Abstract: Disclosed is a technology for storing snapshot images capable of maximizing the reading performance of an SD/MMC card at the time of recovering the snapshot images and minimizing the booting time of a system. A method for storing snapshot images includes: preparing the snapshot images, attempting to allocate continuous reference blocks, in which a number of blocks corresponding to the predetermined number of reference blocks is continuous in a non-volatile memory unit, storing the snapshot images in the allocated continuous reference blocks when the allocation of the continuous reference blocks succeeds, and preparing the snapshot image storage information as a swap table and storing the prepared swap table in the non-volatile memory unit.
