Classification: CPC G  Y | IPC G

Claim 0:
1. A memory adaptive temperature controlling method for a memory storage device comprising a memory control circuit unit and a rewritable non-volatile memory module, wherein the memory control circuit unit is configured to control the rewritable non-volatile memory module, and the method comprises:
measuring a temperature through a thermal sensor to obtain a first temperature value, and determining whether the first temperature value is greater than a first threshold value;
in response to determining that the first temperature value is greater than the first threshold value, performing a speed-down operation to reduce an access speed of the memory storage device to a first speed;
when the memory storage device performs data is accessed at the first speed, measuring the temperature through the thermal sensor to obtain a second temperature value, and determining whether the second temperature value is less than a second threshold value;
determining that the second temperature value being less than the second threshold value;
in response to determining that the second temperature value is less than the second threshold value, calculating a first temperature change rate within a specific time range, and determining a first adjustment percentage according to the first temperature change rate; and
calculating a second speed according to the first speed and the first adjustment percentage, and adjusting the access speed of the memory storage device to the second speed.
