Abstract: The present specification discloses a digital device for performing a hibernation booting process and a control method therefor. Here, the digital device according to an embodiment of the present invention comprises: a first memory; a second memory storing a snapshot image generated on the basis of pieces of page data of the first memory; and a control unit for generating the snapshot image, wherein the control unit primarily deduplicates duplicated page data in the first memory and selectively secondarily deduplicates duplicated page data by comparing the duplicated page data with the snapshot image prestored in the second memory, wherein data fragmentation is minimized through the secondary deduplication step.
