Description

technical field [0001] The embodiments of the present invention relate to memory technology, and in particular to a memory, a detection method thereof, and a chip integrated with the memory. Background technique [0002] In the field of information security applications, security chips based on specific cryptographic algorithms need to provide information security protection for internal sensitive information and protect the confidentiality and integrity of information. Due to the importance of its internal information, the security chip will also be attacked in various forms, and is facing serious security challenges. [0003] At present, it is a common method for hackers to crack chips by using exception injection attack means to obtain keys, and one of the effective exception injection attack means is laser fault injection attack means. The basic principle of the laser fault injection attack method to attack the chip is the internal photoelectric effect. The laser is usu...
