Abstract

The invention provides a memory adaptive temperature control method, a memory device and a control circuit unit. The method comprises the steps that whether a first temperature value is larger than a first threshold value or not is judged; in response to determining that the first temperature value is greater than the first threshold value, executing a speed reduction operation to reduce the access speed of the memory storage device to a first speed; when the memory storage device executes data access at the first speed, judging whether the second temperature value is smaller than a second threshold value or not; in response to judging that the second temperature value is smaller than the second threshold value, calculating a first temperature change speed in a specific time range, and determining a first adjustment percentage according to the first temperature change speed; 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.

Description

technical field [0001] The present invention relates to a memory temperature control technology, in particular to a memory adaptive temperature control method, a storage device and a control circuit unit. Background technique [0002] Digital cameras, cell phones and MP3s have grown rapidly in recent years, resulting in a rapid increase in consumer demand for storage media. Because rewritable non-volatile memory has the characteristics of data non-volatile, power saving, small size, no mechanical structure, fast reading and writing speed, etc., it is most suitable for portable electronic products, such as laptop. A solid-state drive is a memory storage device that uses a flash memory module as a storage medium. Therefore, the flash memory industry has become a very popular part of the electronics industry in recent years. [0003] Memory storage devices generate a large amount of thermal energy during operation. The temperature of the memory storage device must generally...
