OPERATING METHOD OF MEMORY SYSTEM INCLUDING NONVOLATILE RANDOM ACCESS MEMORY AND NAND FLASH MEMORY

摘要

The present invention relates to a method of operating a memory system including a nonvolatile random access memory and a NAND flash memory. The operating method of the present invention may include receiving a read request of the NAND flash memory, performing a read in the NAND flash memory in response to the read request, and rereading the read from the NAND flash memory when the read is failed. And storing, again in the nonvolatile random access memory, path information associated with the read pass of the read.
