Abstract: A computational storage device includes a non-volatile memory (NVM) device; and a storage controller configured to control the NVM device. The storage controller includes: a computation processor configured to execute an internal application to generate an internal command; a host interface circuit configured to receive a host command from an external host device, to receive the internal command from the computation processor, and to individually process the received host command and the received internal command; a flash translation layer (FTL) configured to perform an address mapping operation based on a result of the processing of the host interface circuit; and a memory interface circuit configured to control the NVM device based on the address mapping operation of the FTL.
