Abstract:
1. A non-volatile memory device comprising: an input port for providing external data to be stored on the non-volatile memory device; a first non-volatile memory circuit and a second non-volatile memory circuit, the first non-volatile memory circuit and the second non-volatile memory circuit being provided on a single die and are layout-wise interlaced, wherein the first non-volatile memory circuit and second non-volatile memory circuit are of a different type such that the first non-volatile memory circuit and the second non-volatile memory circuit require incompatible external attack techniques in order to retrieve data there from; and an encryption circuit for encrypting the external data forming encrypted data using unique data from at least the first non-volatile memory circuit as an encryption key, the encrypted data at least being stored into the second non-volatile memory circuit.
