背景 1.2012年左右的数据SLC.MLC.TLC闪存芯片的区别:SLC = Single-Level Cell ,即1bit/cell,速度快寿命长,价格超贵(约MLC 3倍以上的价格),约10万次擦写寿命MLC = Multi-Level Cell,即2bit/cell,速度一般寿命一般,价格一般,约3000---10000次擦写寿命(2003)TLC = Trinary-Level Cell,即3bit/cell,也有Flash厂家叫8LC,速度慢寿命短,价格便宜,约500次擦写寿命,目…

BACKGROUND OF THE INVENTION Conventional NAND Flash memories move data in the background to write over an entire span uniformly. The background data movement is called wear leveling. A process performing the background data movement is often referred…

One of the problems with developing embedded systems is the detection of memory leaks; I've found three tools that are useful for this. These tools are used to detect application program errors, not kernel memory leaks. Two of these tools (mtrace and…

linux的NAND Flash驱动位于drivers/mtd/nand子文件夹下: nand_base.c-->定义通用的nand flash基本操作函数,如读写page,可自己重写这些函数 nand_bbt.c-->与坏块管理有关的函数和结构体 nand_ids.c-->nand_flash_ids[](芯片ID)和nand_manuf_ids[](厂商ID) nand_ecc.c-->软件ECC代码,若系统支持硬件ECC.则不用理会这个文件 pl353_nand.c-->…
