Going through the [list of economies that currently use the dollar](http://en.wikipedia.org/wiki/Dollar#Economies_that_use_a_dollar), it looks like no modern economies that use the dollar use any subdivision besides cents. In [Hong Kong](http://en.wikipedia.org/wiki/Hong_Kong_dollar), the 1/100 subdivision is still called a cent, but it's no longer in circulation. In [Taiwan](http://en.wikipedia.org/wiki/New_Taiwan_Dollar), cents aren't used in coin form (only in financial markets). In countries like [Malaysia], the word *sen* is used, but it's a translation of the word *cent* (even though the word for the actual currency, *ringgit*, isn't a translation of the word "dollar"). 

On a historical note, however, the [Spanish Dollar](http://en.wikipedia.org/wiki/Spanish_dollar) was subdivided into 8 *reales* in order to match the German thaler (the word that forms the basis for the English word "dollar"). It's not a current example, but it's interesting nevertheless.
