MuxOneNAND2G(KFM2G16Q2A-DEBx) - 171 - FLASH MEMORY MuxOneNAND4G(KFN4G16Q2A-DEBx) 7.2 Boot Sequence One of the best features MuxOneNAND has is that it can be a booting device itself si nce it contains an internally built-in boot loade r despite the fact that its core architecture is based on NAND Flash. Thus, MuxOneNAND does not make any additio nal[...]
