Apparatuses and methods for individualization of activation counter initialization

An apparatus comprising:

• a memory array comprising a plurality of word lines each associated with one of a plurality of access count values;
• an activation counter initialization (ACI) controller configured to provide an address count increment signal and an ACI signal during an ACI mode;
• an address counter configured to generate a row address responsive to the address count increment signal;
• a row decoder configured to activate one or more of the word lines based on the row address;
• a counter control circuit configured to set the plurality of access count values associated with the activated word lines to an ACI flag value responsive to the ACI signal;
• and
• a counter individualization circuit configured to receive an access count value of the plurality of access count values associated with an accessed word line as part of an access count update (ACU) operation and configured to initialize the access count value of the plurality of access count values to an initialization value during the ACU operation if the access count value of the accessed word line is equal to the ACI flag value.

A method comprising:

• activating a word line of a memory;
• reading an access count value along the accessed word line;
• comparing the access count value to an ACI flag value;
• initializing the access count value to an initialization value if the read access count value matches the ACI flag value.
