2Wire’s NAND Flash Error Correcting Code (ECC) | Hacking the 2Wire Earlier we developed TriMedia code to dump the contents of the NAND flash device on the 2Wire boards. [1] The diagram below illustrates the organisation of a NAND flash memory array. In addition to a main data page area (usually 512 bytes), NAND devices a
Raw NAND ECC - Texas Instruments Wiki Unlike OMAP35x/AM35x devices, DM/OMAPL13x/C674x/AM1xxx doesn't have GPMC or ECC support in ROM bootloader firmware. These device's EMIF hardware supports detection and correction for most of the devices (the ROM bootloader uses EMIF HW to ...

NOR型flash與NAND型flash的區别 - jinren1010的空間 快閃記憶體晶片讀寫的基本單位不同 應用程序對NOR晶片操作以“字”為基本單位。為了方便對大容量NOR快閃記憶體的管理,通常將NOR快閃記憶體分成大小為128KB或者64KB的邏輯塊,有時候塊內還分成扇區。讀寫時需要同時指定邏輯塊號和塊內偏移。
