DATA STORAGE DEVICE AND OPERATING METHOD THEREOF
First Claim
1. A data storage device comprising:
- a nonvolatile memory device including a memory block, to which a write operation is interrupted and not completed due to at least one time occurrence of a sudden power-off (SPO) of the data storage device, wherein the memory block includes at least one first valid page group including one or more valid pages caused before the interruption and at least one invalid page group having one or more invalid pages caused by the interruption; and
a controller suitable for;
writing at least one physical address-to-logical address (P2L) list for the first valid page group into the invalid page group after power-on of the data storage device following the SPO, andrecovering an address mapping table for the memory block based on the P2L list after completion of the write operation to the memory block.
