Abstract
An operating method of a memory device includes the following operations: detecting a first temperature of the memory device; determining a first refresh rate according to the first temperature; and refreshing the memory array by the first refresh rate. The first refresh rate is lower than a refresh rate upper threshold.
Claims10
An operating method of a memory device, comprising:
- detecting a first temperature of the memory device;
- determining a first refresh rate according to the first temperature;
- refreshing the memory device by the first refresh rate, wherein the first refresh rate is lower than a refresh rate upper threshold determined by a Joint Electron Device Engineering Council (JEDEC) spec;
- and
- determining a second refresh rate according to a second temperature, wherein the second temperature is higher than the first temperature, and the second refresh rate is higher than the first refresh rate, and the second refresh rate is lower than the refresh rate upper threshold.

A memory device, comprising:
- a temperature sensor, configured to detect a first temperature of the memory device;
- a memory array;
- and
- a controller, configured to determine a first refresh rate according to the first temperature and to refresh the memory array by the first refresh rate, wherein the first refresh rate is lower than a refresh rate upper threshold determined by a Joint Electron Device Engineering Council (JEDEC) spec,
- wherein the controller is further configured to determine a second refresh rate according to a second temperature, wherein the second temperature is higher than the first temperature, the second refresh rate is higher than the first refresh rate, and the second refresh rate is lower than the refresh rate upper threshold.
