    Abstract: A memory allocation method and a device, where the method is applied to a computer system including a processor and a memory, and comprises, after receiving a memory access request carrying a to-be-accessed virtual address and determining that no memory page has been allocated to the virtual address, the processor selecting a target rank group from at least two rank groups of the memory based on access traffic of the rank groups. The processor selects, from idle memory pages, a to-be-allocated memory page for the virtual address, where information about a first preset location in a physical address of the to-be-allocated memory page is the same as first portions of address information in addresses of ranks in the target rank group.

    Abstract: A memory access technology and a computer system, where the computer system includes a memory controller, a media controller, and a non-volatile memory (NVM) coupled to the media controller. After receiving a first read command from 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 transmit, to the memory controller, at least two fixed-length data subblocks and metadata of the at least two data subblocks in response to at least two first send commands received from the memory controller. The metadata includes a location identifier indicating an offset of a corresponding data subblock in the first data. Thus, the memory controller obtains the first data based on the at least two data subblocks and location identifiers in the metadata.

    Abstract: A hybrid storage device includes a controller, a volatile storage unit, and a non-volatile storage unit. When the hybrid storage device is in a first working mode, the volatile storage unit is in an enabled state, and the non-volatile storage unit is in a disabled state; when the hybrid storage device is in a second working mode, the non-volatile storage unit is in an enabled state, and the volatile storage unit is in a disabled state. When the hybrid storage device runs in the first working mode, and when detecting that a running parameter of the computer meets a first switching condition, the controller enables the non-volatile storage unit, copies data in the volatile storage unit to the non-volatile storage unit, and switches the hybrid storage device to the second working mode.
