MULTI-TIER SCHEME FOR LOGICAL STORAGE MANAGEMENT

摘要

A storage device may include a controller and a memory array including a plurality of dies arranged into a plurality of channels. In some examples, the controller may be configured to define, from the memory array, a plurality of die-sets based on respective chip enable lines associated with the plurality of dies, wherein each die-set of the plurality of die-sets includes at least one die from each of the plurality of channels; define, from a selected die-set of the plurality of die-sets, a plurality of blocksets, wherein each blockset includes a block from each die of the selected die-set; receive a unit of data to be stored; and issue commands that cause the unit of data to be stored in blocks of a selected blockset of the plurality of blocksets

1. A storage device comprising:
a memory array including a plurality of dies arranged into a plurality of channels; and a controller configured to:
define, from the memory array, a plurality of die-sets based on respective chip enable lines associated with the plurality of dies, wherein each die-set of the plurality of die-sets includes at least one die from each of the plurality of channels;define, from a selected die-set of the plurality of die-sets, a plurality of blocksets, wherein each blockset includes a block from each die of the selected die-set;receive a unit of data to be stored; andissue commands that cause the unit of data to be stored in blocks of a selected blockset of the plurality of blocksets.
