Abstract:
A method for performing a refresh operation based on system characteristics is provided. A The method includes determining that a current operation condition of a memory component is in a first state and detecting a change in the operation condition from the first state to a second state. The method further includes determining a range of the operation condition to which the second state belongs. The method further includes determining a refresh period associated with the range of the operation condition, the refresh period corresponding to a period of time between a first time when a write operation is performed on a segment of the memory component and a second time when a refresh operation is to be performed on the segment. The method further includes performing the refresh operation on the memory component according to the refresh period.
