METHOD AND APPARATUS FOR SETTING MEMORY, AND ELECTRONIC DEVICE AND STORAGE MEDIUM

A method and apparatus for setting memory, and an electronic device and a storage medium. The method comprises: obtaining a memory application instruction generated by a process corresponding to a simulator; determining target number of times of mappings for a first virtual memory space according to the memory application instruction; determining remaining number of times of mappings of the first virtual memory space; determining whether the remaining number of times of mappings is zero; if not, mapping the first virtual memory space to a second virtual memory space by using a copy-on-write instruction, updating the remaining number of times of mappings, and returning to the step of determining whether the remaining number of times of mappings is zero; and if yes, stopping mapping the first virtual memory space to the second virtual memory space by using the copy-on-write instruction.
