• Manufacturer Part Number: kfm2g16q2a-deb8
• Description: 2gb Muxonenand A-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
MuxOneNAND2G(KFM2G16Q2A-DEBx)
MuxOneNAND4G(KFN4G16Q2A-DEBx)
Host can write data to Spare area buffer except for the area controlled by ECC logic at program operation.
DataS 1_3
but does not update ECC code to spare bufferRAM during load operation.
