1. A memory system comprising:
a storage medium including a plurality of physical regions; and
a controller configured to map logical regions which are configured by a host device, to the physical regions, and configured to perform in response to a write request for a target logical region, a write operation on a physical region mapped to the target logical region,
wherein the controller is further configured to update in response to the write request, a write status corresponding to the target logical region within a write status table, and
wherein the controller is further configured to update all write statuses in the write status table to a first status directly in response to a determination that during a booting operation there is no abnormal power-off right before the booting operation.
