Abstract
Methods, systems, and devices for flexible information compression at a memory system are described. For example, a memory system may compress information in a change log to reduce the frequency of transfers of one or more mappings between volatile memory and non-volatile memory. The memory system may compress information associated with a sequence of sequentially-indexed addresses by storing the information associated with those addresses at a pair of entries in the change log. The memory system may additionally switch between a first operating mode associated with identifying sequentially-indexed addresses and generating compressed entries, and a second operating mode associated with generating entries of the change log for each address received in commands.
