Abstract
A memory apparatus and an operating method thereof are provided. The memory apparatus includes a memory, a temperature sensor and a control circuit. The temperature sensor senses a temperature of the memory and generating a temperature sensing signal. The control circuit is coupled to the memory and the temperature sensor. The control circuit performs access operation on the memory and changes a frequency of the access operation with reference of a delay curve according to the temperature sensing signal.
Claims8
A memory apparatus, comprising:
- a memory;
- a temperature sensor, sensing a temperature of the memory and generating a temperature sensing signal;
- and
- a control circuit, coupled to the memory and the temperature sensor, performing access operation on the memory, and changing a frequency of the access operation with reference of a hysteresis curve according to the temperature sensing signal,
- wherein the control circuit decreases the frequency of the access operation when the temperature of the memory changing from a temperature above a first threshold to a temperature below the first threshold and increases the frequency of the access operation when the temperature of the memory changing from a temperature below a second threshold to a temperature above the second threshold, wherein the first threshold is smaller than the second threshold.
