characteristics:
1, the speed is slow, the market share is very high.
2, the quality of flash chip is very poor, basic is the use of black film.
3, JS are like sales, because the price is low.
Flash manufacturers do not need to compare, Samsung, Intel, Heidelberg, Toshiba are manufacturers. But there are SLC, MLC, TLC points.
SLC (Single-level Cell) is 1bit/cell, the speed of long life, the price is expensive (about MLC 3 times times more than t

S5PV210 Development Series seven NAND drive implementationsChess Boy 1048272975Nand Flash has the advantages of large capacity, fast rewriting speed, simple interface and so on, which is suitable for storage of large amount of data, which provides a cheap and effective solution for solid-state mass storage. A variety of electronic products such as mobile phone memory, SD card, u disk, etc. are using NAND flash storage, the author here on the NAND drive implementation as a simple introduction.1.
