Abstract: The problem to be solved is to seek an alternative to known addressing methods which provides the same or similar effects or is more secure. Solution The problem is solved by a method (40) of addressing memory in a data-processing apparatus (10) comprising, when a central processing unit (11), while performing a task (31, 32, 33, 34) of the apparatus (10), executes an instruction involving a pointer (59) into a segment (s, r, d, h, f, o, i, c) of the memory: decoding the instruction by means of an instruction decoder (12), generating a virtual address (45) within the memory by means of a safe pointer operator (41) operating on the pointer (59), augmenting the virtual address (45) by an identifier (43) of the task (31, 32, 33, 34) and an identifier (44) of the segment (s, r, d, h, f, o, i, c), said identifiers (43, 44) being hardware-controlled (42), and, based on the augmented address (45), dereferencing the pointer (59) via a memory management unit (13).
