Abstract
Methods, systems, and devices for systems and techniques for updating logical-to-physical (L2P) mappings are described. A memory system may support improved change log entries that supports a change log entry to indicate updated L2P mapping information for multiple data chunks, thus increasing the amount of data indicated by the change log before it becomes full. One change log entry may be used to indicate updated L2P information for multiple sequential data chunks. For example, the memory system may write data to a set of contiguous data chunks of a non-volatile memory device. The memory system may write a change log entry to a change log that includes updated L2P mapping information for the set of data chunks by including at least a first indication of a virtual block that includes the data chunks and a second indication of the quantity of data chunks in the set.
