Abstract

Methods, systems, and devices for a sorted change log for physical page table compression are described. A mapping between a logical address and a physical address may be stored in a change log buffer. The mapping may be stored at a location of the change log buffer based on the logical address of the mapping relative to logical addresses of other mappings stored in the change log buffer. Based on storing mappings in the change log buffer based on logical addresses of the mappings, a set of mappings in the change log may include a set of sequentially-indexed logical addresses. A compressed entry for a logical-to-physical table may be generated based on the set of mappings.
