Standard Memory Cards for PLCs
Standard memory cards for PLCs are classified in two groups:
Saved RAM Memory Extension Cards
Saved RAM memory extension cards are typically used when generating and debugging an application program. The memory is saved by a removable battery integrated in the memory card.
Flash Eprom Memory Extension Cards
Flash Eprom memory extension cards are typically used after the process of debugging the application program is completed. Such cards allow only the global transfer of the application; their main purpose is to avoid risks often associated with battery back-ups.

Application + Files Type Memory Extension Cards
In addition to the conventional application storage area (program + constants), these memory cards also maintain a file area used by the program to archive and/or restore data.
Here are two sample applications:

File-type Memory Extension Cards without Application
These memory cards contain data. There is no application field (program + constants). These memory extension file storage cards are of the saved RAM type. The memory is saved by a removable battery built into the memory card.
