The first non-volatile memory stores first encrypted data encrypted with a global key. The application circuit includes a second non-volatile memory, a decryption unit, a local key unit, and an encryption unit. The second non-volatile memory stores the global key. The decryption unit is coupled to the first non-volatile memory and the second non-volatile memory. The decryption unit retrieves the global key from the second non-volatile memory and decrypts the first encrypted data with the global key to generate plain data. The local key unit generates or stores a local key. The encryption unit is coupled to the local key unit. The encryption unit encrypts the plain data with the local key to generate second encrypted data and overwrites the first encrypted data in the first non-volatile memory with the second encrypted data."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Electronic device capable of protecting confidential data","description":"An electronic device includes a first non-volatile memory and an application circuit.
