摘要:Multiple copies of firmware code for controlling operation of a non-volatileflash memory system are stored at different suitable locations of the flash memory of amemory system. A map of addresses of these locations is also stored in the flashmemory. Upon initialization of the memory system, boot code stored in the memorycontroller is executed by its microprocessor to reference the address map and load onecopy of the firmware from the flash memory into a controller memory, from which it maythen be executed by the microprocessor to operate the memory system to store andretrieve user data. An error correction code (ECC) is used to check the data but the bestportions of the two or more firmware copies stored in the flash memory are used toreduce the need to use ECC. The firmware code may be stored in the flash memory intwo-states when user data is stored in the same memory in more than two-states.
