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.

Abstract: A method and a memory device are provided. A controller of the memory device retrieves a first command from a host memory. The controller stores a first identifier of the first command in a set-aside buffer of the memory device. The controller retrieves a second command from the host memory. The controller initiates processing of the first command and the second command based on a second identifier of the second command corresponding to the first identifier

Abstract: A method of a buffer memory device, a storage system, and a buffer memory device are provided. The method of the buffer memory device, the buffer memory device having a lower tier memory and a higher tier memory, may include receiving a new entry request, determining that the new entry request includes an HOL entry, selecting an entry on the higher tier memory to be tiered down to the lower tier memory in response to determining that the new entry request includes an HOL entry, removing the selected entry from the higher tier memory, storing the HOL entry in the higher tier memory of the buffer memory device, and outputting the HOL entry to an arbiter.
