Abstract
Methods, systems, and devices for extended storage for zone metadata with user data in a memory system with a cache are described. The described techniques provide for a memory system to write data and a zone descriptor extension (ZDE) for a zone to a cache before flushing the data and the ZDE to a memory array, which may support re-writable ZDE information. The cache may be addressable using a logical-to-physical (L2P) table, and entries of the L2P table that map the ZDE in the cache may be included after entries of the L2P table that map user data in the cache, and the memory system may identify the current ZDE according to the L2P table region. When the zone is closed, the memory system may flush the data to the zone of the memory array and may migrate the last written ZDE information to a fixed location within the zone.
