    This information is in the Stratix family data handbook (www.altera.com --> devices --> statix --> literature web page). In the architecture or memory chapter there are tables that describe how many M-RAMs, M4K, etc. are in each Stratix device type. 1 M-RAM = 64 Kbytes, 1 M4K = 512 bytes. Additionally I believe the Quartus compilation report resource summary will tell you how many memory blocks are available, as well as how many are used in your current design.
