Of course there's a limit. You just aren't likely to hit it with the

http://www.squid-cache.org/Doc/config/cache_replacement_policy/ and
http://www.squid-cache.org/Doc/config/memory_replacement_policy/ (The
second link references the first, but would be the more relevant
directive if you are going to be using a memory-only Squid).
