Leveraging Processor-supplied SRAM to Facilitate OneNAND Bootloaders

NAND flash memory densities for device-resident memory are increasing—and the price decreasing—with designers desiring to remove NOR flash devices from their design, and instead boot their processors from less expensive NAND. Due to the architecture of NAND flash memory devices, NAND flash cannot be used to boot processors unless the processor or the system contains some additional enabling logic. This white paper discusses the OneNAND bootloader, including limitations and Implementation.
