Anmbiguous. Could mean:

it's quite common in bigger embedded systems to copy the program into
RAM at boot time, and run it from there. Of course, PCs etc. always run
out of RAM.

"Running out of ROM" means "Running in RAM" (?)
Does "Running out of RAM" mean "Running in ROM"?

No, "running out" means there is not enough left. So running out of ROM
means your code does not fit in ROM anymore. Running out of RAM means all
your variables do not fit in RAM anymore.

No. I am afraid you have a double problem of
-) insufficient mastery of English language
-) little acquaintance with (micro) computer hardware terminology
as already said: "running out of" means "developing a shortage of"
ROM stands for Read-only-memory, it is
where your executable code get stored
RAM is a rather unlucky term describing read/write memory,
this is the place where your variables and stack exist.
Allow me to suggest you find some basic introduction
to microcontrollers, in English language,
and work your way through.
Specific questions can always be posted here
But I am afraid your present question indicates
that you have a long way to go.
Excuse me for being straightforward...
Good luck anyway!

No, the other way round. In this usage (i.e. indicating where the
program codes resides), Running out of RAM means running IN RAM!
And, of course, running out of ROM means running in ROM.
Sorry, it's a queer language, this English. Left is right, right is
wrong, no means yes (sometimes).

And it can also mean "running residing in" or "running from".
As in: The code on my last ARM project was running out of RAM,
but the code in my H8/300 project runs from ROM.

You are right! Much depends on context.
As someone else implied: perhaps English is not the
perfect language for scientifical/technical conversations... |

Aren't we mixing up "running out of RAM" with "executing in RAM"?

It's not at all uncommon for "running out of RAM" to mean
"executing in RAM". And if you write too much code you'll be
"running out of RAM" in both senses.

No, either meaning is a possibility. Usually the context would help
disambiguate.*
See, for example, this message:
http://sources.redhat.com/ml/ecos-discuss/2003-04/msg00611.html
"Notice that gdb continuously modifies running code in order to insert
breakpoints etc. (this is true with bdm and serial connections) If you
want to debug, code should therefore be running out of ram."
* BTW, I really don't like the sound of "executing in RAM". It doesn't
execute *in* RAM, it executes in the CPU/ALU or whatever. "From RAM"
would be clear and unambiguous.

Alternatively:
You have not designed in enough memory of one kind or the other to
encompass the program you are trying to put into it. Don't tell the boss
until you have a solution or can blame it on someone else.
