| 摘要 |
<p>The invention relates to a non-volatile memory device comprising:
- an input for providing external data (D) to be stored on the non-volatile memory device;
- a first non-volatile memory block (100) and a second non-volatile memory block (200), the first non-volatile memory block (100) and the second non-volatile memory block (200) being provided on a single die (10), wherein the first non-volatile memory block (100) and second non-volatile memory block (200) are of a different type such that the first non-volatile memory block (100) and the second non-volatile memory block (200) require incompatible external attack techniques in order to retrieve data there from; and
- an encryption circuit (50) for encrypting the external data (D) forming encrypted data (D', D") using unique data (K, K1, K2) from at least the first non-volatile memory block (100) as an encryption key, the encrypted data (D' , D") at least being stored into the second non-volatile memory block (200). The invention further relates to method of protecting data in a non-volatile memory device.</p> |
