Abstract: Various embodiments relate to a memory controller, including: a memory interface connected to a memory; an address and command logic connected to the memory interface and a command interface, wherein the address and control logic is configured to receive a memory read request; a memory scrubber configured to cycle through memory locations and to read data from those locations; a region selector configured to determine when a memory location read by the memory scrubber is within an integrity checked memory region; a runtime integrity check (RTIC) engine connected to a read data path of the memory interface, wherein the RTIC engine is configured to calculate an integrity check value for the RTIC region using data read from the checked memory region by the memory scrubber; and a RTIC controller configured to compare the calculated integrity check value for the checked memory region to a reference integrity check value for the checked memory region.
