Abstract
A journal replay method of a storage device includes loading metadata into a buffer memory, initializing a first trim bit and a second trim bit of a trim table to a clear state, the first and second trim bits indicating a replay status of respective first and second trim journals in first and second address ranges of the metadata, updating first metadata corresponding to the first address range by replaying the first trim journal, setting the first trim bit corresponding to the replayed first trim journal to a set state, determining whether the second address range of the second trim journal overlaps the first address range, and skipping replay of the second trim journal based on a state of the first trim bit based on determining that the second address range overlaps the first address range.
