Abstract
Mitigating or managing an effect known as 'rowhammer' upon a DRAM device may include a memory controller receiving an activation count threshold value from the DRAM device. The memory controller may detect row activation commands directed to the DRAM device and count the number of the row activation commands. The memory controller may send a mitigative refresh command to the DRAM device based on the result of comparing the counted number of row activation commands with the received activation count threshold value.
