Abstract: The present invention provides a method for managing dynamic memory between a host operating system and a guest operating system in an electronic device for executing a multi-operating system. A method for managing dynamic memory enables, with respect to the available memory state of a host operating system and a guest operating system, direct determination of transmission of guest operating system memory to the host operating system by the guest operating system and recovery of the transmitted memory to the guest operating system and enables a request for execution to the host operating system. Moreover, with respect to memory availability state information of the guest operating system, memory information of the host operating system can be collected at a designated collecting interval by means of a request to the host operating system. Also, the host operating system can allocate dynamic memory of the guest operating system with respect to a request from the guest operating system.
