Abstract: A data operating method, device, and system are provided and relate to the computer field, so as to resolve a prior-art problem of low efficiency of performing a data operation on a block device by a CPU. The method includes: receiving an operation instruction sent by a CPU; when the operation instruction is a read instruction, reading a first data block in the block device and returning to-be-read data in the first data block to the CPU; or when the operation instruction is a write instruction, writing, into a cache, to-be-written data indicated by the write instruction, and writing, into the block device, a second data block that includes the to-be-written data. The method is used to operate data in a block device.

Abstract: A memory reclamation method and apparatus are disclosed. The memory reclamation method is performed by a processor for reclaiming memory pages of a non-volatile memory (NVM) in a terminal device. In the method, the processor receives a memory reclamation request message including a reclamation identifier which is used to indicate a quantity of memory pages requested to be reclaimed. Then, the processor reclaims inactive memory pages of the NVM according to the reclamation identifier in ascending order of the write times of inactive memory pages of the NVM. According to the memory reclamation method, a page having a relatively small quantity of inactive memory page write times of the NVM is reclaimed first, and a page having a relatively large quantity of inactive memory page write times of the NVM is reclaimed later.
