AN ELECTRONIC DEVICE HAVING A MEMORY ELEMENT AND METHOD OF OPERATION THEREFOR

摘要

An electronic device (200) comprises a processing unit (220) operably coupled to a buffer random access memory (RAM) (215), in turn operably coupled to a non-volatile memory (205) configured to emulate an electrically erasable programmable read only memory (EEPROM). The processing unit (220) is arranged to transfer data between the buffer RAM (215) and the non- volatile memory (205) at a first clock frequency. A second RAM (225) is operably coupled between the processing unit (220) and the non-volatile memory (205) and the processing unit (220) sets a Tag bit in the second RAM (225) to identify an address in the buffer RAM (215) that is being written to or read from by the processing unit (220).
