The method uses an integrated circuit comprising a processor (), a non-volatile memory (), especially a flash memory, a system clock and an interface (), which is connected on the one side to the processor () and on the other side to the non-volatile memory (). When the address (ba[ ]) provided by the processor () has changed, the interface () leads the address (ba[ ]) to the non-volatile memory (), creates a strobe signal (CL; DCR) within the system clock cycle during which the address (ba[ ]) has changed and directs it to the non-volatile memory (). As soon as the data in the non-volatile memory () corresponding to the address (ba[ ]) are available the data will be directed to the processor (). Thereby it is possible to get on the integrated circuit the highest data throughput according to the flash memory () access time and a minimized chip area at the same time.

Method for fetching data from a non-volatile memory in an integrated circuit and corresponding integrated circuit

The integrated circuit according to the invention comprises a processor (), a non-volatile memory () and an interface (), where said interface () contains a first cache memory () and a second cache memory () and connects the processor () to the non-volatile memory (). The interface () gets data from the non-volatile memory () and stores them in said first or said second cache memory () intermediately and provides the processor () with data from said first cache memory () or from said second cache memory (), depending on where the requested data are stored.
