Excerpt from
http://www.imagecraft.com/devtools_CPU12.html :

"STANDARD: ... Support for up to 64K byte of unpaged memory and 64K of 
expanded program memory. ...
ADVANCED: Standard + allows access to unlimited amount of expanded program 
memory. "

RAM is also unpaged memory. And in total, using STD, you have unlimited 
nonpaged memory plus 64k of paged memory. I'm saying unlimited nonpaged 
memory because even if you had PRO or ADV -  you couldn't use more than 2^16 
of nonpaged memory :-)

Edward
