Abstract

The embodiment of the application discloses a memory allocation method and device and electronic equipment. The method comprises the steps of responding to an instruction for distributing memory to an application program, obtaining memory demand corresponding to the instruction, and obtaining memory configuration from the rest of memory to the application program if the rest of memory in a pre-configured first memory area meets the memory demand, wherein addresses of the memory included in the first memory area are continuous. Therefore, under the condition that the first memory area with continuous addresses is preconfigured, and under the condition that the memory is required to be allocated for the application program, the memory allocation degree can be directly selected from the first memory area, so that the required memory can be allocated for the application program more quickly by utilizing the characteristic that the addresses of the memories in the first memory area are continuous.
