If you have a Cisco login, you can use the 2600/3600/3700 Memory calculator tool to know the memory requirements based on the modules and IOS version.

It is not just a matter of the IOS Version. You also need to know the feature set. Within an IOS version the standard ip only requires the least memory and enterprise+ can require 2 to 4 times as much. The feature set is generally identified by one or two characters in the image name. The js in this image are the feature set.
IOS (tm) 3600 Software (C3660-JS-M), Version 12.2(3), RELEASE SOFTWARE (fc1)
