Abstract: A system and method detect a row hammer attack on the memory media device and generates a hardware interrupt based on the detection of the row hammer attack. This row hammer interrupt is communicated to an operating system of a host computing device, which in turn performs an interrupt service routine including generating a command to perform a row hammer mitigation operation. This command is provided to the memory controller which performs the row hammer mitigation operation in response to the command such as activating victim row(s) of the memory media device or throttling data traffic to the memory media device.
