Abstract
A storage subsystem comprises a set of zone definitions that uses physical block addresses to divide a memory array in the storage subsystem into zones or segments. A set of zone parameters defines user access modes and security levels for each of the segments. Defining zones for the memory array provide flexibility and increased protection for data stored in the memory array. For example, data of one zone can be quickly erased without affecting data stored in other zones and critical data can be stored in read-only zones to prevent inadvertent overwrite.
