For small and large page NAND devices, the data is typically organized as follows:
Small page NAND FLASH (factory)
Bytes 0 - 511 : Main data payload area
Bytes 512 - 515 : Spare data area, 4 bytes
Bytes 516 - 517 : Factory bad block marker area (typical)
Bytes 518 - 527 : Spare data area, 10 bytes
Large page NAND FLASH (factory)
Bytes 0 - 2047 : Main data payload area
Bytes 2048 - 2048 : Factory bad block marker area (typical)
Bytes 2049 - 2111 : Spare data area, 63 bytes
The LPC32x0 MLC NAND controller uses the following storage approach when used with ECC:
Small page NAND FLASH, MLC NAND controller with ECC
Bytes 0 - 517 : Main data payload area
Bytes 518 - 527 : ECC data area
Large page NAND FLASH, MLC NAND controller with ECC
Bytes 0 - 517 : Main data payload area, subpage 1
Bytes 518 - 527 : ECC data area, subpage 1
Bytes 528 - 1045 : Main data payload area, subpage 2
Bytes 1046 - 1055 : ECC data area, subpage 2
