摘要： 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.

摘要： A memory access method, a storage-class memory, and a computer system are provided. The computer system includes a memory controller and a hybrid memory, and the hybrid memory includes a dynamic random access memory (DRAM) and a storage-class memory (SCM). The memory controller sends a first access instruction to the DRAM and the SCM. When determining that a first memory cell set that is of the DRAM and to which a first address in the received first access instruction points includes a memory cell whose retention time is shorter than a refresh cycle of the DRAM, the SCM may obtain a second address having a mapping relationship with the first address. Further, the SCM converts, according to the second address, the first access instruction into a second access instruction for accessing the SCM, to implement access to the SCM.

摘要： An electronic device includes a processor, a volatile memory, and a non-volatile memory. The non-volatile memory stores a first operating system, and the electronic device works in a first working mode and a second working mode. When the electronic device is in the first working mode, a second operating system is run in the volatile memory. When the processor detects that the electronic device reaches a preset condition for entering the second working mode, the non-volatile memory is enabled, and non-system data in the volatile memory is moved to the non-volatile memory. The non-system data does not include the second operating system. After the movement of the non-system data is completed, the volatile memory is disabled, and the first operating system is run in the non-volatile memory, so that the electronic device enters the second working mode.

摘要： An information storage apparatus includes a magnetic track, a writer, and a reader, where the magnetic track includes a number of magnetic domains. Each magnetic domain is divided into at least two magnetic regions, and the writer is disposed on the magnetic track, and configured to write information to the at least two magnetic regions of each magnetic domain. The reader, disposed on the magnetic track, is configured to read the written information from the at least two magnetic regions. Therefore, multiple pieces of valid information are written to one magnetic domain of the magnetic track, thereby increasing storage density of the magnetic track, and expanding a storage capacity of the storage apparatus.

摘要： A magnetic storage track and a magnetic memory are provided. The magnetic storage track includes multiple stacked storage track units. A transition layer is disposed between two neighboring storage track units. The transition layer is constituted by a semiconductor material deposited on an insulating material, and includes a gating circuit and a read/write apparatus. Because the magnetic storage track includes multiple stacked storage track units, a track length of the magnetic storage track is constituted by track lengths of the multiple storage track units. Therefore, when a storage capability of the magnetic storage track needs to be improved, the track length of the magnetic storage track may be increased by adding the storage track unit.
