Do you know what is TLC, MLS, SLC, three representatives of the life of this chip, the speed, TLC is the worst wafer made out of SD card U disk TF card speed is generally in CLSS4 (CLASS4 refers 4MB or less MLC write speed of life is generally shorter than .MLC wafer longer half life than MLC toy dedicated SD card, SD card made out of U disk TF card speed is about 6MB, so imagine the SLC final Long life, speeds up CLASS10, half the speed required to read and write must use SLC or reach equipment. NAND Flash controller chip to improve endurance, increase SSD life as the original manufacturing process continues to develop, NAND Flash production costs decline, Endurance reduce required ECC error correction ability to control the chip, the higher the initial .NAND Flash SLC Endurance up to 10 million times, just use 1-4bit ECC, 20nm process MLC flash reduce life to 3000--10000 times required ECC up to 16-40bit, the TLC Endurance only 500 - 1000 times, need 72bit even higher ECC.NAND Flash SLC period in a digital camera SD card, control chip only needs to use error correction capability is not strong Hamming code algorithm, MLC requires a higher error correction capability BCH code, TLC or 3D Correction technology starting from BCH to low-density parity check code LDPC transition to strengthen life. 16GB high capacity SanDisk TF card TF card, also known as T-Flash card, full name: TransFLash, also known as: Micro SD, jointly developed by Motorola and SANDISK, launched in 2004, is an ultra-compact card (11 * 15 * 1MM). about 1/4 of SD card, you can count the smallest memory card the .Trans-Flash Card SD Card products for the members of one, with SD adapter phone recorder dedicated SD card, compatible with any SD card reader is, after TF card through SD card converter, when the SD card .T-Flash card is the smallest flash memory card market, SD card, suitable for many multimedia applications .Trans-flash products designed with SD infrastructure, SD Association at the end of 2004 officially changed its name to Micro SD, SD products has become a member of the Buddhist dedicated SD card |. famous electronic (online consultation) |.
