Data memory is the memory available to accommodate DBs. There are no DBs in a CPU when you get it, just empty space. You create them up to the limits of -
- maximum individual block size
- maximum number of individual blocks
- total available data memory.

The Mxxx.x memory in a CPU is already defined when it comes out of the box. Each model has a fixed address range regardless of the quantity of data memory. It can not be expanded or reduced. There is no relationship between the two. If you really need more than the number of M bits, bytes, words or double-words in the CPU you have to use one or more DBs to hold additional bits, bytes, etc
