No, this version of CPU only accepts FEPROM. Even physically MMC and FEPROM totally different including the size and shape
In your version of CPUs if there is no FEPROM, then program is retained only by the battery.
The CPU 6ES7 313-1AD03-0AB0 has two integrated memeory area. Check the links below for some info. http://support.automation.siemens.com/WW/view/en/7302326 Check attachment 01 in that FAQ for some more info. In your version of CPUs if there is no FEPROM, then program is retained only by the battery. Here is the memory spec of you CPU
In Simatic Manager, if you right click on the folder "Blocks" and goto properties, it will show how much load and work memory is required by the program. If this is not a problem but still you are facing memory shortage, try compressing the memory. (What this does isvery similar to de-fragment of Hard disk.) There is no way to expandwork memory as you can see in the table. |

Check chapter 19 of the manual below for everthing about memory and download options http://support.automation.siemens.com/WW/view/en/18652056 |

The question is whether i can (for the specific CPU) save in the FEPROM only the work memory, and not the load memory as well. The work memory of my program fits the FEPROM (16kB). The problem is when it tries to copy the load memory as well to FEPROM. Then the flash memory is not enough. Can i select which memory to copy anywhere? |

No, loadmemoryisobligatory. |

I amuploading the properties of my program's Blocks. Is there a way to reduce the load memory data, in order to be able to copy RAM in a ROM of 16kB? I had in mind something like getting rid of some elements of the load memory, because i think that since the work memory of CPU 313 is 16kB, the choice of a 16kB FEPROM maybe a reasonable one. |

You can try to re-structurize your project to reduce total amout of data (for example by adding some FCs and FBs) - but i think you won't get much. Guess best way for you is simply buying FEPROM of larger size.... I'm not sure, but maybe FEPROMs for S7-400 would fit. |
