Abstract: Methods, systems, and devices for techniques for logical-to-physical information compression are described. In some cases, a memory system may compress a logical-to-physical (L2P) mapping to expand the quantity of physical addresses mapped by the L2P mapping.

Additionally, the memory system may include an indication of a starting logical address corresponding to the starting physical address in the compressed entry. To identify a physical address within the compressed entry, the memory system may determine an offset between a logical address corresponding to the physical address and the starting physical address using the indication, and may apply the offset to the starting physical address to determine the physical address.
