Abstract

The invention discloses a memory management method and device. The method comprises the following steps of firstly, detecting remaining memory space of a memory of electronic equipment; and then, determining whether the residual memory space is less than or equal to a first threshold, if the residual content space is less than or equal to the first threshold, migrating part of data in the memoryto an external memory of the electronic equipment, and releasing the memory space occupied by part of data migrated to the external memory. A part of data in the memory is migrated to the external memory and the memory space occupied by the part of data is released; thus, the remaining memory space of the memory can be enlarged without forcibly ending the running application programs, so that thesituation that the kernel forcibly ends part of the programs due to the fact that the remaining memory space is too small can be avoided, and all the running programs can be kept alive.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a memory management method and device. Background technique [0002] Memory is one of the important components in electronic equipment, and all programs in electronic equipment run in memory. That is to say, when the electronic device wants to run a certain program, it first reads the relevant data corresponding to the program into the memory, and then runs the program according to the relevant data in the memory. [0003] However, the size of the memory in the electronic device is limited. For example, the size of the memory is usually only 1 gigabyte (GB) or 2GB. When the remaining memory space of the memory in the electronic device is small, the electronic device will trigger a cleaning mechanism to force End some programs running in memory (for example, programs with lower priority), and release the memory occupied by this part of programs. In this case, because...
