MEMORY ACCESS TECHNOLOGY AND COMPUTER SYSTEM

This application provides a memory access technology and a computer system. The computer system includes a memory controller, a media controller, and a non-volatile memory NVM connected to the media controller. After receiving a first read command that is sent by the memory controller, the media controller may read first data from the NVM based on a first address in the first read command. Then the media controller can return, to the memory controller, at least two fixed-length data subblocks and metadata of the at least two data subblocks based on at least two send commands sent by the memory controller. The metadata includes a location identifier that is used to indicate an offset of a corresponding data subblock in the first data. The memory controller combines the at least two data subblocks into the first data based on location identifiers in the metadata of the at least two data subblocks.
