Abstract
Apparatuses and methods increased reliability row hammer counts. Each word line of a memory may have an associated count value, stored in memory cells of the word line. Information in memory cells may be prone to change, such as from neutron strike. A counter circuit may decrease the count value each time the word line is accessed, since a decreasing count will tend to overestimate accesses due to error. A count error correction circuit may check the count value against redundant information and correct the count value if there is an error. Decreasing counts and count error correction may be used together to further increase reliability.
