Abstract
A system includes integrated circuit (IC) dies having memory cells and a processing device coupled to the IC dies. The processing device performs operations including storing, within a zone map data structure, zones of a logical block address (LBA) space sequentially mapped to physical address space of the IC dies. A zone map entry in the zone map data structure corresponds to a data group written to one or more of the IC dies. The operations further include storing, within a block set data structure indexed by a block set identifier of the zone map entry, a die identifier and a block identifier for each data block of multiple data blocks of the data group, and writing multiple data groups, which are sequentially mapped across the zones, sequentially across the IC dies. Each data block can correspond to a media (or erase) block of the IC dies.
