Claim 3:
4. A memory system, comprising:
one or more memory devices; and
processing circuitry coupled with the one or more memory devices and configured to cause the memory system to:
receive a command associated with data having a corresponding set of logical addresses;
determine whether a subset of logical addresses of the set of logical addresses is sequential;
generate a set of entries based at least in part on the determining, each entry of the set of entries indicating a mapping between a logical address of the set of logical addresses and a physical address of a set of physical addresses, the set of entries associated with a first level of a mapping information;
store an entry in a second level of the mapping information based at least in part on the generating, the entry indicating the mapping between the set of logical addresses and the set of physical addresses based at least in part on the subset of logical addresses being sequential;
determine whether a second subset of logical addresses is sequential;
generate a second set of entries associated with the first level of the mapping information based at least in part on the determining, each entry of the second set of entries indicating a second mapping between a logical address of the second subset of logical addresses and a physical address of a second set of physical addresses;
update the entry in the second level of the mapping information based at least in part on the generating, the updated entry comprising an exception pointer indicating the second mapping between the subset of logical addresses and the second set of physical addresses based at least in part on the second subset of logical addresses not being sequential;
determine whether a quantity of exception pointers in the updated entry satisfies a threshold; and
discard the updated entry in the second level of the mapping information based at least in part on the quantity of exception pointers satisfying the threshold.
