Embodiment Construction

[0008] For a more detailed understanding of the features and technical content of the present invention, please refer to the following description and accompanying drawings. However, the accompanying drawings are for reference only and are not intended to limit the present invention.

[0009] figure 1 Shown is a system embodiment of the present invention, the protection system 100 includes a temperature sensor 101 and a threshold trigger 102 , and the static memory working device 105 includes a CPU 103 and a static memory 104 . The temperature sensor 101 is placed near the static memory 104, and when the measured temperature reaches the set threshold value, the threshold trigger 102 will trigger the CPU 103 of the static memory working device to execute the static memory deletion program.

[0010] The temperature sensor 101 can use any suitable temperature sensor (such as thermistor, thermocouple) and circuit structure (analog circuit, analog / digital circuit).

Abstract

The invention relates to a protective device for preventing a static memory from being broken by a low temperature. The system includes a static memory work device and a protective system, and the related protective system comprises a temperature sensor and a threshold trigger. The temperature sensor is placed near the static memory, and when a measured temperature reaches a set threshold value, the threshold trigger triggers the static memory work device to perform a static memory delete program.

Description

technical field [0001] The invention relates to storage device protection technology, in particular to a protection device for static memory from low-temperature cracking. Background technique [0002] In many fields such as financial electronics, government and military departments, storage devices are required to store confidential information, which can only be used by the owner himself or authorized persons. However, this kind of storage device is often in an unsafe application environment, and the stored information is easy to be stolen and leaked. Therefore, it is of great significance to protect the security of confidential storage devices. [0003] In order to protect the confidential information from being leaked, it is necessary to make the confidential information disappear after the storage device is lost and before the confidential information is stolen. At present, the commonly used schemes to protect confidential information when under attack are carried out...
