Abstract
A method of operating a volatile memory device includes storing address information of weak cell rows. According to some examples, after writing to a weak cell row, a refresh operation is performed on the weak cell row within a predetermined time. According to some examples, the writing operation to a weak cell row may be performed with a longer write recovery time than a write recovery time to normal cell rows.
