FMC: Flexible Memory Controller NAND memory page size (without spare area) measured in bytes for 8-bit addressing or words for 16-bit addressing. NAND memory spare area size measured in bytes for 8-bit addressing or words for 16-bit addressing. NAND memory block size expressed in number of pages. NAND memory number of blocks. NAND memory number of planes. NAND memory plane size measured in number of blocks. NAND extra command needed for page reading mode. This parameter is mandatory for some NAND memories. Please check the read mode sequence in the NAND device datasheet.
