NOTE :

- BI: Bad block Information

>Host can use complete spare area except BI and ECC code area. For example,

Host can write data to Spare area buffer except for the area controlled by ECC logic at program operation.

>In case of ‘with ECC’ mode, MuxOneNAND automatically generates ECC code for both main and spare data of memory during program operation,

but does not update ECC code to spare bufferRAM during load operation.

>When loading/programming spare area, spare area BufferRAM address(BSA) and BufferRAM sector count(BSC) is chosen via Start buffer register as it is.
