Abstract
The method uses an integrated circuit comprising a processor (603), a non-volatile memory (602), especially a flash memory, a system clock and an interface (605), which is connected on the one side to the processor (602) and on the other side to the non-volatile memory (602). When the address (ba[ ]) provided by the processor (603) has changed, the interface (605) leads the address (ba[ ]) to the non-volatile memory (602), 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 (602). As soon as the data in the non-volatile memory (602) corresponding to the address (ba[ ]) are available the data will be directed to the processor (603). Thereby it is possible to get on the integrated circuit the highest data throughput according to the flash memory (602) access time and a minimized chip area at the same time.
