Abstract: A method of operating a storage device for reducing write latency. The storage device determines whether to support write data support (WDS), fetches a write command selectively including an instant write flag when WDS is supported, updates an address mapping table regarding a controller memory buffer (CMB) without an host direct memory access (HDMA) operation in response to the fetched write command, and generates write command completion message corresponding to the write command.
