1 OVERVIEW
Recently NOR Flash memory price has increased and price for DRAM and a NAND Flash memory is moderately
placed. This is the reason why customer prefer to execute the boot code on a NAND Flash and execute the main
code on DRAM.
S5PC100 boot code is executed on an external NAND Flash memory. The boot code copies NAND Flash content
to DRAM. The hardware ECC is used to check data validity of the NAND Flash. After the NAND Fash content is
copied to DRAM, main program is executed on DRAM.
