Dual cache architecture and logical-to-physical mapping for a zoned random write area feature on zone namespace memory devices

A non-transitory computer-readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to:

• allocate random write resources to a first portion of a zone having a range of logical block addresses (LBAs) and a first cache storing data of the first portion of the zone;
• receive a first write command including a first LBA;
• map the first LBA to a first physical block address (PBA) of the first cache using a first logical to physical mapping (L2P) table, wherein each of one or more LBAs in the range of LBAs of the first portion of the zone is mapped to a corresponding PBA of the first cache using one or more entries of the first L2P table and wherein a range of sequential LBAs of a second portion of the zone is mapped to a physical block of the zone, each LBA of the range of sequential LBAs accessed using an offset corresponding to a position of each LBA in the range of sequential LBAs of the second portion of the zone;
• and
• execute the first write command at the first PBA.

A system comprising:

• a plurality of memory devices;
• and
• a processing device, operatively coupled with the plurality of memory devices, to:
• allocate random write resources to a first portion of a zone having a range of logical block addresses (LBAs) and a first cache storing data of the first portion of the zone;
• receive a first write command including a first LBA, wherein the first LBA is included in the range of LBAs of the first portion of the zone;
• map the first LBA to a first physical block address (PBA) of the first cache using a first logical to physical mapping (L2P) table, wherein each of one or more LBAs in the range of LBAs of the first portion of the zone is mapped to a corresponding PBA of the first cache using one or more entries of the first L2P table and wherein a range of sequential LBAs of a second portion of the zone is mapped to a physical block of the zone, each LBA of the range of sequential LBAs accessed using an offset corresponding to a position of each LBA in the range of sequential LBAs of the second portion of the zone;
• and
• execute the first write command at the first PBA.
