Abstract
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.
