A device has a protection unit for controlling access to a memory. Indirect memory access requests have control data indicative of a memory access control register to be written to provide indirect access to a target memory and requested address data indicative of at least one memory address of the target memory to be accessed. The protection unit contains protection data defining access rights of source units to access specified address ranges of the target memory, and a system bus interface interfacing to a source unit and a memory bus interface interfacing to the target memory via a controller. The protection unit has a control monitor for detecting an indirect memory access request, and an indirect address monitor for comparing requested address data to specified address ranges and subsequently grant the indirect memory access in accordance with access rights of the respective source unit.
