Abstract

See full text

Disclosed is a method for storing data of a log-structured file system (LFS), which does not separately store segment summary information (SS) and segment usage information (SU) but makes a checkpoint be included in a checkpoint record and written upon writing the checkpoint to improve write performance for a flash memory by decreasing the number of metadata to be written in a flash page.
