Powering a micro from a single AAA

My MP3 player runs on a single AAA. Do you think the voltage is being stepped up with a switcher or are there low voltage micro controllers that will run from 1 - 1.2V?

Stepped up with a switcher, probably as part of an ASIC.

It probably uses on of these (or one of dozens like it from Maxim, TI, National, etc.):
