    摘要： A storage device may include at least one storage medium and a controller configured to receive a write command, wherein the write command specifies data and a reclaim unit handle, receive information about the data, and store, based on the reclaim unit handle and the information, the data in a reclaim unit of the at least one storage medium. The information may include access information. The information may include error tolerance information. The information may include data attribute information. The information may include data type information. The controller may be configured to determine the information based, at least in part, on the reclaim unit handle. The controller may be configured to receive an indicator that may be separate from the reclaim unit handle, and determine the information based, at least in part, on the indicator.

    摘要： A storage device may include at least one storage medium, and a controller that may include at least one processor configured to perform an update operation associated with a reclaim unit handle that references at least one reclaim unit of the at least one storage medium, read, based on the update operation, data from a first reclaim unit of the at least one storage medium, and write, based on the update operation, the data to a second reclaim unit of the at least one storage medium. Based on the update operation, the second reclaim unit may be associated with the reclaim unit handle. The first reclaim unit may be associated with the reclaim unit handle. The reclaim unit handle may be a first reclaim unit handle, and the first reclaim unit may be associated with a second reclaim unit handle.

    摘要： An apparatus may include a storage device that may include at least one storage medium and a controller configured to control the at least one storage medium, wherein the controller may be configured to: receive a write command, wherein the write command may indicate a reclaim unit handle; perform, based on the reclaim unit handle, and based on an operation or condition of the storage device, a selection of a reclaim unit of the at least one storage medium; and store, based on the write command, data to the reclaim unit. The storage medium may include a first reclaim group including the first reclaim unit and a second reclaim group including a second reclaim unit of the at least one storage medium, and the selection of the first reclaim unit may include performing a selection of the first reclaim group.

    摘要： A method may include receiving, at a device, a copy command, wherein the copy command comprises a first indication of a first amount of source data and a second indication of a second amount of source data, determining, based at least in part on the first indication, an amount of destination space, and blocking at least a portion of the amount of destination space. The method may further include reading the first indication, and reading the second indication, wherein the amount of destination space may include at least a first portion of the first amount and at least a second portion of the second amount. The blocking may include blocking the at least the first portion of the first amount and the at least the second portion of the second amount. The method may further include storing the first indication to generate a stored first indication.

    摘要： A method and a memory device are provided. A controller of the memory device retrieves a first command burst from a host memory. The first command burst includes a sequence of one or more commands from a first submission queue. The controller identifies that at least one command in the first command burst is at least one first fused command of a first set of fused commands. The first set of fused commands is to be processed atomically in the memory device, and a remainder of the first set of fused commands is on the first submission queue. The controller stores at least an identifier of the at least one first fused command in a set-aside buffer of the memory device.
