Abstract: Embodiments of the disclosure provide an apparatus for adding a protection function for an indirect access memory controller. The apparatus can include: a bus monitoring unit configured to monitor a bus address, perform permission authentication if a register controlling operation is detected, and configure a list entry if a permission list configuring operation is detected; an permission list unit configured to partition a memory space into several virtual memory protection areas and independently set an access permission attribute (i.e.: readable, writable, erasable, etc.) of each memory area; a window register information bus configured to provide window register information, i.e.
