Original Abstract Submitted
a controller performs an access operation on a word line which is in a portion of a memory array in a memory device. the controller counts accesses on a portion-by-portion basis (e.g., a bank-by-bank basis, a sub-bank-by-sub-bank basis, etc.). the memory counts accesses on a word line-by-word line basis. the memory sets a refresh management (rfm) flag for a portion based on the counts associated with the word lines in that portion. the controller checks the rfm flag for a portion based on the access count for the portion. the controller issues an rfm command after checking the rfm flag if the rfm flag is set.
