Power batteries are the most important part of the movement, quality batteries basically represents the quality of mobile power products, so this is the first of several carried out. Rechargeable lithium-ion batteries on the market there are these types of polymer batteries, aluminum batteries, electrical steel core brand SD cards agent, cylindrical metal batteries (the most common is the 18650 cylindrical cells), aluminum Shell batteries mainly used in mobile phone batteries, low grade steel batteries basically do not know what you are 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 following the life of MLC write speeds are generally shorter than .MLC wafer longer half life than MLC, made out of SD card U disk TF card the rate of about 6MB, so imagine the final SLC long life, speed CLASS10, half the speed required to read and write must use SLC or reach equipment. NAND Flash controller chip to improve endurance, SSD improve life with the constant development of the original manufacturing process, NAND Flash production costs fell Toshiba SD card factory, Endurance reduce Shenzhen factory wholesale SD card, requires control chip ECC error correction capability of the higher initial .NAND Flash SLC Endurance up to 10 million times, just use 1-4bit ECC, 20nm process MLC Endurance reduced to 3000--10000 times required ECC up to 16-40bit, to only 500 TLC Endurance -1000 times, to be 72bit even higher ECC.NAND Flash in SLC period, the 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 the life of Kingston SD card factory |. famous electronic (online consultation) | SD card factory is supplied by Shenzhen Electronics Co., Ltd.
