Abstract: A method and a device for clearing a process in an electronic device are provided. The method includes calculating an amount of memory allocated for a preset time period when a memory application is requested, predicting an amount of memory to be allocated for a future setting time period based on the amount of the memory, and selecting and clearing at least one of present processes based on the amount of the memory to be allocated. Accordingly, sufficient memory can be obtained in a short period of time by recalling a plurality of processes. In this way, the electronic device can continuously allocate an abundance of memory.
