• Description: 2gb Muxonenand M-die
• Manufacturer: Samsung Semiconductor, Inc.

NOTE:
- BI: Bad block Information
>Host can use complete spare area except BI and ECC code area. For example,
>In case of ’with ECC’ mode, MuxOneNAND automatically generates ECC code for both main and spare data of memory during program operation,
>When loading/programming spare area, spare area BufferRAM address(BSA) and BufferRAM sector count(BSC) is chosen via Start buffer register

DataS 1_3
Host can write data to Spare area buffer except for the area controlled by ECC logic at program operation.
but does not update ECC code to spare bufferRAM during load operation.
