BufferRAM and NAND array structure Block: 64KB+2KB 64pages NOTE: 1) The 1st word of spare area in 1st and 2nd page of every invalid block is reserved for the invalid block information by manufacturer. Please refer to page 59 about the details. 2) These words are managed by internal ECC logic. So it is recommended that the important data like LSN(Logical Sector Number) are written. 3) These words are reserved for the future purpose by manufacturer. These words will be dedicated to internal logic. 4) These words are for free usage. 5) The 5th, 6th and 7th words are dedicated to internal ECC logic. So these words are only readable. The other words are program- mable by command. 6) ECCm 1st, ECCm 2nd, ECCm 3rd: ECC code for Main area data 7) ECCs 1st, ECCs 2nd: ECC code for 2nd and 3rd word of spare area. 1st W ECCm 1st ECCm 2nd ECCm 3rd ECCs 1st ECCs 2nd LSB MSB LSB MSB 2nd W LSB MSB 3rd W LSB MSB 4th W LSB MSB 5th W LSB MSB 6th W LSB MSB 7th W LSB MSB 8th W LSB MSB Figure 3.
