Methods, systems, and devices for memory operations are described. A first set of commands may be received for accessing a memory device. The first set of commands may include non-consecutive logical addresses that correspond to consecutively indexed physical addresses. A determination that the non-consecutive logical addresses correspond to consecutively indexed physical addresses may be determined based on a first mapping stored in a volatile memory. A second mapping may be transferred to the volatile memory based on the determination. The second mapping may include an indication of whether information stored at a set of physical address is valid. A second set of commands including non-consecutive logical addresses may be received for accessing the memory device. Data for the second set of commands that include the non-consecutive logical addresses may be retrieved from the memory device using the second mapping.
