    Abstract: 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.

    Abstract: 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.

    IPC: G06F3/06

    Abstract: 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.

    IPC: H04L9/40

    CPC classification number: H04L63/0876

    Abstract: An apparatus may include a device comprising a controller configured to perform, using a first namespace identifier, a first access of a namespace of the device, wherein the device may be configured to perform, using a second namespace identifier, a second access of the namespace of the device, and wherein the second namespace identifier may include first information to determine the first namespace identifier, and second information to identify the controller. The first information may include the first namespace identifier, and the second information may include a controller identifier for the controller. The second namespace identifier may include the first namespace identifier concatenated with the controller identifier. The controller may include at least a portion of a communication endpoint. The device may further include a second controller configured to perform the second access. The first controller may include a child controller, and the second controller may include a parent controller.

    IPC: H04L9/40

    CPC classification number: H04L63/062

    Abstract: An apparatus may include a device including a first controller, and a second controller, wherein the device may be configured to receive, using the first controller, data, apply, to the data, a first protection scheme, and send, from the device, using the second controller, the data having a second protection scheme. The first protection scheme and the second protection scheme may be the same. The second controller may be configured to apply, to the data, the second protection scheme. The first protection scheme may include a first salt, and the second protection scheme may include a second salt. The first salt may be determined by the device, and the second salt may be determined by a user. The method may further include applying, at the device, to controller state information for the first controller, a third protection scheme to generate controller state information having the third protection scheme.
