Abstract
A method of performing memory operations of a memory device having precharge, read and write states is disclosed. The method includes refreshing the memory device provided a refresh timer expired and the memory device is in the precharge state. The method further includes entering the precharge state, refreshing the memory device and returning to the read state provided the memory device is in the read state for a predetermined period of time. The memory device is refreshed provided the memory device is transitioning from the read state to the write state and the refresh timer has expired.
