Sorry, I can't remember and don't have the manual for the 3UB11. But here's a faximile from the 3UB21 manual. I interpret it as the RAM is built-in. But the online info from the CPU will tell how the memory is arranged.
EDIT:
Here's from another manual (6ES5998-0SH21) . Still not the same MLFB, but inicating you're right, Moggie.
"You require a user memory submodule (RAM or EPROM) for storage of your
program. You can store up to 64 x 210 bytes of code and data blocks here. For
data blocks, the CPU 928 additionally has an integrated DB RAM of
46 x 210 bytes."

Dear Kalle thanks for your reply,
Can i upload S5 program directly to any EPROM or EEPROM from Step5 Software? without Siemens Prommer.
