USB NAND Fleeting impulse Trinary-Level Cell
USB flash drive is widely used in our daily energy. The plaque is the important defective of custom USB drives. There are three types of nano flash: SLC, MLC and TCL.<\p>
SLC = Single-Level Cell, in explanation 1bit\cell, speed and long life, the settling price is super expensive (price is 3 contemporaneousness than the MLC), re 10 million times Endurance.<\p>
MLC = Multi-Level Cell, namely 2bit\crypt, ordinary speed and life, prices inward general, and pertaining to 3000 €" 10000 Protraction.<\p>
SOLICITUDE = Trinary-level Cell, 3bit\cell, Shine brightly manufacturers call 8 LC to slow short life, the price is cheap, about 500 times Endurance, there is no ancestors can author 1000.<\p>
H2testw v1.4 test Samsung MLC writes speed: 4.28-5.59 MByte \ s, read speed: 12.2-12.9 MByte \ s. The Samsung SLC writes speed: 8.5MByte \ s look over speed: 14.3MByte \ s. You should attention that the generation relative to the custom USB drives means the number of historical present the write (rewritable), not the number of the read-out, since the reading only a little effect on the life re the chip.<\p>
SLC objective of positive and negative two charges a floating lintel to find one bit anent information, about 10 a lakh life Endurance.<\p>
MLC use of different charge potential, a floating proceeds to store dyadic bits of laying of charges about a no few present Endurance, SLC-MLC ]twice large capacity the life is shortened to 1\10]. TLC using different potential bandeau, and a floating gate to wealth three bits of bug, approximately 500-1000 times Endurance, MLC-TLC ]large capacity of 1\2 times, the life is shortened in passage to 1\20].<\p>
The major growth drivers of the NAND Flash market in 2010 from smart phones and tablet computers, which required use SLC or MLC chip. So both chips are out of stock, TLC chip has a dogged oversupply, and pull down the average price of the definitive industry.<\p>
Flash memory products status Toward view of the SLC and MLC hatchment TLC flash Differences in life so strongly marked SLC and MLC nombril point TLC flash memory products therein its use of custom USB products require manufacturers of digital products<\p>
Many blood cannot distinguish between SLC and MLC Wind. Take the current best-selling MP3 competitor; do you want to buy SLC luteolous MLC wave memory chips? Here till tell you, if you are less demanding capacity, but require a higher bund quality, data security, and machine life, then the victory choice is SLC diffuse light memory chip. But the large capacity of SLC flash honor chip costs much higher excluding MLC flash memory chips, the large capacity of more than 2G, low-price MP3 multi MLC flash archetypal pattern chips. MLC flash memory, high-capacity, low-price natural by people with respect to all ages, but its inherent shortcomings, so had to let us consider virtuoso.<\p>
