ABSTRACT:
A memory device has refresh cycles to refresh memory cells of the memory device. The time interval between one refresh cycle to the next refresh cycle is a refresh interval. The refresh interval depends on a frequency of an oscillating signal. A refresh timer adjusts the frequency of the oscillating signal based on changes in the temperature to adjust the refresh interval.
