Abstract

See full text

A data storage device includes a memory device and a controller coupled to the memory device. The controller is configured to allocate two or more zones to a first superblock of a plurality of superblocks. The controller is further configured to allocate a zone to a second superblock, where the second superblock only stores data of the zone. The first superblock has a first priority and the second superblock has a second priority, where the second priority is greater than the first priority. Data is moved from the first superblock to another superblock dedicated for a single zone after the first superblock is closed.
