Abstract
A method is provided to access a data storage memory that stores data signals in a plurality of indexed memory locations. An access control circuit receives a memory access request signals from a processing circuit. The method includes replicating the respective memory access request signals to provide for each a respective replicated memory access request signal, accessing indexed internal memory locations to retrieve a first data signal retrieved as a function of the respective memory access request signal and a second data signal retrieved as a function of the respective replicated memory access request signal, and checking for identity the first data signal and the at least one second data signal. The access control circuit transmits to the processing circuit a data signal or an integrity error flag signal as a result of the identity check.
