A controller of a memory may include an aggressor detector circuit which determines if addresses are aggressor addresses or not. The controller may include a tracker circuit which may count a number of times an address is identified as an aggressor, and may determine if the aggressor address is a frequent aggressor address based on the count. If the address is a frequent aggressor address, a cache entry associated with the frequent aggressor address may be locked (e.g., for a set amount of time). In some embodiments, the controller may include a second tracker which may determine if the frequent aggressor address is a highly attacked address. An address mapping associated with the highly attacked address may be changed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatuses and methods for row hammer based cache lockdown","description":"Apparatuses, systems, and methods for row hammer based cache lockdown.
