century liquid applications, smart phones, and solid state drives (SSDs) are high. For applications that require NAND Flash performance to be high-speed and free from errors, SLC or MLC chips must be used.

Therefore, both chips are out of stock, and the TLC chip is continuously oversupply and will The average price of the entire industry was pulled downwards, which caused the market adjustment agency iSuppli to report a rare reduction in the market's global NAND Flash production value in the second quarter of 2010, which fell from US$4.3 billion in the first quarter of 2010 to US$4.1 billion. Reduced by 6.5%. Differences between SLC, MLC, and TLC flash memory chips used in U disk MP3:


  SLC = Single-Level Cell, ie, 1 bit/cell, fast speed, long life, expensive (about 3 times more than MLC), about 100,000 flash life MLC = Multi-Level Cell, 2 bit/cell, speed General life, general price, about 3000 - 10,000 times the life of TLC = Trinary-Level Cell, that is, 3bit / cell, there are Flash manufacturers called 8LC, slow life, low speed, low cost, about 500 erase life, At present, there are no manufacturers that can do it 1000 times.
