Abstract
Apparatuses, systems, and methods for main sketch and slim sketch circuits for address tracking. The main sketch circuit receives a row address and changes selected count values in a first storage structure based on hash values generated based on the row address. Those count values are compared to a first threshold, and if that threshold is exceeded, a slim sketch circuit also receives the row address and changes selected count values in a second storage structure based on hash values generated based on the row address. Based on the selected count values from the first storage structure, the second storage structure, or combinations thereof, the row address may be determined to be an aggressor address.
