Systems and methods for fast execution of in-capsule commands are disclosed. NVM Express (NVMe) over fabrics is a standard in which a host device sends commands in a command capsule to a memory device. The memory device then saves the command capsule as an entry to a submission queue, and thereafter fetches the command capsule from the submission queue for execution. In certain instances, such as when the command capsule includes a write command, the memory device may decide to by-pass the submission queue and instead begin execution of the command without fetching the command from the submission queue. In these instances of bypassing, the memory device may instead insert a no-operation entry in the submission queue. Further, the memory device may send a response capsule prior to beginning execution of the command.
