Abstract
A data storage device includes a memory device and a controller coupled to the memory device. The controller is configured to store data mappings in an uLayer, where the uLayer includes a plurality of mSet updates, and where the uLayer is organized into a sorted section and an unsorted section, sort one or more of the plurality of mSet updates of the uLayer, and provide, to a host device, data stored in the memory device corresponding to a most recent update of a data mapping by ignoring non-recent updates for a read command associated with an mSet group of the sorted section.
