Row hammer correction logic for dram with integrated processor

A method for protecting a memory device from the Row Hammer effect, the memory device comprising one or more bank(s), each bank comprising a plurality of DRAM memory rows, the method comprising the steps of:

• monitoring, using a detection logic triggering of the Row Hammer and for each bank, row activation commands emitted by the external memory controller and/or by one or more internal processor(s) of the memory device, each row activation command causing the row of said bank to be activated before being accessed by the external memory controller or by one or more internal processor(s);
• storing, using the detection logic triggering of the Row Hammer, one or more table(s) indicating for each row of a subset of rows of each bank, a count value based on the number of activation commands for the row, wherein the subset of rows associated with a count value in one or more table(s) is dynamically modified by the detection logic triggering of the Row Hammer based on the count values, to indicate the most frequently activated rows based on the detection of activation commands for each row of each bank;
• storing, using the detection logic triggering of the Row Hammer, an additional count value indicating the maximum number of activation commands that could have been aimed at any row not belonging to said sub-sets of rows;
• comparing, using the detection logic triggering of the Row Hammer, each of the count values with a threshold level in order to identify one or more row(s) in one or more table(s);
• triggering, using the detection logic triggering of the Row Hammer, an operation to refresh one or more row(s) adjacent to the identified row;
• and
• implementing, using a logic for sending preventive refresh, the refresh operation for one or more adjacent row(s) of each identified row by emitting refresh requests instead of the periodic refresh requests generated by the external memory controller, thereby delaying one or more of said periodic refresh requests.
