摘要: An automatic memory space switching method including the step of enabling a CPU of an electronic apparatus to run a BIOS of a ROM when started, the step of enabling the ROM to provide a control signal to the CPU, causing it to detect an updated version of software program in memory ICs, the step of enabling the CPU to control a switch controller and a common selector in switching a CSROM thereof to the memory IC which is stored with the updated version of software program when the CPU detects the existence of an updated version of software program in one memory IC, the step of enabling the CPU to run the detected updated version of software program and then to continuously run a posterior software program stored in the ROM, and the step of enabling the CPU to run the software program stored in the ROM without making a switching operation when the CPU detects no updated version of software program in the memory ICs.
