Abstract
Methods, systems, and devices for data compression for mapping tables are described. A memory system may store a table that includes mappings between a set of logical block addresses and a set of physical block addresses. The table may be stored to volatile memory of the memory system and each entry may include a subset of physical block addresses and one or more logical block addresses that correspond to the subset of physical block addresses. In some implementations, a quantity of the entries that each include the subset of physical block addresses and the one or more logical block addresses may be determined based on dividing the set of physical block addresses by a factor. Similarly, a size of the entries may be determined based on dividing the set of physical block addresses by the factor.
