Abstract
A method and apparatus for implementing row hammer avoidance in a dynamic random access memory (DRAM) in a computer system. Hammer detection logic identifies a hit count of repeated activations at a specific row in the DRAM. Monitor and control logic receiving an output of the hammer detection logic compares the identified hit count with a programmable threshold value. Responsive to a specific count as determined by the programmable threshold value, the monitor and control logic captures the address where a selected row hammer avoidance action is provided.
