Abstract
A storage device which is connected to a host using a virtual memory includes a solid state drive that receives a streaming access command including a logical block address (LBA) list and a chunk size, and prefetches stream data requested according to the LBA list and the chunk size from a nonvolatile memory device without an additional command. The prefetched stream data is sequentially loaded onto a buffer, and an in-storage computing block accesses a streaming region registered on the virtual memory to sequentially read the stream data loaded onto the buffer in units of the chunk size. The buffer is mapped onto a virtual memory address of the streaming region.
