Memory management method and device

Abstract

The embodiment of the invention discloses a memory management method, which comprises the following steps of: receiving a memory allocation request which comprises memory size requested to be allocated; selecting a best matched memory space from all available spaces of the memory according to the memory size requested to be allocated, wherein the best matched memory space is the minimum available space in the available spaces which are no less than the memory size requested to be allocated; and responding to the memory allocation request. The embodiment of the invention also discloses a memory management device. The method and the device have the advantages of allocating the best matched available memory fragment for the memory allocation request, increasing the reusability of the memory and the request processing efficiency, maximizing the service efficiency of the memory resource, improving the processing speed of the entire system and providing better user experience.

Description

technical field [0001] The invention relates to the field of computer electronics, in particular to a memory management method and device.
