   TCP_HIT happens when squid took the requested information from the 
cache directories, ie, from the disk.

   TCP_MEM_HIT happens when squid took the requested information from 
memory, ie, RAM memory.

   Of course you'll see less TCP_MEM_HIT than TCP_HIT because the 
amount of memory and disk are VERY big. I dont know your situation, but 
usually we have several GBs of cache in disk and only some few hundreds 
of RAM memory allocated to squid. That's because you'll almost always 
see a LOT of TCP_HIT and only some few TCP_MEM_HIT.
