Methods of operating multi-zone memory systems, memory systems, hosts and memory controllers

Abstract

An example method includes obtaining a first zone mapping table, wherein the first zone mapping table includes first write pointers for multiple zones, the multiple zones are obtained by dividing a logical address space corresponding to a non-volatile storage device, and a first write pointer indicates a predicted next writable LBA in a zone; obtaining a second zone mapping table, wherein the second zone mapping table includes second write pointers for the multiple zones, and a second write pointer indicates a next writable LBA in a zone; and determining a zone in the multiple zones, for which the first write pointer and the second write pointer are different, to be a dirty zone based on the first zone mapping table and the second zone mapping table.
