Abstract
A storage device may include a data storage portion, including a plurality of blocks of data, and a controller. The controller may be configured to receive a command that includes an inherent trim request for the plurality of blocks of data. The controller may be configured to perform a trim operation on a first set of trim blocks from the plurality of blocks of data, which may include fewer than all blocks of the plurality of blocks of data and may include trim blocks on which the controller can complete the trim operation within a predetermined time. The controller may be configured to update a pending trim table to include an indication of a second set of trim blocks on which trim is to be performed, which may include blocks of data on which the controller cannot complete the trim operation within the predetermined time.
