pdfTeX in DVI mode:

Here is how much of TeX's memory you used:
 360 strings out of 493849
 5894 string characters out of 3149147
 51381 words of memory out of 3000000
 3713 multiletter control sequences out of 15000+200000
 3938 words of font info for 15 fonts, out of 3000000 for 9000
 714 hyphenation exceptions out of 8191
 23i,5n,31p,220b,107s stack positions out of
5000i,500n,10000p,200000b,50000s

and similar pdfTeX in PDF mode:
