Claim 6:
7. A method for operating a memory system, comprising:
transmitting a command to a memory device for a data input/output operation;
performing the data input/output operation that changes data within at least one memory group in a memory device including a plurality of memory groups, each memory group including a plurality of non-volatile memory cells;
receiving a response, subject to the command and output from the memory device, the response including a result of the data input/output operation;
performing, based on the response, a second determination regarding whether the data input/output operation has succeeded or failed;
receiving a status data, regarding the at least one memory group, output from the memory device in response to the data input/output operation, the status data including a current operation information, regarding the at least one memory group for which data was changed during the data input/output operation;
comparing the status data with a physical to logical (P2L) map data item associated with the data input/output operation to perform a first determination regarding whether the data input/output operation has succeeded or failed;
determining whether the data input/output operation has succeeded or failed based on both the first determination and the second determination; and
updating a logical to physical (L2P) map data item based on the P2L map data item according to the first determination and the second determination regarding whether the data input/output operation has succeeded or failed.
