Extended storage for zone metadata with user data in a memory system with a cache

A method by a memory system, comprising:

• receiving, by the memory system, a zone descriptor command comprising metadata associated with a zone of a plurality of zones of a memory array of the memory system;
• storing, to a cache of the memory system based at least in part on the zone descriptor command, one or more first entries that map the metadata to first physical addresses of a plurality of physical addresses in the cache, wherein the cache comprises one or more second entries that map data associated with the plurality of zones to respective second physical addresses of the plurality of physical addresses in the cache;
• writing the metadata to the first physical addresses in the cache based at least in part on the one or more first entries;
• and
• transferring the metadata and a subset of the data mapped by the one or more second entries from the cache to the zone in the memory array based at least in part on writing the metadata to the first physical addresses in the cache, wherein the subset of the data is associated with the zone.

A non-transitory computer-readable medium comprising code comprising instructions which, when executed by processing circuitry of an electronic device, cause the electronic device to:

• receive, by the electronic device, a zone descriptor command comprising metadata associated with a zone of a plurality of zones of a memory array of the electronic device;
• store, to a cache of the electronic device based at least in part on the zone descriptor command, one or more first entries that map the metadata to first physical addresses of a plurality of physical addresses in the cache, wherein the cache comprises one or more second entries that map data associated with the plurality of zones to respective second physical addresses of the plurality of physical addresses in the cache;
• write the metadata to the first physical addresses in the cache based at least in part on the one or more first entries;
• and
• transfer the metadata and a subset of the data mapped by the one or more second entries from the cache to the zone in the memory array based at least in part on writing the metadata to the first physical addresses in the cache, wherein the subset of the data is associated with the zone.

A memory system, comprising:

• one or more caches comprising a plurality of single-level memory cells;
• one or more memory arrays coupled with the one or more caches and comprising a plurality of multi-level memory cells, wherein the plurality of multi-level memory cells are included in a plurality of zones each comprising one or more blocks of memory cells;
• and
• processing circuitry configured to cause the memory system to:
• receive a zone descriptor command comprising metadata associated with a zone of the plurality of zones of the one or more memory arrays;
• store, to a logical-to-physical table in a cache of the one or more caches based at least in part on the zone descriptor command, one or more first logical-to-physical entries that map the metadata to first physical addresses of a plurality of physical addresses in the cache, wherein the cache is configured to store data associated with the plurality of zones;
• write the metadata to the first physical addresses in the cache based at least in part on the one or more first logical-to-physical entries;
• and
• transfer the metadata and a subset of the data from the cache to one or more multi-level memory cells in the zone in the one or more memory arrays based at least in part on writing the metadata to the first physical addresses in the cache, wherein the subset of the data is associated with the zone.

• writing the metadata to the first physical addresses in the cache based at least in part on the one or more first logical-to-physical entries;
