Electronic device including non-volatile memory, and non-volatile memory management method thereof

A memory management method of an electronic device including a non-volatile memory, the method comprising:

• monitoring, by a file system (FS) manager, a free space log corresponding to a first free space of the non-volatile memory in a log stream generated to manage at least one file stored in the non-volatile memory;
• transmitting a compression request from the FS manager to a file system managing the log stream based on a size of the first free space indicated in the free space log being less than a first reference value;
• selecting, by the file system, a first segment including an uncompressed node block log from the log stream;
• selecting, by the file system, at least one uncompressed node block log included in the selected segment;
• storing, by the file system, a compressed node block log obtained by compressing the at least one compressed node block log in a last segment of the log stream;
• storing, by the file system, a compressed node block corresponding to the compressed node block log in the first free space of the non-volatile memory;
• and
• indicating, by the file system, a second free space of the non-volatile memory secured through compression of the at least one node block log as a reserved block log in the log stream based on a compression end condition being satisfied.
