If in doubt RTFM

Code - Executable Instructions RO-Data - Read Only, Constant data/arrays RW-Data - Read Write, Variables in RAM with values ZI-Data - Zero Initialize, Variables in RAM which are zero/cleared The FLASH foot print is the combination/sum of Code+RO+RW, the RW data is there because the startup/run-time has to copy it from fixed ROM into uninitialized RAM, the zero memory is just described and cleared by the same code. The RAM foot print is RW+ZI

What is RTFM?

Read The Field Manual, Read The Fine Manual, ... Beyond its early adoption by military personnel, electronic engineers and technicians, the principle of “helping oneself to knowledge� became more commonplace in other occupation fields, most notably in programming and customer support. I'm sure the question is covered in the documentation, and has been asked/answered multiple times on the interwebs.
